Products/Services for Optical Rotary Torque Transducers

  • Force and Torque Instruments-Image
    Force and Torque Instruments - (307 companies)
    Force and torque instruments are used to measure force, weight or torque. Some can measure force and torque by changing the sensor / transducer. Force or weight measurements include tension or compression loading, units are lbs., Newtons... Search by Specification | Learn More
  • Torque Sensors-Image
    Torque Sensors - (185 companies)
    ...are categorized into two main types, reaction and rotary. Reaction torque sensors measure static and dynamic torque with a stationary or non-rotating transducer. Rotary torque sensors use rotary transducers to measure torque. Specifications. Important... Search by Specification | Learn More

    Rotary Solenoids - (73 companies)
    Rotary solenoids are electromechanical devices that convert axial motion into rotary strokes. These transducers have a higher starting force (torque) than linear solenoids, and are more resistant to shock. How to Select Rotary Solenoids. Rotary... Search by Specification | Learn More
  • Rotary Position Sensors-Image
    Rotary Position Sensors - (214 companies)
    Rotary position sensors include potentiometers, resolvers and a variety of magnetic and capacitive technologies. Sensors are designed for angular displacement less than one turn or for multiturn displacement. How to Select Rotary Position Sensors... Search by Specification | Learn More

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....
