The level monitor is used to monitor the level or leakage of all conductive, non-flammable media. The response point can be set using a proportional potentiometer. As a monitor, the device works with an electrode (EO) and the ground connection (EM), e.g. for minimum or maximum messages, as overflow or dry-run protection for submersible pumps. If the surface of the level is unstable, an additional electrode (EU) is recommended. As a two-point controller, the device uses the electrodes EO, EU and ground connection EM to control pumps or valves for automatically filling or emptying containers. A container wall that conducts the medium can also be used as a ground connection. When connecting 2 electrodes, connections B2 and B3 must be bridged! Version: 230 V AC
