The Model 267MR is Setra’s most highly configurable multirange low differential pressure transducer. It offers multi-range capability with 6 field selectable ranges and 2 field selectable outputs that are easily configured by flipping a Dip Switch. The 267MR is housed in a NEMA 4 rated enclosure with an optional static pressure probe reducing installation and material costs.  It delivers ±0.25%, ±0.4% and ±1% FS accuracy options with pressure ranges from 0.1” W.C. up to 100” W.C.

All Inclusive Field Selectable Design - The 267MR is the ideal product for any contractor to stock in their truck; combining the flexibility of a multi-range with the performance of a single-range transducer to ensure the installer has the right solution for any job.

Robust Enclosure for Difficult Applications - The 267MR is housed in a NEMA 4 rated housing and is built to withstand harsh environments.  The 267MR is available in both wall and duct mount providing the installer with flexible mounting options.  The wall mount allows the sensor to be installed anywhere, whereas the duct probe configuration is designed to maximize space efficiecny in difficult applications.

The Setra Sensor - The core technology of the 267MR is the all stainless steel capacitive sensing element. Setra designs and manufactures all of their sensing elements resulting in full control over the process and quality of every single sensor. The welded dead-ended capacitive sensors requires minimal amplification and delivers excellent accuracy and longterm stability. Setra’s technology has been used in over 8 million installations and has the highest field acceptance rate in the industry.
