Model 267MR Low Differential Pressure Transducer

Brand: Setra Systems, Inc

Setra’s Model 267MR is a highly configurable multi-range 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% Full Scale accuracy options with pressure ranges from 0.1” W.C. up to 100” W.C.
