Abstract
In order to ensure a reliable body earth and insulate a capacitance type position sensor from external noise, an electrically conductive tube is insulatingly mounted within an electrically conductive housing. The capacitance developed between the tube and a piston rod which is reciprocally arranged therein is measured while the rod and the conductive body are electrically connected. By soundly grounding the rod a secure ground for the housing is established.
