MZ1-422
Tension Sensor

4 Tension ranges available
from 0 – 1000 cN up to 0 – 10 daN
Stationary electronic tension sensor for measuring narrow, parallel running threads, fibers and thin wires with a diameter up to approx. 2 mm

Universal sensors for continuous tension measuring in wire and textile industry

Tension sensor with RS-422 output for multi station system and connection to a with PC

Special Feature

  • Small, compact housing
  • Tension sensor MZ1-422 with integrated microprocessor controlled measuring amplifier and RS-422 interface for multi station system
  • Typical material path – warping the 3 rollers
  • Different guide rollers are available, according to the application
  • Easy installation, even afterwards, on existing machines
  • 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
  • Control lamp shows operative mode availability
  • Tension sensor MZ1-422 with aluminium housing
  • CAT 5 cables are used for data transfer
  • Required power supply +15…24 V DC (regulated)
  • Certificate of Compliance with the order 2.1 according EN 10204 is included
  • Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report

Special features of the RS-422 interface:

  • Up to 24 sensors with different tension ranges and designs may be connected in one line (data transfer max. 200 readings/sec.)
  • Connection to RS-232 using a converter (RS-422 – RS-232).
  • The RS-422 signal can be used for a single sensor over a distance of 1000 m.
  • Each sensor can individually be addressed and set up
  • Can be connected to PLC controls with digital input
  • Simple connection to BUS-Systems using gateways
