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 FS1-422 we offer different display units for one or more sensors, as well as strain gauge amplifier.
