Abstract: A sensor head, capable of sampling and maximizing a stream of gas before transmitting the stream of gas to a sensitive element of a sensor, includes a guide and a capsule. The guide is substantially cylindrical according to a first axis, hollow and closed with an exception of a flow inlet comprising two openings facing each other, pierced in the guide along a second axis substantially perpendicular and coplanar to the first axis, and a flow outlet comprising a hole drilled in the guide along the first axis. The capsule is substantially cylindrical along a third axis substantially parallel to the first axis, including the guide, hollow and closed with an exception of a mouth pierced in the generating surface of the capsule according to a fourth axis substantially perpendicular to the first axis and to the second axis and substantially perpendicular and coplanar to the third axis. A sensor, preferably of the photoacoustic type, includes such a head.
