This sensor is designed to measure absolute air pressure, especially the air box pressure of gasoline or Diesel engines plus temperature.
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 3 bar).

Installation Notes
The PST 1/PST 3 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. |
