  • 0-2.0″ W.C. precision air flow sensor
  • 18″ leads

The DP-1000-T is a high performance cost effective differential airflow sensor that precisely and repeatably measures 0 – 2 inches water column pressure and provides a proportional voltage output that spans 250mV to 4V. Power and signal connections are made fast and easy to Smart Controls programmable controller for fast and easy installation in air ducts, ventilation systems and other airflow applications.
