ESMFS Double float ball water level switch , Water tank  high and low level  controller

Product working principle:

The float switch is a simple and easy-to-use liquid level control part. It has no complicated circuit and is not subject to interference. Usually it is placed in a closed metal tube or plastic tube, and one or more reed switches are provided. After that, one or more hollow floats with a ring-shaped magnet inside the reed pipe are fixed on the rod diameter, and are fastened to the position of the magnetic spring by a buckle, so that the float ball is in a certain range with the liquid level. The surface changes in height and floats up and down, using the magnet inside the float and the reed switch to generate magnetic field induction, so that it generates an open and closed action signal, and controls the liquid level.

Features:

1. Can do multi-point control, control switch can be customized with liquid level position
2. Reed switch does not need to provide separate power supply, the life of the reed contact is generally up to 2 million times.
3. Single float switch can do multi-point control, which is lower than the unit price of other liquid level switches.
4. High reliability, simple wiring, easy installation and more energy saving.
5. Plastic float switch is more suitable for chemical liquids such as acid and alkali sites.
6. PP material, non-toxic, food grade, suitable for foods, household appliances, etc.
7. PP+NBR float ball, which can withstand higher temperature, lighter weight and better performance.
8. PVDF material, suitable for oil medium, temperature resistance up to 120 degrees, acid and alkali corrosion resistance, compact and durable structure
