Dynamometer Equipment

A device for measuring mechanical power, as a balance especially measures the output or driving torque of a rotating machine. A dynamometer can be also used to determine the torque and power required to operate a driven machine such as a pump. For that purpose, a motoring or driving dynamometer is used. In a number of roles dynamometer are utilized in addition to being used to determine the torque or power characteristics of a machine.
Uses of dynamometers:
Dynamometer Equipment
  • Restorative road loading of either the engine dynamometer or using a chassis dynamometer a full powertrain dynamometers are used.
  • With a simple power and torque measurements, dynamometers can be used as a part of testbed for a variety of engine development activities.
  • Calibration of engine management controllers, detailed investigations into combustion behavior and tribology dynamometers are used.
  • A high performance pressure transducer is required for its ability to measure accurately in rugged conditions.
  • Another advantage of transducer is its flexibility and it can withstand mechanical shock, corrosion, and other extremes found in harsh testing environments of dynamometers.
  • An essential component of a dynamometer equipment is its data acquisition system. The system is typically comprised of two units, a commander and workstation.
  • In the dynamometer tests the workstations comfort and data acquisition systems accuracy, depends on its ability to measure data correctly.
  • In a dynamometer the commander, a desktop computer operated by windows based software that issues commands to the workstations.
Some of dynamometers types and used for such as – 
  • Engine dynamometers – it is used to test engines removed from the vehicle and power test brake engine dynamometers excel at testing wide range of power input with one dynamometer.
  • Chassis dynamometers – it is used for complete power train diagnostics, transmission, drive train, retarder and brake testing, as well as alignment certification can be performed.
  • Electric motor dynamometers – it is specialized type of adjustable speed drives and when equipped with appropriate control units, electric motor dynamometers can be configured as universal dynamometers.
  • Hysteresis dynamometers – it is use as a steel rotor that is moved through flux lines generated between magnetic pole pieces and the benefit of hysteresis is an Eddy absorbers.
