Overview:
The differential pressure switch is designed for OEM customers to control flow accurately. It is designed to be a compact,cost-effective differential pressure switch for applications involving hot or cool air ,proof-of-flow,filter monitoring etc. It provides an output when a pre-set difference is exceeded. The set point can be easily modified. The value can set by our professional according to customer’s requirement and print on the label. Differential pressure flow switch with adjustable set point in HVAC system has the same performance with fixed set point switch, they are substitute of target flow switch.
