The floating controller uses the buoyancy of the float and its own weight. The vertical push pin perpendicular to the liquid surface and the upper and lower positioning pins on the guide rod directly push and pull the FK1 type double throw bouncing switch and the FK2 type push button back switch. Pass and disconnect the liquid level control signal and the liquid level over-limit alarm signal.
The floating controller uses the buoyancy of the float and its own weight to directly push and pull the FK1 double-throw bouncing switch and the FK2 type push button back-back switch through the vertical and horizontal positioning pins on the guide rod and the guide rod perpendicular to the liquid surface, thereby turning on and Disconnect the subsurface control signal and the subsurface over-limit alarm signal.
1. This structure is to directly push and pull the contact switch with the buoyancy and self-weight of the float ball. It can directly switch the relay, solenoid valve, contactor and phase electric appliance without the semiconductor component and the amplifying circuit. The maximum switching power can reach 2KW. Extremely reliable and long lasting, it can be used for more than ten years.
2. The switch box is explosion-proof and waterproof, fully enclosed, and is not affected by corrosive gases and harsh environment. The switch box will not enter water at 3 meters deep water.
3. The maximum operating voltage of the annunciator switch is 380V, and the maximum working current is 5A. (220V10A).
4. Made of high quality copper and stainless steel metal, it has high strength, acid resistance, alkali resistance, salt resistance, oil resistance, water resistance and temperature resistance (maximum working temperature 110C).
5. Water level control uses only one switch, two signal lines are controlled, simple and reliable.
6. FKI type is normal liquid level control; FK2 type is upper and lower over limit alarm.
