摘要 <p>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).</p>
