Stationary electronic tension sensor for measuring tensions of narrow, parallel running threads, fibres and thin wires with a diameter up to approx. 2 mm

Universal sensor for continuous tension measuring in wire and textile industry with different output signals

Tension sensor for quick and easy mounting

Special Features

  • Small, compact housing
  • Tension sensor MZ1 with integrated measuring amplifier and high accuracy of 1.5 % FS
  • Typical material path – warping the 3 rollers
  • According to the application, different guide rollers are available
  • Various output signals are available:
    – analog: 0 – 1 V DC (standard), 0 – 10 V DC (optional)
