The device Type 8181 is a float switch that is insensitive to dirt particles in the liquid

and is used to monitor the level in neutral or aggressive liquids in containers.

The device consists of a fixed part, which contains the hermetically sealed reed

contacts, and a float (moving part), which contains the magnets. This float actuates

the reed contact, which can be either normally open or normally closed, depending

on fluctuations in the liquid level.

The device is available in different versions depending on the material (PP or stainless

steel), installation position (horizontal or vertical), process connection (thread

G ⅛ G ¼, G ¾...) and electrical connection (leads or cable).
