Magnetic Float Level Sensor

Model : MFS 100 – Single Level  / MFS 200 – Two Level

Electronic Switches ( I ) P. Ltd; offers range of Magnetic Float Switches. These are mainly available for Single Level Sensing and Two Level Sensing type. Magnetic Float Switch contacts are SHORT when float is at lowermost level and OPEN when float moves up (towards fixing). As per the level of liquid, float position changes and corresponding output is used for automation Control Unit is also available for automatic functioning of Pump or Feeder with supply 220 volts AC and offers relay output. Relay is ON when level of liquid reaches lower level and gets OFF when level of liquid reaches upper level.

This can be used for further interlock for automatic functioning of system. Control Units also offers audio or visual alarms. Float Switches are used for sensing the level of liquid in storage tanks, reservoirs, hoppers, and are ideal for automatic pump control, audio and visual alarms, & safety interlocks.
