VEGADIF 85
Differential pressure measurement for all media
With metallic measuring diaphragm
Application area
For level measurement in superimposed pressure vessels and flow measurements in combination with effective pressure transducers. Further applications are pressure monitoring of filters as well as density and interface measurements.
The VEGADIF 85 is a universal differential pressure transmitter for measurement of liquids, gases and vapours. Typical application areas are level measurement in pressurized vessels as well as flow measurement in combination with effective pressure transmitters. Further applications are pressure monitoring on filters as well as density and interface measurements.
Your benefit
- High reliability through integrated overload diaphragm
- Measurement of very low differential pressures through high precision measured value detection
- Multivariable sensor through integrated measurement of the absolute pressure
