Applications
* Level measurements in closed tanks, particularly in cryotechnology
* Filter monitoring
* Pump monitoring and control
* For gaseous and liquid media that are not highly viscous or crystallising and have no suspended solids
Special Features
* Differential pressure measuring ranges from 0 … 40 mbar to 0 ... 4,000 mbar
* High working pressure (static pressure) of 50 bar
* Overpressure safety either side up to 50 bar
* Scalable measuring ranges (maximum turndown of 1 : 3.5)
* Compact valve manifold with working pressure indication (optional)
