The Setra Model 264 is the global industry standard very low differential pressure transducer engineered for exceptional accuracy, long-term stability, and peace-of-mind reliability in critical HVAC building automation and energy management systems. At the engineering core of this compact instrument is an all-stainless steel, dead-ended welded capacitive sensing element that requires minimal amplification and prevents fluid cross-contamination. Optimized for clean, non-conducting gas media, the Model 264 features a robust structural layout that accommodates standard wall or conduit mounting styles with integrated brass barbed fittings for rapid field installation. Operating on a low-cost, unregulated 9 to 30 VDC power supply, it delivers a highly stable 4-20mA current loop or analog voltage output, providing clean telemetry density for advanced Building Automation Systems (BAS). Backed by an industry-leading 3-year unconditional warranty, the Model 264 eliminates ground loop issues and maintains superior tracking for static pressure, cleanroom, and VAV box control architectures.
