Arrangement for the interrogation of a critical filling level or a limit level, there in a tank

摘要

Arrangement for the interrogation of a limit level, there in a tank 4 with a capacitive limit level switch 2 in an elongate housing with three measurement electrodes 1, which in the two end regions and in the center area of the elongated housing are provided, wherein the measurement electrodes 1, via a multiplexer mux are connected to an evaluation unit μc, a radio - communication module 3 and a battery 8 is present, the elongated housing of the capacitive limit state switch 2 perpendicularly to the outer wall of the tank 4 is to be attached, wherein the limit level switch 2 via a mobile phone 7 can be activated from a rest state, wherein, after activation of the evaluation unit μc of the covering state of the measurement electrodes 1 via the multiplexer mux can be interrogated successively in time.n="10"
