Abstract
La présente invention concerne un capteur de position qui peut être utilisé dans des environnements de forage haute pression, notamment dans des applications de mesure de fond en cours de forage. Ledit capteur comprend un premier élément auquel est couplée solidement au moins une broche facilement magnétisable, et un second élément auquel sont couplées solidement une ou plusieurs bobines. Les bobines comportent des fentes à travers lesquelles les broches peuvent se déplacer lorsque les éléments tournent les uns par rapport aux autres. Un montage de circuits détecte un changement de linductance dans les bobines lorsque les broches entrent dans les fentes ou en sortent. En conséquence, la position du premier élément par rapport au second peut être déterminée. Le capteur de position comprend deux parties principales : un agencement broche/bobine qui peut supporter une pression élevée et ne subit pas dusure, et un montage de circuits électroniques classique qui est protégé de la pression derrière une cloison.
