Temperature Absolute Pressure Sensor

The TMAP is composed of pressure sensor and temperature sensor, 2 sensors into 1 product.

Feature and benefits

The TMAP sensor provides 2 outputs, intake air pressure and temperature. 

Intake manifold absolute pressure output derived from a MEMS based sensing element.

Intake manifold air temperature output from a NTC thermistor.

Performance and customer interface compatible with major tier 1 suppliers’ TMAP.

Single chip solution ,SMT for EMA fabrication process.

Steel ball for vent hole sealing, laser marking for better traceability.

Different pressure ranges are available on customer request.

Product Application

With information of intake air pressure and temperature sensor, ECU can calculate the intake air mass flow and air/fuel ratio, increase or reduce fuel injecting time to get the optimal ratio of air & fuel.

Operate
Basic Principle

According to the change of vacuum in intake manifold, the pressure part of TMAP sensor converts into voltage signal from the change of internal resistance of sensor, which is used for ECU computer to correct fuel injection quantity and ignition timing angle. The temperature part consists of a negative temperature coefficient thermistor. When the temperature is high, the resistance decreases; when the temperature is low, the resistance increases. With the change of temperature resistance, the voltage changes, and the signal changes from 0V to 5V.
