Bosch Motorsport map sensor 3.5 bar with NTC

Applications
This sensor is used to measure the absolute intake-manifold pressure. On the version with integral temperature sensor, the temperature of the drawn-in air flow is also measured.
Design and function
The piezoresistive pressure-sensor element and suitable electronic circuitry for signalamplification and temperature compensation are mounted on a silicon chip. The measured pressure is applied from above to the diaphragm’s active surface. A reference vacuum is enclosed
between the rear side and the glass base. Thanks to a special coating, both pressure sensor and temperature sensor are insensitive to the gases and liquids which
are present in the intake manifold.
