Setra Systems

Low pressure measurement is where Setra Systems made its name. The company, founded in 1967 and based in Boxborough, USA, builds pressure transducers for building air systems, clean spaces and industrial equipment. Seven Star LLC, an independent supplier in Oman, lists the Setra 264 low differential pressure transducer, the Setra 267 very low differential pressure transducer and the Setra 209 pressure transducer.

The 264 and 267 measure small air pressure differences, the kind found across a filter, between two rooms or in a duct. The 267 comes in a NEMA 4 housing for wall or duct mounting, with an optional static pressure probe and LCD, and both are ordered by range, unidirectional or bidirectional span and output signal. The 209 is a different instrument: a compact pressure transducer for industrial and refrigeration equipment. The 264 and 267 use Setra’s stainless steel capacitive sensing element.

Ordering Setra transducers: what we need

Setra part numbers are long because each character fixes a feature. Copy the full number from the label. If the label is gone, send the model (264, 267 or 209), pressure range and unit, whether the range is one-sided or plus and minus, output (voltage or 4-20 mA), supply, accuracy grade, and pressure and electrical connections. Projects in the GCC often specify a display or a duct probe on the 267, so mention those too.
