The operation of COMECO’s level probe LCSFK is based on the switching of reed switches by magnetic floats, moving alongside a protective tube. Large variety of versions based on different floats is available. The floats can be made of stainless steel or plastic; floats with different dimensions and specific gravity are available for liquid density down to 0.45 g/cm3, temperature up to 135 °C, and pressure up to 50 bar. Maximum 5 switching points can be mounted in a single probe, and the reed switches are capable of switching directly different loads. The wiring is attained with convenient detachable DIN connector. Various process connections are available as well as an optional vertical adjustment.
