The MS8F is a single-pole, double-throw electric switch capable of sensing high or low liquid level inside a process vessel.
This switch has a stainless steel housing and is hermetically sealed and requires no maintenance.
The MS8F can provide either a normally open or normally closed dry contact to activate external devices such as alarms or solenoids.
Variations in process fluid specific gravity have minimal effect on the level measured because of the small size of the integral stainless steel float.
Electrical Contacts are Magnetically Isolated from Process
