To ensure the precision of the drive power or the efficiency
which are essential to meet the strict environmental regulations in the marine engine industry, besides the measurement of high torque, the calibration and traceability
of this physical quantity are increasingly coming into focus. Basically, the techniques used in torque calibration are subdivided in lever-arm/mass system and reference transducer.
Lever-arm/mass systems: A precisely defined torque is generated when the weight force of calibrated masses acts on the test specimen by means of a lever arm of known length .
- The second technique in torque calibration is using a force reference transducer with a lever arm .
- The third principle is a torque reference transducer which provides the reference value. Systems with torque reference transducers can use any mechanism to generate the torque which is then measured with the torque reference transducer .
