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.

Questions

Question

EDPS series, can the 'delta-P' screw be used to increase or decrease deadband?

Answer

The ∆P screw should never be adjusted. It is used to calibrate the instrument to make sure it will switch within the specified range.

Question

We have been using ADPS-08-2-N-C in our standard systems. We now have a requirement for the switch to work with air with some Ozone content. Any suggestions on what model to use?

Answer

For a low-range pressure switch, the Series ADPS is a very good solution for Ozone.
