The level sensor BLCSFT is based on the switching of reed switches by a magnetic float, moving alongside a protective tube. Large variety of versions based on different floats is available. Floats can be made of stainless steel or plastic; floats with different dimensions and specific gravity are available for liquid density down to 0.5 g/cm3, media temperature up to 140 °C and pressure up to 30 Bar. Maximum seven switching points and five floats can be mounted on a single probe. The wiring is available with type “B”, “G”, or EEx d aluminum protective head, or ABS plastic enclosure. The reed switches are able to switch directly different loads. Various process connections are available on request as well as a vertical adjustment option. In case of Ex applications, an intrinsically safe remote unit must be used.
