MZH
Tension Sensor

7 Tension ranges available
from 0 – 1000 cN up to 0 – 100.00 daN
Stationary electronic tension sensor for narrow, parallel running flexible material as wires, thin ropes and cables up to 15 mm Ø, as well as linear, flat material up to 10 mm width

Large, hardened guide rollers for minimized material deflection

Tension sensor for quick and easy mounting

Special Features

  • Small, compact housing
  • Tension sensor MZH with integrated measuring amplifier and high accuracy of 1.5 % FS
  • Typical material path – warping the 3 rollers
  • Ball-bearing mounted guide rollers,
    – V-grooved (for material with max. 4 mm Ø)
    – U-grooved (for material with 3 up to 15 mm Ø)
    – tape grooved (for material with max. width of 10 mm)
  • Various output signals are available:
    – analog: 0 – 1 V DC (standard), 0 – 10 V DC (optional)

    – current: 4 – 20 mA (optional)
  • Universal mounting possibility – easy to install, even afterwards, on existing machines:
    The sensor can be mounted using the two threads at the underside of the housing body. Alternative it can be fixed on two flanges on the side of the unit.
  • Easy calibration to customized material by operator – zero and gain calibration is required
  • Measuring principle – load cell with high quality strain gauge bridge

Standard Features

  • V-grooved guide rollers, ball-bearing mounted
  • Required power supply +15…24 V DC (regulated)
  • Certificate of Compliance with the order 2.1 according EN 10204 is included
