Abstract
A fluxgate compass direction sensor in which a fluxgate is mounted relative to a receptacle by means of a flexible circuit. The fluxgate is also suspended in a liquid by means of a float. In use, if the receptacle tilts relative to the horizontal, the level of the liquid will move to retain a horizontal aspect and the float, being buoyant in the liquid, will retain the fluxgate in the horizontal plane. The flexible circuit acts to allow tilting of the float and fluxgate relative to the receptacle while retaining the fluxgate in lateral and directional alignment relative to the receptacle.
