Description

The operation of the LCSF100 level transmitter is based on the switching of reed switches by a magnetic float, moving alongside a protective tube, and the reed switches act on the elements of a resistor matrix, changing the total matrix resistance in linear proportionality with the level measured. In addition to providing a 2-wire 4…20 mA output signal with 6 or 12 mm level resolution, the transmitter may be equipped with up to 2 alarm contacts. Moreover, LCSF100 can be equipped with an integrated loop-powered programmable indicator with independent alarm outputs. This level transmitter is very useful in applications where ultrasonic or capacitive transmitters would not work because of the foam, dense vapor, or non-homogeneous gas layer above the liquid surface.
