This hollow float is lifted by the rising liquid and pushed upwards until a start process is triggered when an angle of 50° to the horizontal is reached. The float can be fixed by screwing it to the side or, if the tank is open, by placing it above the liquid. The standard ballast weight allows the switching point to be set very precisely. Suitable for almost all pumps. The float is very suitable for checking the level of any liquid that does not attack its material, regardless of the degree of contamination. You can use this float switch as a full or empty indicator, to control pumps or valves, or other alarm signals. If your pump has an output power greater than 1.1 kW, you must connect a standard commercially available socket or a power relay. A 380 V electrical connection can operate a 380/400 V three-phase pump. Application / Information / Properties If your pump has an output power greater than 1.1 kW, you must connect a standard power contactor or a corresponding power relay.
