Disclosed is a sensor for spectrometric analysis of a variable-pressure gaseous fuel for automotive vehicle intended to be mounted in the flow circuit for the fuel linking the fuel tank to the engine of the vehicle. The sensor includes a circulation pipe for the variable-pressure gaseous fuel, a sliding guidance tube for an optical flux and a unit for displacement of the sliding guidance tube, on the basis of the variable-pressure gaseous fuel tapped off from the circulation pipe, so as to adapt the distance separating the first window from the second window as a function of the variation in pressure of the variable-pressure gaseous fuel circulating in the circulation pipe.

Sensor for spectrometric analysis of a variable-pressure gaseous fuel for automotive vehicle

The object is to ensure the absence of friction between a housing supporting a sensor and a mounting arranged to support a target, and the absence of load take-up resulting from the contact and lack of precision among mounting interfaces. This involves forming, in a mounting position, a clearance between the mounting and the housing and then releasing the target mounting in the operative position of the sensor. A cylindrical recess for freely receiving with a clearance the mounting supporting the reference element serving as a target and which is mountable on the shaft, is provided in the housing which supports the sensor and which is attachable to the stationary part. Removable locking elements provided between the mounting and the housing maintain the latter in an initial position when the locking elements are operative and, when inoperative, release the mounting mounted on the rotary shaft from the housing.
