264
Model 264 Low Differential Pressure Transducer
Industry-standard Setra low differential pressure transducer for HVAC, cleanroom and room pressurisation, with ranges from 0.1 to 100 inWC, 4-20 mA or 0-5 V output and ±1% FS accuracy.
Description
The Setra Model 264 is one of the most widely specified low differential pressure transducers in building services. It measures duct static, filter differential and room pressurisation for VAV and fan control, critical environments, laboratories and fume hoods.
It is available in unidirectional ranges from 0 to 0.1 up to 0 to 100 inWC and bidirectional ranges from ±0.05 to ±50 inWC, with 4-20 mA (2-wire) or 0-5 V DC (3-wire) output. Standard accuracy is ±1% FS, with ±0.4% and ±0.25% FS options. The fire-retardant UL 94 V-0 enclosure snaps onto a 2.75-inch track, and the transducer carries a three-year warranty.
Trinity Solutions supplies and installs Setra pressure transducers and integrates them with BMS and room pressure monitoring systems.
