Rotating torque meter – Serie CR7

APPLICATIONS

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

DESCRIPTION

Type 4503A... torque sensors with built-in speed sensor operate on the strain gauge principle. An integral, digital measurement conditioning system produces analog or digital output signals.
  • Rated torque: 0.2 ... 5,000 Nm
  • Ratio for second range: 1:10 or 1:5 of rated torque
  • Speed ranges up to 50,000 1/min
  • Accuracy class in standard measuring range: 0.1
  • In the extended measuring range: 0.2

- Integral speed sensor - Serial data output RS-232C for torque signals
Additional advantages of second range
- Natural overload protection of smaller range because of special design - One sensor for two separately calibrated measuring ranges.
