This water pressure differential switch is for measure liquid pressure of a center air condition system or an industrial process. It helps an operate administrator to know pressure status and to control of ice water pump, cooling water system frequency conversion control or boiler system pressure control.
【Features】
This switch combines an "EPDM diaphragm isolates pressure chamber" and a "limit switch". The magnetic force driven the limit switch, This feature makes the device not leak water and last for a long time.
The limit switch is driven by magnetic force, has no direct water contact, so has no leak problem.
