Rotary Torque Sensor – Non-Contact w/ Integrated Encoder
Release Date: 12/14/2006

Unlike reaction torque sensors, rotary torque sensors can rotate inline with your part or rotating drive shaft and you don’t have to worry about the cable getting tangled. One of the popular FUTEK rotary torque sensors is Model TRS605. A key feature of this stable strain gage based sensor is the non-contact signal transfer which eliminates conventional slip rings that could cause friction and eventually wear down the brushes and rings. This feature also allows for higher RPM speeds and lower capacity ranges. The unit provides ± 5 VDC amplified output in CW & CCW. This makes the unit easier to integrate with PLC’s and DAQ systems. In addition to the benefits mentioned, this model also comes with an integrated encoder. This feature gives angle/position or RPM feedback with TTL output which the user can utilize to calculate power.

The TRS605 rotary torque sensor can be used for a variety of applications. It can be used in dynameters to determine hose power and torque of a motor / engine. It can also be used with generators to determine efficiency or with a power tool to monitor running or peak & breakaway torque. In the automation industry, it could be used to give torque feedback during production.
