Series Description
The P32 Series Differential Pressure Switch is used to detect differential pressure or low positive gauge pressure in Building Automation Systems, BAS. Detection is achieved by using only the high pressure connection and leaving the low pressure connector open. It is also a vacuum detector, detecting vacuum by using only the low pressure connection and leaving the high pressure connector open to ambient pressure. The differential pressure switches are factory set at the bottom of their operating range with the diaphragm in a vertical plane. The setting will change if mounted in other positions. The P32AF has a close differential, and the P32AC has a standard differential.
