Pressure Sensor Air PS-AA

This sensor is designed to measure absolute air pressure, especially the air box pressure of gasoline or Diesel engines.

An integrated circuit combines a piezo-resistive sensor element and electronic systems for signal-amplification and temperature-compensation. The output of the sensor is an analog, ratio metric signal.

Two different pressure ranges are available (0.1 to 1.15 bar or 0.2 to 2.5 bar).



  • Application: 0.1 to 1.15 bar or 0.2 to 2.5 bar
  • Response time: 1 ms
  • Pressure reference type: Absolute
  • Power supply: 5 V
  • Weight: 20 g

Installation Notes

The PS-AA is designed for engines using ROZ95, ROZ98, M15, E22 and Diesel.

The sensor can be connected directly to most control units.

To avoid noise, an ECU-input circuit with a RC-low pass filter (tau = 2 ms) is recommended.

Use engine oil (5W40) as O-Ring grease (no silicone based grease).

Avoid miss-pinning (max. 5 minutes at I = 0.3 A).

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.

To avoid damage caused by condensate the maximum mounting position from vertical is +-60°.

Safety Note

The sensor is not intended to be used for safety related applications without appropriate measures for signal validation in the application system.
