.:Sensata Technologies offers new high-pressure sensor for CO2-driven (R744) HVAC/R system needs :.

January 23rd, 2008

Pressure sensors and switches meet high-pressure demands of growing R744 HVAC/R applications.

STracking the growing environmental and regulatory demands for R744 based air-conditioning and refregeration systems, Sensata Technologies has developed a line of pressure sensors and switches designed to withstand the R744's high-pressure operating range. These new devices support this ozone-preserving, non-toxic and non-flammable refrigerant and are among the sensing and power-protection products on display at the air-conditioning, heating, refrigeration expo in NYC.

Designing to the technical requirements of R744 systems, Sensata's engineering team combined proven, robust low-cost sensor and switch technologies with HVAC/R system needs to deliver R744-capable products to the HVAC/R industry.

"The industry is deploying more and more R744 systems because they offer excellent efficiency and have zero global warming potential," said John Forsyth, Sensata Technologies HVAC Marketing Manager. "But with those benefits the sensors and switches need to perform accurately at roughly five times the pressures of conventional AC or refrigeration systems."

Sensata's R744 pressure switch uses a proven Klixon™, snap action disc design to meet R744 system's high pressure demands. The pressure switch is capable to 2,000 psi and across the wide temperature range of -20° to 120°C.

The R744 pressure switch uses strain gages that are glass-fused onto a stainless steel membrane. This inherent hermetic structure leads to unparalleled media resistance and creates a very robust package design. This transducer is capable to 30,000 psi and accurate (within 1%) across a temperature range of -40° to 135°C. The transducer's high resistance to vibration and electromagnetic resistance makes this device the preferred choice for R744 applications.

Sensata Technologies pressure sensors and switches come in a wide range of fittings, packaging materials, pressure ratings and electrical inputs/outputs. The company will be at the AHR Expo in NYC in January.
