AD-ER 01 GS

Description

The electrodes are supplied with alternating voltage. If a conduction liquid i.e. water, bridges the mass and the max-electrode, the output relay responds, the transmitter power monitor lights up. Furthermore an internal, commutator ensures that the min-electrode becomes effective. The relay de-energize, if the mass and the min-electrode are not conductive connected. The sensitivity can be adjusted to the given circumstances via an integral trimmer.
