VEGADIF 55
Differential pressure transmitter with metal diaphragm
Suitable for flow measurement in conjunction with effective pressure transmitters, level measurement on vessels as well as for detection of differential pressures for filter monitoring and pump control.

- Metal differential pressure measuring cell
- Simple local adjustment
- Fault monitoring of measuring cell and electronics
- Meets PED (Pressure Equipment Directive) standard
- Electronics can be exchanged without recalibration
