The Series ADPS/EDPS 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/EDPS is available with settings from 0.08 in w.c. (20 Pa) up to
20 in w.c. (5000 Pa). The silicone diaphragm and PA 6.6 body make the series ADPS ideal
for use with air and other noncombustible gases. Series EDPS models meet UL508 and
are constructed of plenum rated plastics. The compact size, adjustment knob and low cost
make the ADPS/EDPS the perfect choice for HVAC applications.
