Hydrostatic level sensor CP5218

for waternatural water2-wire

The CP5218 is a submersible hydrostatic level sensor designed for continuous level measurement, monitoring and control of liquids in demanding environments, particularly in wells and boreholes.

With its 18 mm diameter and 316L stainless steel construction, it is suitable for installations requiring a compact and robust sensor. 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.

Its 316L stainless steel diaphragm features a flexible protective coating. The sensor has an IP68 protection rating, allowing immersion up to 1.5 times its full-scale measuring range.
