MAN Nutzfahrzeuge Aktiengesellschaft — Turbo pressure sensor

Component description Turbo pressure sensor +5V 2 1 Output 3 5 4 Plug connection Function The pressure sensor element consists of an Si diaphragm which contains several piezo- resistive (pressure-sensitive) semiconductor resistors. The pressure to be measured “de- flects” the sprung diaphragms. As a result, extended or compressed zones are created on the surface of the diaphragms. The action of these forces changes the electrical rat- ings of semiconductor resistor arrays arranged in these zones. These values are a measure for the pressure to be measured.
