Description

Torque sensor with quick-change chuck DRFSk

Features

  • No service needed because of contact-less data acquisition
  • Frequency modulation and strain gauge principle cause high accuracy
  • Ordinary power supply
  • High interference rejection because of amplified active signal
  • Quick-release coupling
  • Short form, especially suitable for automatic screwing machines
  • Measurement, adjustment and examination without removing the screwing tool
  • Suitable for permanent use (even with higher speed)
  • Suitable for clockwise and counter-clockwise measurement

Suitable for

  • Automotive engineering
  • Test bench technology
  • Assembly technology
