Side mount type ball float liquid level switch is introduced:

Product principle: usually will seal nonmagnetic metal or plastic tube according to the need to set up amagnetic reed switch, then hollow an internal ring magnet ball float fixed on the magnetic reed switch related position in stem diameter, the proportion of floating ball is smaller than the liquid density, liquid float float up and down within a certain range, using the floating ball in the magnet to attract the magnetic reed switch is closed, the switch action, to control the liquid level. Often there is no injection liquid when opened and closed state.

Product features: side small ball float liquid level switch is a kind of simple structure, convenient use of level control parts, it has complex circuit, not disturbed, as long as the material of choice is correct, you can use on any properties of liquid, pressure, temperature.

Magnetic reed switch contact materials for rhodium (rhodium oxide surface cover), contact life can reach 2 million times.

Special treatment, magnetic reed switch can make its normal use under the high temperature of 200 ℃.

Float switch, the overall performance is reliable, a variety of materials and specifications are available.

 

 

Liquid medium properties and floating ball relationships:

 

1. The proportion of liquid, and at the same time, the floating ball action position will change, generally SG hours than water, floating ball dipped in the liquid part will be relatively increased.

 

2. The proportion of float switch product to use as a reference to water (SG = 1) so when using the proportion that must be taken into consideration when choosing ball float liquid level, SG, must be greater than the floating ball specifications marked,

Otherwise, the float switch can't float.

3. High won't dry liquid viscosity, generally should choose diameter larger floating ball.

4. The float switch is to use magnets to induction magnetic reed switch, so the measured liquid level should be no iron filings, otherwise it will affect the float switch action team.
