Airflow sensing range:

DXA.S04P1 and DXA.S04P1-B: 250 Pa (0…1” WC)

DXA.S04P2 and DXA.S04P2-B: 500 Pa (0…2” WC)

Accuracy: 1% of reading or 0.25 Pa (0.001” WC), whichever is greater

Normal operating range:

DXA.S04P1 and DXA.S04P1-B: 0...250 Pa (0...1" WC)

DXA.S04P2 and DXA.S04P2-B: 0...500 Pa (0...2" WC)

Over-range detection: The APS provides a separate over-range detection allowing the controller to perform the correct action at a higher airflow.

DXA.S04P1 and DXA.S04P1-B:

  • 250...274 Pa (1...1.1" WC) : over normal operating range; still supported from the device
  • above 274 Pa (1.1" WC): value is out of range
  • above 24,000 Pa (96" WC): may cause equipment damage

DXA.S04P2 and DXA.S04P2-B:

  • 500...550 Pa (2...2.2" WC) : over normal operating range; still supported from the device
  • above 550 Pa (2.2" WC): value is out of range
  • above 24,000 Pa (96" WC): may cause equipment damage

Under-range detection: The APS provides a separate under-range detection allowing the controller to perform the correct action at a lower airflow.
