ELETTROSONDA Z 230V AC
Electric control liquid level relay, useful for controlling the minimum and maximum level of deep wells, tanks, cisterns, etc. It allows the maintenance of the liquid within established limits between a minimum and maximum level, also ensuring the protection of submersible pumps against dry running. The operating principle is based on the control unit detecting the resistance of the liquid, the level of which is controlled by means of special probes placed inside it. When the liquid level inside the container or well wets the three immersed probes, the relay is activated and deactivated only when the level drops and uncovers the low probe. Sensibility is a factory settings and is suitable for testing liquids with normal total resistance.
