ABSTRACT:
A pair of main coils are arranged with their axes horizontally located, for example between the wheels, and symmetrically with respect to a longitudinal vertical plane of symmetry of the vehicle; a pair of auxiliary coils are located adjacent the horizontal coils, symmetrical with respect to said plane and having axes located at least approximately in a common vertical plane transverse to the longitudinal plane of symmetry of the vehicle, the coils including with said longitudinal plane an acute angle to open outwardly in the downward direction towards the conductor, preferably in the range of between 10.degree. to 45.degree., for example about 20.degree.. The main coils are differentially connected, the auxiliary coils are additively connected, and the output signals are divided to form a proportional ratio which forms the error signal indicative of deviation of said longitudinal plane of symmetry, at the location of the coils, from the conductor.
