Abstract
A micromachined measuring cell is adapted to be mounted on a support and has a measuring sensor (121) and an assembly structure (120) distinct from one another and associated with each other by a connecting arm (128). At least one part element (103b) of the assembly structure, one part (133) of the connecting arm and one part (103a) of the sensor (121) are produced as one single piece. The assembly structure (120) of this measuring cell is preferably in the shape of a frame surrounding the sensor (121).
