Rotary Transformer - Non Contact - Unamplified

Honeywell offers a line of non-contact rotary transformer shaft and flange mount torque sensors ideal for test installations running long-term durability testing. The non-contact nature of the signal transfer virtually eliminates the need for maintenance. High overload protection with high signal output helps prevent potential damage to the sensor. Carrier frequency excitation provides increased signal/noise immunity. The rotating transformers differ from conventional transformers only in that either the primary or secondary winding is rotating. One transformer is used to transmit the AC excitation voltage to the strain gage bridge, and a second transformer to transfer the signal output to the non-rotating part of the transducer. Thus, two transformers replace four slip rings and no direct contact is required between the rotating and stationary elements of the transducer.
