Omron 61FGPN8220AC, 61F-GP-N8, Conductive Level Controller DIN Rail 220 Vac

The device features a plug-in controller that connects to a pair of electrodes, which can be set to the desired level. These are dropped down into conductive liquids at a low 8V AC voltage that creates an electrical current when it makes contact with the water. Once liquid levels dip below the set level of the electrode, the controller de-energises with a fast release time of 160ms. Use this device to monitor liquid levels and detect leaks to ensure your pumps don't run dry.
