Torque Transducer Shaft type transformer method torque transducer

Rotary transformer method torque transducer TMNR series


・ TMNR type Torque meter is a highly effective rotary transformer to transmit the electric signal that the sensing point of torque detected.
Therefore, the steady performance is gotten as for the measurement for a long time, because driving side and the measurement side are noncontact.
It is used for the instrumentation control only for the measurement.
It is possible to use it for not only the torque measurement but also the instrumentation control field, For instance, control of stir power and kneading power in food chemical industry etc., because of the efficient rotary transformer adoption.
・ The horsepower measurement on motors can be done, because the rotational speed can be measured by installing rotation detector (Options).
