[en] A new rotation sensor is developed and tested for the next generation of Ariane space launchers. It aimed at measuring accurately the angular position of an admission valve (target sensitivity of 0.01°) from cryogenic (4K) to room temperature without recalibration. The measurement has to be done contactless and through pipe walls. Innovative electromagnetic application, cryogenic design and data treatment allows reaching the specifications.
