Abstract

The encapsulation comprises a dielectric circuit plate 10a having an aperture which receives a projection 14 on a lower pole piece 12. The Hall plate 15, which is of semiconductor material with a doped sensitive region, is mounted on the projection 14 and its electrodes are connected to conductive tracks 19 on the circuit plate. An upper pole piece 11 is mounted on the circuit plate via a spacer 10b and has a projection 13 which overlies the Hall plate and defines a small active air gap. The assembly may be placed in an air gap in a magnetic circuit carrying a coil the current flowing in which can thereby be measured. The circuit plate can be extended and may carry other circuit elements connected to the Hall plate by conductive tracks (Figure 5). <IMAGE>
