Tracking the growing
environmental and regulatory demands for R744-based air-conditioning and
refrigeration 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 recently displayed at the AHR Expo (New
York, USA).
 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. Sensata’s R744 pressure
switch uses a proven Klixon, snap-action disc design to meet R744 systems’
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 sensor 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.
According to the company’s press release, the transducer’s high resistance to
vibration and electromagnetic resistance make this device the preferred choice
for R744 applications. |
