The 267MR multi-range low differential pressure transducer from Setra boasts top multi-range ability. The transducer provides users with 6 selectable ranges and 2 selectable outputs that, by flipping the Dip Switch, can be easily configured. With a pressure range of 0.1” W.C to 100” W.C, the 267MR assures ±0.25%, ±0.4% and ±1% FS accuracy.
Designed and manufactured by Setra themselves, the capacitive sensing element is crafted from all stainless steel. The welded dead-ended capacitive sensors need only marginal amplification and dispense superior accuracy and long-term stability.
Versatility is a key feature of the 267MR, available in both wall and duct mounting options. The exterior of the 267MR is structured to sustain the most demanding work environments with its NEMA 4 rated housing, making the 267MR ideal for a variety of needs.
