New differential commercial pressure switch

Winters Instruments’ new WPS Series is a low-pressure differential switch for monitoring and controlling air and non-aggressive gases. THE WPS Series has been developed to handle pressure, vacuum, and differential pressures, making it perfect for HVAC applications and very easy to integrate into BAS systems. 

The user-friendly adjustment knob enables field changes to be made with no need for a reference pressure gauge. The device’s sensitive silicone diaphragm can sense pressure as low as 0.08 inches/2mms of water (16 Pa) up to 20 inches/508 mms of water (4,000 Pa). The WPS Series’ is compact with a simple and effective adjustment knob and competitive cost; it is therefore the ideal solution for every commercial application.
