Abstract
An air core gauge having orthogonally related coils that react with a rotor magnet to angularly position an indicating pointer, suitable for use as either a pressure,temperature, or fuel gauge. All-attitude pointer zero return is achieved with a stationary magnet, and voltage regulation is eliminated with a zener diode in series with one of the coils.
