Special Features

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
