• Relative fluid pressure and temperature measurements
• Pressure measurement range 0 to 280/350 bar
• Temperature measurement range -40 to 140°C
This sensor is designed to measure absolute gasoline pressure and gasoline temperature in direct injection systems.
The pressure measurement is based on the expansion of a steel diaphragm, where strain gauges are placed on a Wheatstone bridge. The measured signal is proportional to the pressure and is processed in an application specific integrated circuit.
The temperature measurement is conducted by an NTC thermistor. The main feature of this sensor is its compact design and the integration of two functions (temperature and pressure measurements) in a common housing.
