Differential pressure transmitter VD85

Type VD85

Differential pressure transmitter with metallic measuring diaphragm

 

Application Area

For applications with liquids in small containers under simple process conditions. Possible applications can be found in almost all industrial sectors.
 
 
The differential pressure transmitter VD85 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
