Abstract
Improvements in deviation measurement devices, formed by a chain of elements articulated around axes parallel to a given direction perpendicular to the theoretical direction of a bore, characterized in that each element i, in which i is the order number of the element counted from the element 1 located more deeply, comprises a variable resistance ri commanded by the angle ai between two elements and equal to the kia value ri where k is a constant common to all the variable resistances of the various elements 1 to n that constitute the whole of the chain, and where ri is a constant of the element of order i.
