SERIES ADPS/EDPS DIFFERENTIAL PRESSURE SWITCHWith Dual Scale Field Adjustable Set Point KnobThe 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. Please see Series AT-ADPS for ATEX approved. PRODUCT APPLICATIONS- Monitoring air filters and ventilators.
- Monitoring industrial cooling-air circuits.
- Overheating protection for fan heaters.
- Monitoring flows in ventilation ducts.
- Controlling air and fire-protection dampers.
- Frost protection for heat exchanges.
