Product outline Both (C) and (RC)

New installation option of UTMⅢ!
New type for firm usage & fix torque meter!

●Wants center point of axis as reference for installation
●Wants to stop vibration & fix main unit
●Other reasons that require to fix main unit

Installation example


Rotary encoder (RC)

3600 pulses in 1 rotation. (0.1 degree per pulse)
●Measurement range: 0.05 to 500 Nm
●Optical encoder 3600 C/T
Ideal for detecting torque versus angle
*Maximum rotation speed is 5000 Frpm.
