Dwyer Instruments ADPS-03-2-N | Differential Pressure Switch | 1/4 NPT | Set Pt Range 0.2-2 In. WC | ADPS Series
The Series ADPS/EDPS Adjustable Differential Pressure Switch is engineered to handle pressure, vacuum, and differential pressures with ease. Its dual scaled adjustment knob, measuring in inches water column and pascals, facilitates precise adjustments to the switching pressure without the need for a separate pressure gauge. With settings available from 0.08 in w.c. (20 Pa) to 20 in w.c. (5000 Pa), it offers versatility to suit various pressure requirements.
Crafted with a silicone diaphragm and PA 6.6 body, the Series ADPS is specifically designed for compatibility with air and other noncombustible gases. Meanwhile, the Series EDPS models, meeting UL508 standards, boast construction from plenum-rated plastics, ensuring safety and reliability in a variety of environments.
Thanks to its compact size, user-friendly adjustment knob, and cost-effectiveness, the ADPS/EDPS series is an ideal choice for HVAC applications, delivering reliable performance without compromising on quality.
