Series R52

Torque Sensor For Tool Calibration

Calibrate torque tools with this torque measurement sensor, or use it as a component of a torque testing system. Tapped holes on every surface allow for easy mounting to a work bench, or fixture within a testing system. Capacities available from 10 ozFin to 100 lbFin (7 to 1,150 Ncm).

Requires a Mark-10 indicator, available separately.

  • Rugged aluminum housing
  • Universal mounting
  • May be used for torque tool calibration or as a component of a torque testing system
  • NIST-traceable certificate of calibration with data is included. If the sensor is ordered with an indicator, a certificate for the set (indicator + sensor) can be supplied upon request, at no additional charge.
  • Warranty: 3 years
  • Accuracy:  ± 0.35% of full scale + indicator
