Product Principle: 
 And small rod float level switch float level switch basically the same, usually sealed non-magnetic metal or plastic tube to set one or more points according to the magnetic reed switch, and then ring hollow and the internal floating magnet the ball of fixed diameter of the bar relative position within the magnetic reed switch, so that float up and down floating in a certain range, the use of the float magnet to attract the reed switch closure, resulting in switching to control the liquid level. Normally open and normally closed when there is no injection of the liquid state. Rod float level switch is set products, according to the measured fluid temperature, pressure, specific gravity, acid and other properties, select the appropriate size of the float. When you purchase need to determine the continuation specification (or threaded flange installation), the action point, movement in the form (normally open or normally closed) and the total length. 

 Features: 
 Reed switch contact materials rhodium (Rh surface oxide coverage), the contact life of up to 100 million times. Reed switches can make it special treatment temperature at 200 ℃ under normal use. Multi-point control can be achieved, the position of each control point can be customized according to customer needs. Overall reliable performance. Due to switch completely from the outside world, it has a long service life. 

 Material: 

 Stainless steel SUS304/SUS316 optional, customizable high temperature of 200 degrees, pressure 2.0Mpa, can control the electromagnetic valve, pumps, or for water protection, overflow alarm. Liquid level switch has a single point of control and multi-point control. 
 Level switches are built reed switch on the tongue and with a magnet in the float rod form, when the float along with the measured level / interface up or down, the float inside the magnetic field produced by permanent magnet reed switch driver action, to achieve switching. With explosion-proof, corrosion resistance and other characteristics.
