This sensor is designed to measure relative gasoline pressure and gasoline temperature in port injection systems.
The pressure measurement of the sensor is by means of a piezoresistive element which is acted on by a silicon diaphragm in contact with the fluid being measured. The reference (relative) pressure is provided via an opening in the sensor housing and acts on the active upper side of the silicon diaphragm.

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. |
