Series ADPS Differential Pressure Switch

Brand: Dwyer Instruments, LLC

The Series ADPS Adjustable Differential Pressure Switch is designed for pressure, vacuum, and differential pressures.

The dual scaled adjustment knob in inches water column and pascals allows changes to the switching pressure to be made without a pressure gauge.

The ADPS is available with settings from 0.08 in w.c. (20 Pa) up to 20 in w.c. (5,000 Pa). 

The silicone diaphragm and PA 6.6 body make the series ADPS ideal for use with air and other noncombustible gases. The compact size, adjustment knob and low cost make the ADPS the perfect choice for HVac applications.
Features
  • Adjustment know changes switching pressure easily with a pressure gauge reducing components for application
  • Low cost device makes it an excellent solution in BAS and HVac applications requiring duct control and monitoring
  • Relay contact allows simple integration with DDC or building systems
