Sensors

The Delphi Manifold Absolute Pressure/Manifold Air Temperature (MAP/MAT) Sensors provide precise measurements of manifold absolute pressure, manifold air temperature, and other high output gasoline and diesel engine performance characteristics, in operating pressure ranges from 20 kPa to 102 kPa, and 10 kPa to 350 kPa (0.2 bar to 1.0 bar, and 0.1 bar to 3.5 bar).

Delphi Manifold Absolute Pressure/Manifold Air Temperature Sensors are designed to perform in harsh environments such as extreme temperatures and vibration, thermal and mechanical shock, and chemical contamination. They provide two separate outputs critical to air/fuel ration optimization:

• One voltage output proportional to engine intake manifold pressure
• Thermistor output proportional to manifold air temperature

Benefits

• Two-in-one design yields cost and space savings, with one less component, wire and connector
• Electronic compensation for precise measurements in a variety of environments
• Reliable and robust:
• Low part count
• Automotive grade
• ISO/TS 16949 certified
• Mounting flexibility
• Designed for under-hood environments
• Appropriate for a wide range of automotive and non-automotive applications

Features

• All-silicon, solid-state microelectronic technology
• Temperature compensation
• Electromagnetic interference (EMI) protection
• Air temperature output
• Electronically programmable trim to customer specifications
• MAP sensor precision with reliable thermistor output

Typical Applications

Delphi Manifold Absolute Pressure/Manifold Air Temperature Sensors can be used for manifold absolute pressure, barometric pressure, and exhaust gas recirculation (EGR) pressure applications in gasoline and diesel engine programs.

Delphi MAP/MAT Sensors can be used in other non-automotive gaseous pressure applications within appropriate ranges.
