Rotating Contactless Dual Range Torque Transducers and Sensors offer the advantage of two calibrated operating ranges in one sensor that save the hassle and cost of applications where high accuracy test and measurements across a wide range are required. Dual range torque sensors with DIN standards accuracy class of 0.1 have a range of 0.5 N m up to 20000 N m enabling range switching and high peak-to average ratio torque measurement. In particular, if the peak torque is unknown, dual range torquemeter can reduce the risk of damage from unexpected torque spikes. Dual Range Torque transducers are primarily used in automotive and process engineering, aeronautic industry and electric motor manufacturing, that find applications in research and development laboratories, production and quality assurance fields.

transformer coupling to transmit power to the rotating sensor. An external instrument provides an AC excitation voltage to the strain gauge bridge via the excitation transformer. The sensors strain gauge bridge then drives a second rotary transformer coil in order to get the torque signal off the rotating sensor. Specialized signal conditioning is required.
transformer coupling to transmit power to the rotating sensor. The difference is the rotary transformer coupling is used to power a circuit on the rotating sensor. Then the circuit provides excitation voltage to the sensor’s strain gauge bridge, and output digital signals. The digital output signal is transmitted via infrared light, to stationary receiver diodes, where another circuit checks the digital signal for errors and converts it back to an analogue voltage.
Since the sensor’s output signal is digital, it is much less vulnerable to noise from such sources as electric motors and magnetic fields. Unlike the rotary transformer system, an infrared transducer can be configured without bearings as a true maintenance free, non-contact, no drag sensor.
A speed-/angle- sensor integrated in the torque dynamometer is available for many rotating toque cells.
