Magnetic Level Switches
- Contact: max. 4 reed switches
- Connection: G ⅛ … G 2 male thread, flange DN50 … DN125, 1½ … 4″
- Material: brass, stainless steel, PVC-U, PP, PVDF, NBR
- pmax: 100 bar
- tmax: 150°C

Kobold magnetic float switches are fitted with a hermetically sealed contact which is situated in the tube.
The float sliding on the tube contains a ring magnet whose magnetic field switches the sealed contact in a non contacting fashion. The sealed contacts are available as N/O, N/C or changeover contacts.
The float sliding up and down on the liquid is the only moving part in the Kobold magnetic float switches.
Applications
Magnetic level switches are used for the monitoring and control of liquid levels in vessels. Magnetic level switches are manufactured to customer specification.
