WHITE PAPER PAGE 3 TE PRESSURE SENSORS /// WHITE PAPER The Importance of Pressure Sensors in HVACR Systems TOUGH ENVIRONMENTS REQUIRE RUGGED, ROBUST, RELIABLE SENSORS While a range of board mount pressure sensors are used in HVAC systems for filter monitoring as well as pressure monitoring throughout a forced air system, the bulk of the pressure sensing is accomplished using heavy duty pressure sensors to monitor refrigerant pressure in compressor-based systems as well as water or other liquid pressures in large commercial chillers and other refrigeration systems. The environment found in commercial and residential HVACR systems can be one of the most challenging industrial environments. With large temperature swings, high moisture levels and, often, electrical noise, the HVACR system requires sensors that are rugged enough to function continuously while providing accurate and repeatable readings. MICROFUSED TM TECHNOLOGY TE offers the M3200, the latest in a long line of pressure sensors designed and manufactured using our Microfused TM technology. Derived from demanding aerospace applications, our technology employs micro- machined, silicon piezoresistive strain gages fused with high temperature glass to a stainless-steel diaphragm. Our technology is a unique construction of the sensor front end made from a single piece of steel. The result is a hermetic fitting that is free from failure-prone welds and o-rings. Bottom line – it's more reliable. The M3200 is an industrial pressure transmitter that reaches a new price performance standard for demanding HVACR pressure applications. Available with a wide range of threaded pressure port and connector options, it has standard pressure ranges available from 100 to 5000psi or 7 to 350bar. The M3200 is designed for ease of installation and reliable performance in harsh environments. What follows is a technical description of our technology and key benefits for an HVAC application. At TE, we believe these are important features for design engineers to consider when creating next-generation HVACR systems.
