Hydrostatic level sensor CP5219

for waternatural water2-wire

The CP5219 is a submersible hydrostatic level sensor specifically designed for continuous level measurement, monitoring and control of liquids in wells, boreholes, dams and demanding environments, particularly in thermal or oxidizing waters.

Its 316L stainless steel body and FEP-sheathed cable make it suitable for use under demanding operating conditions. Its piezoresistive sensing element measures the hydrostatic pressure exerted by the liquid column and converts it into a 4–20 mA, 2-wire analog signal, proportional to the measured level.

The CP5219 is also available, on request, with an inverted 20–4 mA output signal, allowing level measurement referenced to ground level.
