Temperature Absolute Pressure Sensor
Product Description
The TMAP is composed of pressure sensor and temperature sensor.
Feature and benefits
u The TMAP sensor provides 2 outputs
u Intake manifold absolute pressure output /Derived from a MEMs based sensing element
u Intake manifold air temperature output / Provided by a NTC thermistor Together with information of cylinder volume, we can calculate the air mass.
u Performance and customer interface compatible with Bosch TMAP
u Single chip solution ，SMT for EMA fabrication process
u NTC thermistor for temperature measurement, resistance welding used for assembly
u Steel ball for vent hole sealing, laser marking for better traceability
u Different pressure ranges are available on customer request
