Product Description

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 AT1ADPS for ATEX approved.

FAQ

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
Will a Dwyer pressure switch be damaged if the pressure exceeding the maximum set-point is applied to the switch?
Answer
No. Not unless the maximum pressure rating of the switch is exceeded.
