Level Sensors

HydroBar G II

Part No. HSB0 HG

Screw-in with capacitive ceramic measurement cell

Screw-in probe with internal 4 - 20 mA transmitter for hydrostatic level measurement in water, wastewater and gases. Oil-free capacitive ceramic measurement cell.

[Translate to English:] HydroBar G II – zur hydrostatischen Füllstandsmessung

Robust and reliable screw-in probe with 1.5“ threaded connection
Capacitive ceramic measurement cell
for slight to heavily polluted liquids, sludge and pasty media
Large front-flush diaphragm
2-wire probe
Ex Zone 0
High overpressure resistance
Integrated overvoltage protection

The hydrostatic level probe with G 1.5” thread has been developed to meet the high demands of industry and environmental protection.

The corrosion-proof encapsulation featuring IP68 protection rating allows to use the unit for reliable level detection in containers, tanks and pipelines. The large resistant ceramic diaphragm has proven particularly in the wastewater sector as well as in the chemical industry. Due to the front-flush diaphragm the unit can be used even in viscous media and pastes. Diaphragm failures are virtually eliminated.The HydroBar G II can be used in aggressive media such as acids and caustic solutions as well.

Utilising the widely used 2-wire technology, the installation costs are very low.The unit is optionally available with a 4-character LCD integrated into the enclosure lid for indication of measurement values.
