Setra 26910R1WB11BNGN Differential Pressure Transmitter

Setra 26910R1WB11BNGN is a Secure-Sense low-differential-pressure transmitter from Setra Systems that provides precise sensing of tiny pressure differences in HVAC, building automation, and process environments. It covers a differential range of 0 to 0.1 inH2O and operates on a supply voltage of 13.5 to 30 VDC, allowing direct integration into control loops without external translators or power supplies outside this range. As a member of Setra’s 269 family of differential pressure transducers, the model is designed for reliable monitoring of small pressure changes, offering a compact form factor and robust performance that aligns with typical HVAC/R applications. The 26910R1WB11BNGN is commonly used in HVAC installations to monitor pressure differences across filters and along air-handling paths, supporting proper air distribution and system diagnostics. By leveraging Secure-Sense technology, this transmitter provides stable, calibrated readings suitable for automatic control and monitoring networks, reducing drift and helping ensure consistent system performance over time.
