<p>The device is characterised in that it comprises: one ring-shaped sensor (1) body comprising a main part (3) delimiting a sensor chamber (5) extended by a threaded part (6) as well as a skirt (4) around the sensing chamber (5) and defining a support surface (8) to be fixed on the wall (10) of the can or bag to be checked, a tubular connecting screw (2) coupled with continuous analysing means and designed to co-operate with the sensor (1) body, and sensing means capable of cutting or perforating the wall (10) of the can or bag to be checked so as to allow the gases, if any emitted in this can or bag, to enter the internal conduit (11) of the connecting screw (2) to be sensed by the continuous analysing means.</p> |
