Rotary torque transducer FYE is a slip-ring type torque measuring unit intended for rotating torque measurement.Both mV/V signal and amplified 0-5V/0-10V/4-20mA output is available for model FYE.The inner keyed shaft end normally connects with servo motor shaft and works as input end,the outer keyed shaft end has the same specifications as motor shaft and works as output end,dimensions of both sides can be customized to meet the mounting requirements, which makes torque sensor FYE extremely suitable for torque measurement of servo motors with different specifications.
