Magnetic Level Switch HM (microswitch)




Side mounted alarm control applications of bilge tanks and oil tanks


  • Insensitive to process conditions such as pressure, temperature and specific gravity
    • Unlike other technologies, FM offers reliable measurement without being affected by temperature, pressure, specific gravity, capacitance or conductivity.
  • A wide range of wetted parts materials and designs available
    • Available in various materials and designs to suit virtually any applications. Interface detection is also available.
  • High reliability
    • Among high accuracy reed switches, only those that meet our original standards are used to ensure stable operation over the long service life.

Principle of Operation

Principle of Operation   The shaft has a magnet at the end and the stem has a reed switch. The reed switch opens or closes to indicate liquid presence as the liquid surface rises or falls.
