摘要： In a displacement detection device, an acceleration sensor generates at least a first acceleration signal relating to an axis of detection, and a displacement detection circuit is connected to the acceleration sensor has a comparator stage for comparing the acceleration signal with a programmable acceleration threshold and generates a displacement-detection signal. A high-pass filter is arranged between the acceleration sensor and the comparator stage so as to reduce a DC component of the acceleration signal. The cut-off frequency of the high-pass filter is modified according to the type of displacements that are to be detected.

摘要： A detection device for internal combustion engines exhaust gases post-treatment systems has a casing (2, 3) housing a circuit arrangement (21, 31) including humidity sensor means (32), for measuring the humidity of the gas. The circuit arrangement further comprises temperature sensor means (33) and pressure sensor means (22), for detecting a gas temperature value and a gas pressure value, respectively. The gas temperature value can be used for compensating the humidity value obtained through the humidity sensor means (32) and the pressure value can be used for deducing the clogging degree of a filter of the post-treatment system. Preferably the pressure sensor means (22) are housed in a first chamber (8) of the casing (2-3) while the humidity sensor means (32) and the temperature sensor means (33) are housed in a second chamber (10b) of the casing (2, 3).
