Setra Systems 2651025WD2BT1E is a Model 265 very low differential pressure transducer that measures 0 to 25 inches water column (in. wc) and provides a 0 to 5 VDC output when powered from a 24 VDC supply. Built on Setra's capacitive sensing technology, it delivers stable, long‑term differential pressure readings suitable for HVAC airflow monitoring and building automation. This fixed‑output variant is commonly used in air‑handling units, duct monitoring, and other low‑pressure sensing roles where compact size and straightforward interfacing are valued.
