摘要

The evaluation system has a low-pass filter for receiving the pressure sensor signal representing the pressure of a fluid. The output signal of the pressure signal is used as an acceleration signal, or alternatively the pressure sensor signal is fed through a band-pass filter and the obtained output used as an acceleration filter. Pref., the pressure signal is checked for plausibility to verify the correct function of the pressure sensor (16). Pref. the latter is used to detect the pressure difference within the fuel tank vent line for an automobile. ADVANTAGE - Provides acceleration sensor with easy function testing.
