Series 2-5000 Minihelic® II Differential Pressure Gage

Series AT-605 ATEX/IECEx Approved Magnehelic® Differential Pressure Indicating Transmitter

Series ADPS/EDPS Differential Pressure Switch

With Dual Scale Field Adjustable Set Point Knob

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.

Please see Series AT-ADPS for ATEX approved.
