The Dwyer ADPS-05-2-N-C is the installer-kit version of the popular ADPS HVAC differential pressure switch, supplied with two plastic static pressure tips and seven feet of PVC tubing so the switch can be plumbed and commissioned out of one box. It covers a setpoint range of 0.80-4.00 in WC (200-1000 Pa), uses a silicone diaphragm and SPDT relay output, and is field-adjusted with a dual-scaled knob (in WC and pascals) that lets a technician set the trip point without a separate manometer. Electrical entry is via M20x1.5 cable gland, and the housing is rated NEMA 13 (IP54) for typical HVAC indoor installation. The ADPS-05-2-N-C is CE marked for general HVAC use, and is rated for air and other non-combustible, non-aggressive gases only.

Key Features
Dual-Scale Field-Adjustable Knob
Setpoint is dialed in with a labeled knob graduated in both inches WC and pascals. Technicians can commission the switch without a separate digital manometer, which cuts installation and balancing time on large jobs.
Compact 4.4 oz Form Factor
Switch weighs just 125 grams and mounts directly to wall, sheet metal, or via the optional A-288 L-bracket or A-289 S-bracket. The base also accepts snap-on rail clips, so the same SKU works for permanent installs and quick service replacements.
SPDT Relay for BAS/DDC Integration
Single-pole double-throw relay rated 1.5 A resistive / 0.4 A inductive at 250 VAC. Common, normally-open, and normally-closed contacts are available on push-on screw terminals - drops straight into DDC, BAS, or stand-alone control wiring.
Three-Side Cable Entry
M20x1.5 cable gland with integral strain relief can be installed at any of three housing positions, which lets the installer route cable from whichever side keeps the run cleanest. Seal accepts 7 mm or 10 mm cable sheaths.
Long Mechanical Life
Silicone diaphragm and over 1,000,000 mechanical switching operations rated. The switch is designed for continuous duty in HVAC service with no scheduled maintenance beyond periodic calibration checks.
Installer Kit Included
Ships with two plastic static pressure tips and seven feet of PVC tubing - everything needed to plumb the high and low ports into a duct or AHU on the same delivery, no separate accessory order required.
