- 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

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.
