Designed for Liquids with Adjustable Setting
A differential pressure switch is an electromechanical device used for sensing a difference in pressure between two points.
Application of Differential Pressure Switch 908
Adjustable differential pressure switch monitoring overpressure, vacuum or differential pressure of liquid and gaseous – also aggressive – media.
The differential pressure switch uses an adjusting screw to enable the adjustment of the switching pressure.
Class of control and regulation function: A
