The Dwyer 2-5002 102332-00 Differential Pressure Switch is a compact device that activates an electrical output when the sensed differential pressure crosses a set threshold. It is specified for 30 PSI and a differential sensing range of 0–2.0 inWC, with NSMP noted in the product details. This differential pressure switch provides a straightforward means to monitor pressure differences and control or alarm circuits when the threshold is reached.
