This article takes an in-depth look at dynamometers.
You will learn more about topics such as:
A dynamometer is an instrument designed to measure force, tension, weight, or pulling forces. It gauges torque, force, velocity, and power essential for operating a motor by evaluating torque and rotational speed concurrently.
Although traditionally used for measuring engine torque, the scope of dynamometers has broadened to encompass the measurement of weight and tension. These devices are critical for monitoring tension levels in telephone wires, suspension bridges, elevator cords, and ski lifts.
When used as tension measuring tools, dynamometers are vital for ensuring the safe application of lifting rigs, cranes, and cables by accurately tracking loads and preventing overloads. Available in a range of designs to suit diverse applications, they are often preferred to crane scales due to their ease of setup and mobility.
For a dynamometer to maintain its precision and accuracy, regular calibration is crucial. Therefore, dynamometers come with a variety of calibration techniques and are built to withstand the variety of environments they encounter. This robust construction makes them indispensable for analyzing both pull and push forces.
Within a dynamometer, exerting force on a flexible metal ring results in its deflection, enabling the measurement of the applied force. This measurement is essential in the auto industry for determining horsepower, power absorption, and rotational speed. Additionally, in construction, dynamometers are used to monitor and evaluate the tension and pull forces on structural elements to ensure strength and load-carrying capacity.
A significant advantage of dynamometers is their adaptability across numerous applications. Whether measuring torque or pull forces, dynamometers stand out for their high accuracy and dependability.
To understand how a dynamometer works, imagine a spring mounted in two parts: one end anchored to a base and the other end connected to the force being measured. As the force stretches the spring, a reading appears on a scale. This fundamental principle is at the core of how mechanical dynamometers operate, akin to a spring balance. The most common measurement units are Newtons (N), pounds-force (lbf), and kilograms-force (kgf), enabling versatile use for diverse industrial and laboratory testing applications.
While this simple model can provide basic force readings, it lacks the capacity and precision required to measure the horsepower and torque produced by a high-performance engine—such as a 250 hp or more automotive engine. For these demanding tasks, a more advanced type—often referred to as an engine dynamometer or chassis dynamometer—features a robust design capable of handling greater power output, rotational speed, and dynamic load variations. These advanced dynamometers are engineered to ensure safety, durability, and accuracy in high-power, real-world testing environments.
A large dynamometer functions as a variable load—sometimes known as a load bank—connected to the output shaft of an engine or electric motor. As the motor or engine operates, the dynamometer absorbs and measures the generated power, providing key performance data such as torque, brake horsepower (BHP), power curves, and rotational speed (RPM). This absorbed energy is typically dissipated through electromagnetic, hydraulic, or eddy current resistance methods to safely manage substantial heat and kinetic energy produced during testing.
In today's technology-driven world, modern dynamometer systems feature advanced data acquisition and analysis capabilities controlled by specialized computer software. These dynamometer control systems not only automate testing sequences but also provide precise, real-time monitoring for engineers and technicians. The majority of industrial and automotive testing labs use sophisticated Windows-based software packages, which allow for configurable data logging, visualization, and comprehensive reporting. Some legacy DOS-based software solutions remain in use for specific industrial applications.
The software provides readings and diagnostics that can include:

Engine and chassis dynamometers are also essential tools in vehicle testing, racing applications, automotive diagnostics, and industrial quality assurance programs. They play a key role in evaluating aftermarket modifications, conducting endurance tests, and validating manufacturer warranty claims. Investing in high-precision dynamometer testing services ensures accurate, reliable output, helping businesses meet industry standards and end-user expectations.
When used as a force gauge, a dynamometer measures both tensile (pull) and compressive (push) forces across a wide range of engineering disciplines. There are two main types of dynamometer force gauges: digital and mechanical. A digital dynamometer is equipped with a load cell sensor that converts applied force into highly accurate electrical signals, which are displayed on an LCD screen for precise measurement. In contrast, a mechanical dynamometer often uses a strain gauge that deforms under load, translating physical movement into readable values, sometimes through analog dials, and in other cases with electrical output.
Dynamometer force gauges offer measurements in industry-standard units, including Newtons (N), pounds-force (lbf), kilograms-force (kgf), and, for specialized applications, Pascals (Pa) for pressure assessment. These highly accurate and reliable devices are capable of measuring a vast range of forces—from delicate biomedical testing loads to extremely large loads in industrial crane and hoist safety testing, construction, and aerospace environments.
Beyond standard material testing and quality assurance, engineers and safety professionals use dynamometer force gauges for calibration, proof loading, overload detection, and certification of lifting equipment. Their robust construction, high-resolution sensors, and built-in data logging ensure compliance with ISO, ASTM, and OSHA standards. By choosing the appropriate dynamometer for your application—digital or mechanical, portable or bench-mounted—you can achieve superior accuracy, repeatability, and traceability in your force measurement process.
During the engineering design process, selecting the correct engine or electric motor size to operate a machine or industrial system is crucial for performance, efficiency, and safety. To achieve this, professionals rely on driving dynamometers.

Measurements often center around the length-tension relationship of specific muscle groups, comparing maximum voluntary contraction to optimal muscle length. Accurate, repeatable data enables clinicians to diagnose neuromuscular conditions and customize strength training protocols.
A grip strength or hand dynamometer offers reliable, standardized measurement of hand and finger muscle strength for occupational therapy, ergonomics studies, sports training, and clinical diagnosis. Hand strength assessment is crucial for identifying carpal tunnel syndrome, nerve and tendon injuries, arthritis, and neuromuscular disorders—supporting diagnosis, monitoring rehabilitation outcomes, and determining treatment effectiveness. Regular hand strength measurement is also important in workplace health and safety programs, research studies, and pre-employment screenings.
Speedometer dynamometers—also known as eddy current dynamometers—use principles of electromagnetism to provide accurate vehicle speed measurement. By exploiting the interaction between a rotating metal disc, cables connected to the wheels, and magnetic fields, they deliver both analog and digital speed outputs. These precision instruments are used for calibrating speedometers, verifying vehicle instrumentation, and diagnosing drivetrain issues. Speedometer dynamometers are found in auto repair shops, calibration labs, and R&D centers dedicated to automotive safety and regulatory compliance.
A towing dynamometer is an advanced testing trailer used to simulate variable loads and road conditions for vehicles during performance assessment. Equipped with an eddy current absorber and integrated axle system, towing dynamometers can apply precise resistive forces to the test vehicle, measuring power output, tractive effort, driveline efficiency, and fuel economy. Load cells provide highly accurate force measurements, making towing dynamometers indispensable for heavy-duty trucks, commercial vehicles, off-road equipment, and compliance-driven field testing. These tests facilitate vehicle optimization and help manufacturers comply with regulatory requirements and safety standards.

Dynamometers come in various types designed to attach to machines and apply braking forces to measure rotations per minute (RPM). The primary categories are absorption (or passive) dynamometers and universal dynamometers. Absorption types are used for driving tests, while universal types serve both absorption and driving purposes.
While these broad categories cover many dynamometer types, each includes specialized models tailored for specific testing needs. The extensive range of devices within these categories provides detailed information and data for various applications.
Among the specialized tests, the static tension test is notable. This test evaluates a material's breaking point and elongation under constant force or load, applied while the material remains stationary. Static tension measurements are crucial in rigging and lifting operations, and can be conducted either vertically or horizontally using devices such as clamp-on tension meters for horizontal measurements and clip-on dynamometers for vertical measurements.
The Prony brake dynamometer, conceived by Gaspard de Prony during the early days of the industrial revolution, is one of the most basic types of dynamometers. It consists of brake pads that apply pressure to a spinning wheel connected to a motor. This friction between the pads and the wheel helps reduce its speed. The main function of the Prony brake dynamometer is to gauge the braking power.
Tension dynamometers are commonly used instruments for measuring the tension in cables on suspension bridges and for adjusting the tension in electrical and telephone lines. They are crucial for determining how much tension a cable can handle before it breaks, providing precise measurements of its strength.
These dynamometers typically feature shackles, hooks, and pins to connect them to scales and cables. They operate similarly to strain gauges by using a load cell to assess force, load, and tension. Unlike tension meters that measure the tensile force in wires, tension dynamometers show the force exerted between two shackles aligned along the same axis. Various load cells and measuring devices are incorporated into these instruments.
Available in compact and portable designs, tension dynamometers are noted for their high accuracy and ease of use. They are commonly found in diverse settings, such as construction sites, foundries, oil rigs, and anywhere heavy lifting equipment is used. These devices help ensure that lifting machinery operates within safe tension limits and prevents overloading or excessive strain on cables and guy wires.
Wire tension meters, also referred to as wire rope tension meters or yarn tension meters, are specialized types of tension dynamometers featuring a load cell and wire tensioner for monitoring tension. These versatile devices can be adapted to various wire qualities and manufacturing processes. By maintaining consistent tension, they ensure high-quality coil windings and efficient processes while minimizing the risk of wire failure or breakage.
Wire tension dynamometers come in two main types: static and dynamic. Static models provide fixed tension measurements, while dynamic models offer readings during active operations. These tools are well-suited for varying conditions and wire types, ensuring precise and consistent coil windings.
Dillon AP dynamometers are designed to measure tension, traction, and weight on cables used for bridges and adjusting guy wires, ropes, and wires. They are favored for their accuracy, with a tolerance of +/-0.5% of full scale. The capacity ranges from 500 lbs. to 100,000 lbs. (200 kg to 50,000 kg) and are available with 5 in (125 mm) or 10 in (250 mm) dials, which denote different models.
At the heart of the Dillon AP dynamometer is a steel flexing beam encased in an aluminum housing, with a dial protected and cushioned by a rubber gasket. There are three versions of Dillon dynamometers: AP, EDjunior, and EDXtreme, with the AP model being the most versatile and widely used.
Assembling a Dillon AP dynamometer is quick, requiring only AA batteries for power. Developed by W. C. Dillon, these mechanical dynamometers are specifically designed to measure tension in telephone wires. The unit is positioned on a line, with the dial zeroed before applying force, and the gauge movement provides a precise and accurate reading.
A tensiometer measures soil moisture by assessing the negative pressure, or tension, which reflects how much effort plant roots must exert to extract water from the soil. This tension indicates the force required by plants to pull water through soil pores. Larger pores allow for easier water extraction and require less force, while smaller pores necessitate greater force, increasing the tension as the soil dries.
As the soil loses moisture, plants need to exert more force to extract water, resulting in higher tension values and indicating water stress. Tensiometers feature a porous ceramic tube filled with water, which interacts with the soil. When the soil dries out, water moves from the tube to the soil pores, creating a vacuum within the tensiometer. This vacuum is measured by a gauge, which provides readings in kilopascals or centibars.
The tensiometer's measurement process remains unaffected by variations in soil texture, temperature, or salinity. While tensiometers are effective in signaling when irrigation is needed, they do not measure the exact quantity of water required. For optimal accuracy, tensiometers should be installed in multiple locations within a field, chosen according to the irrigation methods and system types used.
An eddy current dynamometer measures the torque and power of the prime mover, which is a motor or engine. The rotor turns by the force of the prime mover shaft, and voltage is applied to the stator housing. Magnetic flux is generated, which is cut off by the rotor. An eddy current that is opposite to the change in the magnetic flux is generated in the rotor.
The rotor aims to manage and decrease rotational speed, while the prime mover keeps the speed consistent through its torque. An eddy current dynamometer measures this torque. Eddy current dynamometers are utilized in various applications, such as turbines and mining or drilling machinery.
A hydraulic dynamometer has semicircular vanes placed in a rotor and stator. Water flows in a toroidal vortex around the vanes and creates a torque reaction in the dynamometer casing that is resisted by the dynamometer and measured by a load cell. The construction of a hydraulic dynamometer is similar to a fluid flywheel that measures the frictional force between impeller vanes and a moving fluid.
Absorption dynamometers generate torque by applying constraints to a rotating shaft via mechanical, fluid friction, or electromagnetic methods. These torque-inducing elements are set up in pairs to prevent the impact of transverse loads. Known for their precision, absorption dynamometers are ideal for applications requiring continuous load transmission.
Absorption dynamometers are designed to measure and absorb power. Various types, including eddy current, hydraulic, and Prony dynamometers, utilize power absorption principles for their measurements.
A driving dynamometer assesses the requirements for a motor needed to operate an engine or electric motor. It consists of a motor equipped with measurement meters and monitors connected to the device under test. The data from these instruments provide insights into the power, force, and speed being utilized.
An AC dynamometer applies power to an engine and absorbs power, such as braking force, from the driveshaft. This permits the dynamometer to simulate the external forces on the engine. AC dynamometers can use direct current (DC) as well as AC and can be a load or prime mover to measure rotational power and torque. The prime mover can be an electric motor, or a turbine driven by wind, water, or steam. It is a simple testing device that can provide a range of torque values.
AC dynamometers offer an efficient way to compare actual performance against design specifications. They play a crucial role in advancing product development by improving marketable products and extending their lifespan and performance.
Water brake dynamometers are suited for high torque, low-speed diesel engines used in mining, marine, and naval contexts. They can accommodate engines with both clockwise and counterclockwise rotations. These dynamometers, a type of hydraulic absorption device, connect to the engine’s crankshaft and use water to create braking force.
Inside the dynamometer, a rotating blade directs the water to generate braking force against the crankshaft. The engine's power is determined by the amount of heat produced, which correlates with the volume of water used—the greater the water flow, the higher the braking force required.
Fluid dynamometers operate similarly to water brake dynamometers but utilize either water or oil to drive the crankshaft. Like water brake dynamometers, the turning of the impellers generates heat, which is measured by the dynamometer. Gears connected to the dynamometer's shaft transmit the recorded data to a device that gauges the force.
A universal dynamometer differs from an absorption dynamometer in that it can measure both absorption and driving characteristics of the device under test. While it absorbs force and power, it also drives the engine to assess factors such as friction and pump losses, among others.
Chassis dynamometers are torque measuring devices that measure what is produced by the movement of a vehicle's wheels. They are available in fixed configurations or portable units. The purpose of chassis dynamometers is to simulate road conditions, including all the forces that attack a vehicle during operation.
The test involves accelerating, braking, and decelerating the vehicle to gather the required data. Various chassis dynamometer designs are available to evaluate different driving conditions and challenges.
The primary types of chassis dynamometers are:
The process of using an engine dynamometer is slightly more complicated than the use of other dynamometers. The size, weight, and performance of the engine are the determining factors related to selecting a proper dynamometer. Unlike chassis dynamometers, engine dynamometers test and tune engines.
Engine dynamometers generate extensive data and require a computer interface for recording and displaying the results. The key distinction between different types of engine dynamometers lies in their application: street engines versus heavy-duty engines, like race cars or trucks, due to significant differences in torque. These dynamometers are utilized to measure dynamic force and torque.
A rope brake dynamometer measures engine power using a rope wound around a drum connected to the output shaft. One end of the rope is linked to a spring balance, while the other end is attached to a loading device.
In this dynamometer, power is absorbed through the friction between the rope and the drum. To manage the heat generated by this friction, a cooling mechanism is required. Although rope brake dynamometers are relatively simple to construct, they often provide less accurate data due to variations in the friction coefficient.
A crane hook dynamometer is a type of tension load cell dynamometer used for under-hook crane weighing, proof load testing, and crane calibrations. They come in various forms and sizes, including models capable of measuring forces exerted by large ship-loading cranes and spanning several feet.
Crane hook dynamometers are available in both wired and wireless versions, with some featuring a handheld device for digital readings. Connected to the crane’s hook, these dynamometers use a microprocessor to ensure high precision. The handheld wireless indicator simplifies and enhances the convenience of calibrating the device.
These tension dynamometers convert force readings into electronic signals, aiding in preventing overloads, monitoring rig tension, and evaluating loads.
A dynamometer's fundamental functions are to measure torque, force, and power. These tasks are carried out through specific procedures: step test, sweep test, and transient test. Each procedure is chosen based on the type of data required.
A dynamometer is equipped with a data acquisition system comprising a commander and a workstation. Like other modern testing equipment, it connects to a computer that sends commands to the workstation. After the commands are executed, the workstation operates the dynamometer and collects the programmed data, which is then sent back to the command computer.
Step tests are conducted by brake dynamometers where an engine runs at a constant RPM for a set duration. Data is collected at each RPM level before increasing to the next. This method benefits from minimal acceleration effects, reducing the influence of inertia and the dynamometer on torque measurements.
The sweep test involves accelerating the engine at a steady rate, such as 100 RPM per second, to closely replicate real driving conditions. Success in this test depends on maintaining a constant and precise acceleration rate, which is managed by the dynamometer’s control system.
The inertia sweep test aims to closely simulate actual driving conditions. Although it may not provide identical data to on-road driving, it effectively measures the engine's inertial resistance.
The loaded sweep test has two versions, which are simply fixed and controlled. With the simple fixed test, the engine accelerates at its own rate. Power is determined by the power required to accelerate the dyno. As the name indicates, the controlled version of a sweep load test controls the acceleration rate.
The transient test is designed to assess various driving patterns a vehicle may encounter, including throttle changes and speed fluctuations.
Variations of the transient test include cold starts followed by hot starts. Its primary goal is to measure emissions in accordance with Federal Test Procedure (FTP) standards. During FTP testing, the load factor should be maintained between 20% and 25% of the engine's maximum power.
Typically, the first data point analyzed from a dynamometer is the peak power. While this figure is crucial, it is more significant to evaluate the average power across a useful RPM range. This useful range is defined by the minimum RPM of the engine at full throttle.
Managers and supervisors in industry are focused on ensuring optimal performance from their equipment. Regular inspection, assessment, examination, and testing of machines and engines are essential. A dynamometer is an excellent tool for evaluating the power and capabilities of critical equipment, ensuring that processes run smoothly and efficiently.
A dynamometer scientifically measures the speed, torque, and power of engines, machines, and powered tools. Its applications span various industries, including the collection of data on motors, engines, pumps, and generators.
A key function of a dynamometer is delivering precise and accurate data. It is particularly useful for optimizing fuel use and identifying fuel waste. The data obtained helps in fine-tuning and adjusting machinery and motors cost-effectively.
While testing devices are invaluable, their effectiveness depends on the quality of data they provide. Dynamometers offer high-quality, precise, and accurate data, clearly and concisely. They can assess both large and small equipment and are available in portable models.
Dynamometer manufacturers offer a broad range of sizes to suit various applications. Water brakes are suited for large engines, whereas eddy current brakes can measure engines up to 250 hp. The diverse options ensure that you can find a dynamometer tailored to your specific needs.
The key attribute for any industrial instrument is the ability to withstand and endure the conditions where they are used. Dynamometers are solidly built from metal alloys. Producers are well aware of the conditions where their devices will be used and plan them to be durable and strong.
Testing engines involves general parameters for adjustments and maintenance. Lifting and rigging operations have distinct requirements compared to engines and motors. Specialized dynamometers provide data essential for making lifting and rigging operations efficient and safe.
