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 to 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.

Installation Notes
The sensor can be connected directly to most control units. |
For temperature measurement please use a pull-up resistor with an optimal value of 4.6 kOhm. |
The sensor has a protection for overvoltage, reverse polarity and short-circuit. |
Please find further application hints in the offer drawing and free download of the sensor configuration file (*.sdf) for the Bosch Data Logging System at our homepage. |
Safety Note
The sensor is not intended to be used for safety related applications without appropriate measures for signal validation in the application system. |
