  • Capacitor-coupled ohmic resistance position sensor
    Patent number: 5347875
    Abstract: A position sensor comprises a pair of elongated members of strip or tape shape having a high specific ohmic resistance, and a target member capacitively coupling two electric signals respectively flowing through the pair of elongated members, which target member is disposed in a relationship allowing sliding movements following the pair of elongated members, wherein the position of the target member relative to a reference section of the pair of elongated members is determined as a function of a phase angle difference between an alternating electrical signal supplied to one extremity of one of the pair of elongated members and another alternating electrical signal associated with the supplied electrical signal and taken off from one extremity of the other of the pair of elongated members.
