The LMK382 wastewater level sensor has a diameter of 39.5mm and is designed to measure in wastewater, sewage and higher viscosity media from 0-40cmH20 up to 0-200 mH2O.  It can also be used drinking water abstraction.

The LMK382 wastewater level sensor is constructed of high-quality stainless steel offering good long term stability, along with a ceramic sensing element.

IS-versions and Ex ia = intrinsically safe for gas and dust versions are available to measure pressure in extreme environments.
