The Setrea 265 Low Differential Pressure Transducer is a cost efficient choice to meet all the requirements in standard HVAC applications. The transducers employs a dead-ended stainless steel capacitive sensing element that demands little amplification and provides precision accuracy and lasting stability. It is capable of ±0.25%, ±0.4% and ±1% FS accuracy options with pressure ranges from 0.25” W.C. up to 100” W.C. The 265 comes equipped with an AC power option, integral mounting tabs, pressure connections on the face of the unit and a screw terminal strip for electrical termination.

The Setra 265 uses revolutionary technology with its all stainless steel capacitive sensing element.
