Plastic Level Sensor | LMK807 | Flush-Mounted | Low Cost

Ø35mm, Plastic & Flush-Mounted for Sewage Level Measurement


The LMK807 plastic level sensor is low cost and ideal for sewage, sludge and other aggressive media, thanks to its flush-mounted ceramic sensor element.  The flush mounting means any solid parts of the viscous media can be easily cleaned from the sensor.  Various cable and elastomer materials are available to achieve maximum media compatibility.

It has a diameter of 35mm and measures in media from 0-4mH20 up to 0-100 mH2O.

The LMK807 plastic level sensor can be offered with SIL 2 (safety integrity level) according to IEC 61508 / IEC 61511.

Alternatively, try our stainless steel wastewater level sensor with a slightly wider diameter of 39.5mm with a measuring range of 0-40cmH20 up to 100mH20.

Need a narrower water level sensor?  Try our LMP307 water tank level sensor which has a diameter of Ø26.5mm and can measure from 0-1mH20 up to 0-250mH20.
