VEGADIF 85

Differential pressure measurement for all media

With metallic measuring diaphragm


VEGADIF 85
VEGADIF 85

Application area

For applications with liquids in small containers under simple process conditions. Possible applications can be found in almost all industrial sectors.

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
