The PSS is specially designed to measure absolute pressure in gasoline direct injection applications. This sensor is also compatible with other kind of fluids e.g. Diesel, engine oil, transmission oil or brake fluid.
The sensor uses a thin layer technique to achieve high accuracy pressure measurements. The stainless steel measuring cells with piezoresistive bridges are hermetically welded with stainless steel pressure ports. The internal reference ensures ambient pressure independent measurements.
The main benefits of this sensor are its high accuracy, its wide measurement range and its robust and compact design.

Installation Notes
The PSS- can be connected directly to most control units. Please consider the TCI for the electrical connection of the sensor. |
The sensor has a protection for overvoltage, reverse polarity and short-circuit. |
Please do not fix the sensor directly to the engine block to avoid undesired strong vibrations. |
Each mounting orientation is possible. |
Please consider using the adapter F02U.002.711-01. |
The sensor meets all EMV, EMC and ESD automotive standards. |
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. |
