The operation of COMECO’s level probe LCSFT is based on the switching of reed switches by magnetic floats, moving alongside a protective tube. Large variety of versions based on different stainless steel floats is available. 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 15 switching points and 5 floats can be mounted on a single probe, and the reed switches are capable of switching directly different loads. The probe is available with various aluminum and stainless-steel protective heads as well as ABS plastic enclosure. Various process connections are available as well as an options for vertical adjustment and temperature control.
