Pressure signaling device universal (SDU-M) - a signaling device that reacts to pressure changes by closing/opening the contact group, as a result of which a signal is issued about the ingress of GOTV into the piping or the outlet device of the UV when the MPG module is r.v.

The signaling device is designed for round-the-clock operation, designed to work indoors, but can be used outdoors if it is installed in places protected from solar radiation and precipitation.
