About the 01325-square Rotating Torque Sensor

An angle encoder and round or square housings are available with this model. Square housings have optional foot mounts. These strain gage based sensors are designed to measure torque in low capacity applications such as checking calibration in mechanical torque wrenches and air powered nut runners. The design incorporates a coin silver slip ring assembly that transmits excitation voltage to, and output signals from, the rotating drive sensor. These sensors can be supplied with Auto-ID, which eliminates scaling when used with the PMAC 3000 instrument.

Available options for 01325-square:

  • 4 pin Bendix connector (non-Auto-ID)
  • 10 pin Bendix connector (Auto-ID)
  • Square or Hex drive
  • Integral angle encoder – 1024 ppr or 60 tooth mag pick-up (requires 10 pin connector)
  • Integrated amplifier; +/-5V, +/-10V or 4-20mA
  • Foot mount
