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)
– digital (optional): USB, RS-232, RS-422 – see model MZH-422
– 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

Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report

Other tension ranges and measuring head widths available on request.
Other measuring units available, such as g or kg.
* Outer dimensions of front plate
** Suitable for 95 % of applications PA = Polyamide Monofilament

Calibration to customized material:
If process material differs significantly from the SCHMIDT calibration material in diameter, rigidity or shape, special calibration using customer supplied samples is recommended. For this purpose a material sample of about 5 m should be supplied.

For the tension sensor MZH we offer different display units for one or more sensors, as well as strain gauge amplifier.
