With millions of sensors installed world wide, Setra’s 264 is the “standard” for low differential pressure measurement in HVAC building automation. The 264 very low differential pressure transducer uses a dead-ended stainless steel welded capacitive sensing element that requires minimal amplification and delivers excellent accuracy and longterm stability in critical installations. The 264 has a 3 year, unconditional warranty, giving the end-user peace of mind well beyond the initial commissioning phase and guarantees performance well after the BAS warranty. The 264 utilizes a robust design that offers brass barbed fittings, and an optional conduit cover for easy and consistent installation. The industry standard The 264 has been a consistent and trusted HVAC sensor for over two decades. The reputation of reliability and quality with exceptional delivery time has helped the 264 remain the trusted choice for any low differential pressure applications. Low Differential Pressure Transducer Features • Industry standard for very low differential pressure Convenient installation The 264 is available in both a wall and conduit versions providing the installer with flexible mounting options. The base mount allows the sensor to be installed anywhere, allowing for a simple installation. • 3 year unconditional warranty The core technology of the 264 is the all stainless steel capacitive sensing • Up to 10 PSI overpressure (range dependent) element. Setra designs and manufactures all of their sensing elements • Installation time minimized w/ mounting options resulting in full control over the process and quality of every single sensor. • Reverse wiring protection The welded dead-ended capacitive sensors requires minimal amplification • Internal regulation permits use with unregulated DC and delivers excellent accuracy and longterm stability. Setra’s technology power supplies • Fire retardant case (UL 94 V-0 approved) has been used in over 8 million installations and has the highest field acceptance rate in the industry. Applications • HVAC/R systems • Room pressurization for critical environments • Energy management systems • Variable air volume and fan control (VAV) • Environmental pollution control • Lab & fume hood control © Setra Systems, Inc.
