The 267 multirange low differential pressure transducer from Setra offers accuracies of ±0.25%, 0.5% and ±1% FS across an expansive pressure range of 0.1” W.C. up to 100” W.C.
Unlike other competing transducers, the 267 is built on the principle of customization, offering a myriad of electrical and mechanical options that can be applied to the standing design. 0.25” diameter pressure probe options is crafted from extruded aluminum and, in combination with baffles, prevents velocity pressure errors providing for faster and more cost effective work methods.
The physical construction of the Setra 267 makes it ideal for a variety of demanding applications. The NEMA 4 rated enclosure is built for the toughest environments. Available in both a wall and duct mount, the 267 can be installed anywhere with the wall mount and can maximize space efficiency with the duct probe configuration.
The Setra 267 uses the advanced technology of an all stainless steel capacitive sensing element. With all the sensing elements designed and manufactured by Setra, each sensor comes with the promise of upmost quality. Setra’s technology has been applied in over 8 million installations and proudly carries the highest field acceptance rate in the industry.
The combination of top quality technology, versatility and customization all in a resilient physical construction, make the Setra 267 one of the leading multirange low differential pressure transducers available.
