ABSTRACT:
A device is disclosed for sensing the contents of a fluid flowing in a duct system, such as in a ventilation duct. In at least one embodiment of the invention, the device includes a sensing element and a tubular body extending over a cross-sectional portion of the duct at issue and a supply duct with an inlet facing the main flow direction of the fluid and a discharge duct with an outlet located downstream of the inlet, to divert from the flowing fluid a partial flow which is made to pass the sensing element and then re-enter the duct. The outlet is located upstream of the downstream boundary of the tubular body.
