Hydrostatic level sensor CP5221

for water2-wire4-20 mA

The CP5221 is a precision submersible hydrostatic level sensor specifically designed for continuous level measurement, monitoring and control of liquids in tanks and clear water storage systems.

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 CP5221 features a 316L stainless steel body with PVC end caps and a 316L stainless steel sensing diaphragm. Its food-grade PVC cable sheath and submersible design allow direct installation in tanks.

With available measuring ranges from 0.5 to 30 metres of water column, it is particularly suitable for applications requiring the measurement of low liquid levels.
