About Our Torque Transducers

Vibrac's patented optical torque transducer technology provides a unique method for precise and accurate torque measurement. The durability and reliability of Vibrac's torque sensors has been demonstrated by the more than 20 years of industrial application in both laboratory and production environments.

The transducers use encoder-type discs to shutter light proportionally to the angular displacement of a torsion bar. This light is then converted by high output photocells into a current that is likewise proportional to the torque.

This methodology provides for the manufacture of both dynamic and static non-contacting transducers with relatively low inertia for any given torque range. The high output current of these optical transducers results in a noise free signal in an electrically noisy environment. Vibrac® provides Torque Transducers for both static and dynamic applications, which cover the range from 0.05 oz-in to 400 in-lbs.

  • No Slip Rings

  • No Brushes

  • Long Trouble-Free Service

  • 100% Overload Capability

Vibrac® also offers a full line of data display instrumentation for controlling and processing the output of the transducers.

All transducers used in conjunction with any of Vibrac's instrument packages are calibrated for zero and span with a single adjustment.

Please note: All transducers require Vibrac signal conditioning instrument or card.
