Setra 267 Data sheet

Model 267

Very Low Differential
Pressure Transducer

Setra’s Model 267 is the most rugged high accuracy, low dier­ential pressure transducer on the market. It delivers accuracies
of ±1% FS (without display), ±0.5% FS (with display), and op­tional ±0.25% FS and ±0.4% FS accuracies, and pressure ranges
from 0.1” W.C. up to 100” W.C. The 267 is housed in a robust,
NEMA 4 rated enclosure and has an optional static pressure
probe reducing installation and material costs. The 267 is of­fered with an optional LCD display and a standard accuracy of
±0.5% making it ideal for high accuracy Pharmaceutical appli­cations.

Customization is Standard

The 267, unlike most competitors, oers many mechanical and
electrical options that can be integrated into existing designs.
The optional 0.25” diameter pressure probe is made of sturdy
extruded aluminum and is designed with baes to prevent ve­locity pressure errors which saves money and reduces time on
the job site.

Robust Enclosure for Difcult Applications

The 267 is housed in a NEMA 4 rated housing and is built to
withstand harsh environments. The 267 is available in both
wall and duct mount providing the installer with exible
mounting options. The wall mount allows the sensor to be
installed anywhere, whereas the duct probe conguration is
designed to maximize space eciency in dicult applications.

The Setra Sensor

The core technology of the 267 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 amplication and delivers
excellent accuracy and longterm stability. Setra’s technology
has been used in over 8 million installations and has the high­est eld acceptance rate in the industry.
