The Setra 267 is a very low differential pressure transducer, built to be configurable rather than locked to one range or accuracy class. It covers 0.01 to 100 in. W.C., with your choice of ±0.25%, ±0.5%, or ±1% FS accuracy, so it fits jobs ranging from very fine cleanroom pressure differentials up to more general HVAC duct pressure work.
In actual application, the sensing element is a welded, dead-ended capacitive sensor, built from stainless steel and manufactured in-house by Setra rather than outsourced, which is part of why it holds accuracy over time. It runs on 24VAC or 24VDC excitation, and wiring comes in through PG-9, PG-13, or conduit terminations depending on what your panel uses.
From our experience, the NEMA 4 rated housing is genuinely useful outside of cleanrooms and hospitals too, it shows up in natural gas and pipeline monitoring and downhole ventilation work where the enclosure needs to handle a rougher environment. It’s available as wall mount or duct probe, with an optional integral static pressure probe (0.25-inch aluminum), and an optional LCD display if you want a local readout.
Before we quote this, we would normally check your pressure range, accuracy class, and whether you need the display or static pressure probe options. Hope this helps.
