Conduct Research

The subject of torque measurement has previously been addressed extensively. Most of the. existing transducers either rely on low voltage analogue systems (e.g. conventional resistive. strain gauge) or complicated mechanical assemblies by physically assessing displacement, i.e. optical systems...

A controller then uses a translation table in memory to relate the code read from the transducer into system position. Absolute encoders are available in both rotary and linear optical types. Tachometers are probably the most widely used velocity transducer....
