Rotating torque meter – Serie CR1

APPLICATIONS

  • Control of process with torque regulation in order to optimise the stress under which the machine is to be operated.
  • Measurement of ‘on-line’ torque on a transmission shaft, a driving shaft
  • Tightening tools
  • Control and calibration of electric and hydraulic screwing machines and torque wrenches

DESCRIPTION

CR1 torque sensors operate on the strain gauge principle and supply an analog output signal of ±0
... 5 V, which is contactless transferred. Also available with integrated rotational angle/speed
measurement.
  • Smart (integral measuring electronics)
  • Interference resistance due to active torque output (±5 VDC), electrically isolated from supply and measuring signal
  • Non-contact signal transfer
  • Unipolar supply
  • Highly responsive to dynamic peaks
  • Maintenance-free
  • Standardized mechanical connections
  • 1/4" hex socket DIN3126
  • Square socket (size depending on measuring range)
  • Cylindrical shaft ends
  • Extremely compact
  • Suitable for pulse tool operation
  • Optional rotational angle measurement
