Abstract
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.
