Abstract: A movement measuring sensor comprises a rule having parallel surfaces and a slider having parallel surfaces opposite the first parallel surfaces and movable relatively to the rule in a direction parallel to the surfaces. Each surface of the slider is provided with a first set of n electrically interconnected conductive strips disposed at a pitch p in such direction and the rule has N electrically interconnected conductive strips disposed at the same pitch p and located opposite each of the first sets. The two capacitances each formed by a set of n strips and a set of N strips are in series relation.
