The Setra Model 264 is a very low differential pressure transducer used a lot in HVAC building automation and energy management systems, especially where you need to hold a tight static pressure or airflow reading over the long term. At the core of it is an all-stainless steel, dead-ended welded capacitive sensing element, so there’s no diaphragm fluid to worry about and no risk of cross-contamination between the process gas and the sensor.
In actual application, this unit is built for clean, non-conducting gas media and comes with brass barbed fittings for quick field tubing connections, plus a choice of wall mount or conduit mount styles depending on how your panel is laid out. It runs on a low-cost, unregulated DC power supply and puts out either a 4-20mA current loop or an analog voltage signal, so it should drop into most existing BAS wiring without much fuss.
From our experience, this is the transducer people reach for when they need long-term stability on VAV box control, cleanroom pressure monitoring, or static pressure tracking – the kind of application where drift over months and years actually matters, not just the accuracy on day one. It’s also backed by a 3-year warranty, which tells you Setra is confident about long-term performance.
Before we quote this, we would normally check the exact pressure range you need (unidirectional or bidirectional), the output signal type your BAS controller expects, and whether you need the standard or a higher accuracy tier. Hope this helps.
