Description
Dwyer ADPS-03-2-N Adjustable differential pressure switch, set point range 0.20 to 2.00" w.c., M20 connection.
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 gage. The ADPS is available with settings from 0.08" w.c. (20 Pa) up to 16" w.c. (4000 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.
