The TMAP sensor provides 2 outputs
Intake manifold absolute pressure output /Derived from a MEMs based sensing element
Intake manifold air temperature output / Provided by a NTC thermistor Together with information of cylinder volume, we can calculate the air mass
Performance and customer interface compatible with Bosch TMAP
Single chip solution ,SMT for EMA fabrication process
NTC thermistor for temperature measurement, resistance welding used for assembly
Steel ball for vent hole sealing, laser marking for better traceability
Different pressure ranges are available on customer request.
With information of fuel pressure sensor, ECU can calculate the ratio of air & fuel, increase or reduce fuel injecting time to get the optimal ratio of air & fuel.
According to the change of vacuum in intake manifold, the pressure part of intake temperature and pressure 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.
Customized to customer choice of connection system.
Custom packaging can be provided to meet any need, please contact KESENS Engineering for details.
