Special Features

Small, compact housing

Tension sensor MZH-422 with integrated microprocessor controlled measuring amplifier and RS-422 interface for multi station system

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)

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
