These high-quality differential pressure gauges are notable for their compact and robust design and are primarily used for level measurement on liquid gas tanks. With 6 different measuring cells, all usual tank sizes in cryotechnology are covered. The large overlap in measuring ranges of the measuring cells enables the setting for gas types such as Ar, O2, N2 or CO2 over the entire scale with 270 angular degrees. The span adjustment is accessible from outside and does not affect the zero point.
The mechanical display and the integrated transmitter with 4 … 20 mA output signal (optional) are calibrated simultaneously and easily. An optional valve manifold for flange mounting makes the central level measurement and working pressure indication possible in the one instrument.
Switch contacts for level and working pressure, as well as a transmitter for the working pressure can be retrofitted on-site. The standard centre distance of 37 mm between the process connections can be adapted to a custom centre distance of 31 mm or 54 mm using adapters for flange mounting.
