A line of enhanced accuracy rotary transformer torque sensors often ideal for test installations running long-term durability testing. 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. Extended speed range allows shaft rotation up to 27000 RPM. Capacity range from 100 in-lb to 100000 in-lb for shaft mounting configurations.
