SOR 090A Pressure Switch

Feature & Principle

It is a mechanical pressure control switch. The process pressure acts on the internal sensing diaphragm assembly. When the pressure reaches the preset threshold, it triggers the snap-action micro switch to output dry contact on-off signal. The set value can be adjusted on site, no external power supply required for sensing part, stable action and small dead band, used for high / low pressure alarm and equipment interlock protection.
