The Differential Pressure Switch is a pressure and flow monitor switch, when the water flow (differential pressure) in system rises up or falls down to set value, it will activate a relay signal to automatic control system. It could be calibrated directly by manufacturer according to customer’s requirement, and printed the calibrated value on the label of product, so user needs not readjust in the site. The customer could calibrate by professional instrument according to the differential pressure required by equipment.
The dual adjustable differential pressure switch with two setpoints also enables the filter to achieve high and low differential pressure control, over-pressure protection, backup differential pressure control, etc.
The Differential Pressure Switch with high precision and reliability is an ideal control unit for automatic backwash filter, pump or water filter and differential pressure detection of central air conditioning.
