The Setra Model 264 is a low differential pressure transducer designed for HVAC building automation. It uses a dead-ended stainless steel welded capacitive sensing element, requiring minimal amplification and delivering excellent accuracy and long-term stability in critical installations. The product offers a 3-year unconditional warranty and features robust design with brass barbed fittings and an optional conduit cover. It is available in wall and conduit versions for flexible mounting. The Model 264 has been a trusted choice in the HVAC industry for over two decades due to its reliability and quality. Applications include HVAC/R systems, room pressurization for critical environments, energy management systems, variable air volume and fan control (VAV), environmental pollution control, and lab & fume hood control
