ABSTRACT:
The invention makes it possible to detect and measure the movement of a moving member (50) through an amagnetic or low permeability metal wall. The installation requires ferromagnetic material targets placed at regular intervals over the moving member. The transducer is positioned facing the moving member by its detection face (16). It comprises two ferromagnetic cores (2, 8) surrounded both by an exciting coil (4) and a measuring coil (10), at whose terminals the measuring signal is taken. The latter is proportional to the variable reluctance of the magnetic circuit, which varies as a function of the position of the ferromagnetic targets (48). The transducer is completed by a balancing core (34). Application to the measurement of the displacement of control rods in the vessel of a pressurized water reactor.
