Rotary transformer method torque transducer TMNR-ME series
Appearance
・ TMNR-*ME type Torque meter can measure the torque from the geostationary axis to the high-speed spindle by the double bearing adoption. As the strength is higher than the standard model (TMNR type) both for radial and thrust, and a direct coupling with a propeller shaft etc. are more possible by making the bearing double. Because the dropping lubricant method is assumed to be a standard, the torque measurement to which a heavy load hangs is possible. (Please inquire for a grease lubrication method.)
・ It is possible to use it for the test stand for not only the torque measurement but also the instrumentation control field , for instance, the car etc. because of the efficient rotary transformer adoption.
・ Because the rotational speed can be measured by installing the rotation detector(option), the horsepower of the motor output etc. can be measured.
