Conductivity Type Level Switch

We offer conductivity type level switch. The electronic circuit of a level control unit is connected to one electrode and to the wall of metal or steel container. Once the liquid in the container has reached the level of electrode, the control circuit between electrode and container wall is closed via the electrically conductive liquid there by activating the output relay. The control circuit is galvanically isolated from the mains by an isolating transformer and thus the use of an additional electrode is eliminated.
