APPARATUS FOR MEASURING THE POSITION OF A PISTON IN A CYLINDER, ASSEMBLY COMPRISING A CYLINDER, PISTON AND SAID APPARATUS AND AIRCRAFT ENGINE COMPRISING SUCH AN ASSEMBLY

The device has two position sensors e.g. linear variable differential transformer (LVDT) type sensor, respectively comprising ferromagnetic cores (20, 40) cooperating with transformers (10, 30). The cores are integrated to a maintaining finger (31), and transformers are integrated to a cylinder (1)....

Beschreibung
Zusammenfassung:	The device has two position sensors e.g. linear variable differential transformer (LVDT) type sensor, respectively comprising ferromagnetic cores (20, 40) cooperating with transformers (10, 30). The cores are integrated to a maintaining finger (31), and transformers are integrated to a cylinder (1). The cores and the transformers are moved in translation along an axis parallel to an axis of the cylinder. The cores are integrated to same finger, where the finger is connected to a piston (2) by a ball joint (50).
