Product Application
This product integrates an NTC temperature sensor and MAP absolute pressure sensor with EMC protection. It withstands extreme temperatures, vibration, thermal shock and chemical contamination, making it ideal for harsh automotive environments. It simultaneously detects changes in gas temperature and absolute pressure within the intake manifold, providing baseline signals to the ECU (Engine Control Unit) for fuel duration calculation.
Engine Control
Provides intake pressure/temperature data for air-fuel ratio calculation
Turbocharging
Monitors boost pressure to optimize turbo response
EGR System
Precisely controls EGR valve opening to reduce emissions
Product Composition & Working Principle
The MEMS pressure sensor PCBA module consists of a pressure sensor chip, signal conditioning circuit and connection interface, suitable for automotive engine systems, transmission systems and exhaust treatment systems. Its primary function is to convert detected pressure signals into electrical signals for transmission to processing systems.
- MEMS pressure chip detects intake manifold absolute pressure
- NTC temperature sensor detects intake air temperature
- Dedicated ASIC chip performs signal conditioning and compensation
- Outputs standard signals to ECU for fuel injection control
