Aluminum hexport: 2x lighter in weight, 4x improved corrosion protection

Generation II or III conditioning electronics: accuracy ±1% Vcc; temperature compensation

Ratiometric output: ease of system integration; eliminates error in supply voltage fluctuations

Designed for under–hood environments: operating temperature range of -40°C to 135°C; fluid compatibility

Superior pressure sensing is required for highly efficient A/C loop systems that enable reduced fuel consumption and improved emissions. Sensata’s APsquared sensor (the AP stands for Automotive Pressure) is the low–cost, lightweight solution for accurate and robust pressure sensing in under–hood applications such as engine load management and compressor protection. With an aluminum port fitting and automotive grade connector, its corrosion protection is second to none. A patented square sense element and conditioning electronics provide field–proven EMC tolerance and reliability, as well as above average performance in high noise environments.

For those looking to optimize A/C system control, the APsquared sensor design ensures high quality, world class performance.

Optimized A/C performance:
– High pressure compressor protection
– Multiple stage fan control
– Low temperature compressor operation

Engine load management:
– Improved control around idle boost
– Reduced fuel consumption to meet C.A.F.E. standards
– Reduced emissions
