BLRTSX-R/RA Brushless Rotary Torque & Angle Shaft Sensor


+ Enlarge Picture

  

The Mountz brushless rotary torque and angle shaft sensors are design for precision torque testing. Used in-line with rotating shafts or nutrunners for feed back control. Ideal for motor testings, high RPM Tools or rotational measurement applications.
  • Non-contact signal transfer and maintenance free.
  • The brushless rotary torque & angle sensor is a compact design & bi-directional.
  • Used in-line with rotating shafts or nutrunners for feed back control. Motor testings, high RPM Tools or rotational measurement applications.
  • RA Models:
    - Angle output 2-channel quadrature
    - 360 pulses per rotation
    - Ability to measure the rotation angle of a fastener
    - Joint rate & breakaway torque can be measured too
  • Features ARCII technology, an instant auto-recognition system of the BLRTSX connected to the PTT or LTT.
  • Accuracy ± .2% of full scale*.

Note: * This is the “stand alone” accuracy for the torque sensor.
When the torque sensor is coupled with a Mountz torque tester, the system accuracy is:
Accuracy ± 0.5% of reading from 20% to 100%
Accuracy ± 1% of reading from 10% to 20%.
