Features
Features- Reed switch makes 10 million times use possible.
- Applicable to many different liquids as SUS304 (SUS316, SUS316L) and corrosion-resistant resin are used for the wetted surface.
- Lots of operations are selectable. Multiple points are detectable by adding the number of reed switches.
- Not affected by moisture, gas, dust etc.
- Easy handling with simple structure.
- Exd II BT4 certified flame proof available.
(KFE-3000 series)
Operating Principles
Float contains magnet and the stem contains reed switch. UP/DOWN movement of the liquid surface makes the reed switch ON/OFF with the magnet inside the float. The stoppers at the top and the bottom of the float limit the movement range and keep the self holding of the contact operation.
