Slimline plastic level sensors for waste water and other aggressive media

With a diameter of 21mm, the LMK 806 series of PVC-housed submersible ceramic level sensors is specially designed for hydrostatic level measurement of wastewater and other aggressive media, particularly where the sensor needs to be mounted inside a confined space such as an existing small size borehole, ¾in pipe or tube.

LMK 806 level sensors benefit from a PVC housing that provides maximum media compatibility and protection from virtually any aggressive media, including most acids and strong alkalis. Different cable materials and seals are available to suit a range of different media.

The sensing technology on the LMK 806 series is a flush-mounted ceramic sensing element, which provides high reliability in long-term installations. Reliability is further enhanced by a nose cone, which when removed, exposes the flush diaphragm. This allows the sensor to be easily cleaned and any solid media removed, thus preventing clogging.

Nominal pressure ranges are from 0-6mWG up to 0-200mWG. Accuracy is +/-0.5 percent FSO to IEC 60770 and so includes all setting errors, making this a high accuracy level-measuring instrument.

The sensor provides excellent linearity, long-term stability and a high level of electrical protection (emission and immunity according to EN 61326) to prevent damage once the unit is installed in the field. Output signal is 2-wire, 4-20mA.
