Strain gauge based torque transducers are suitable for use in a wide range of industries. Due to their extraordinary variety and flexibility of design, they can handle the most diverse and challenging applications. They are
very often the most cost-effective
and efficient solutions to challenges requiring durable, dependable, and precise torque measurement devices.

Strain gauge based torque transducers convert a torque into a measurable electrical signal. Their function is based on the piezoresistive effect: the ability of the strain gauges to change their resistance value in response to the physical deformation of a material caused by torque. By wiring the strain gauges in a Wheatstone bridge arrangement, these small changes in resistance can be exploited to give rise to a precise electrical signal proportional to the applied torque. When the Wheatstone bridge is coupled with a specially engineered metal element body, a torque transducer is born. And following careful compensation for temperature changes and precise testing, it is ready for success in the field.

Reaction torque transducers are designed to measure non-rotating twisting loads. Often used to monitor bolt tightening, container sealing, and engine start-up, these transducers are found in almost as much variety and frequency as their load cell cousins. Available with different combinations of shaft, flange, bolt, and socket mounting options, they can measure torques as small as a few inch-ounces or as large as several thousand foot-pounds.
