Setra Systems, Inc. has added an integral static pressure probe for duct mounting to its Model 267 Series of low differential pressure transducers. Constructed of extruded aluminum, measuring 7.8" long and 1/4" in diameter, the probe is suitable for typical duct sizes. It is designed with a baffle at the tip, minimizing any velocity pressure errors. Additionally, the probe is designed with a gasket to seal against the duct, preventing leakage and providing accurate measurements. The probe allows for reliable maintenance-free installations and is available with Setra's Model 267 or Model 267 with optional LCD display. The Model 267 Series improved capacitance-sensor design allows up to 10 psi overpressure (in either direction), with no damage to the unit. Setra Systems, Inc.
