The present invention is a device that allows the pressure inside an aircraft landing gear shock strut to be measured. A charging valve is modified by integrating a small pressure sensing device into the stem of the part such that the active diaphragm is subjected to the pressure within the charged vessel. The wires from the pressure sensing device are connected to a receptacle or connector in the bore of the stem such that a corresponding electrical receptacle may be mated for the purposes of making a measurement. The internal receptacle is designed such that the flow of air or oil is not excessively impeded and normal servicing tools do not interfere with the receptacle.

La présente invention concerne un dispositif qui permet de mesurer la pression dans la jambe élastique du train d'atterrissage d'un avion. Un clapet de remplissage est modifié par l'intégration d'un petit dispositif de détection de pression dans la tige de la pièce de telle sorte que la membrane active est soumise à la pression à l'intérieur du récipient rempli. Les fils électriques à partir du dispositif de détection de pression sont connectés à un réceptacle ou à un connecteur dans l'alésage de la tige de telle sorte qu'un réceptacle électrique correspondant peut être connecté à des fins de réalisation d'une mesure. Le réceptacle interne est agencé de telle sorte que l'écoulement d'air ou d'huile n'est pas excessivement gêné et que des outils d'entretien normaux ne gênent pas le réceptacle.
