The CPC- 2 ET level sensor meets the requirements for explosion-proof devices and can be used as a group I device in category M1 and group II in category 1G and 1D.
The CPC-2ET level sensor is designed to control the level of liquids or liquid mixtures and to control pump switches or control devices using only 2 control wires. The sensor’s power supply as well as the control takes place through the same two wires from a device cooperating with a variable signal, eg 50Hz-133Hz and Ui = 40V. The device uses
a measurement method that eliminates electrolysis and thereby corrosion of the sensor probes in the liquid.
