Static Pressure. Pressure can be defined as force per unit area that a fluid exerts on its surroundings. The basic physics of static Pressure (P), is calculated as force (F) divided by area (A). P=F/A. The Force can be generated by liquids, gases, vapours or solid bodies. The most commonly used pressure units are; Pa - [Pascal] in 1 Pa = 1 (N

The purpose of the Differential Pressure Switch is to sense a difference in pressure between two pressure sources in a control process. When the pressure from two different sources is connected across a sensing diaphragm, the pressure difference creates a force which then acts upon the pre-tensioned spring. This action moves a balancing arm or mechanism to effect the minimal movement required to activate the micro switch.
