Abstract
A converter is provided for transforming the parallel output of a remotely located gas turbine engine parameter sensor into serial form for transmission to an engine control unit. The converter is comprised of an interrogator which operates to sequentially interrogate a plurality of encoder magnetic cores which contain the sensed digital information. The interrogator is comprised of a plurality of magnetic elements, each of which is connected to a corresponding individual encoder magnetic core. The magnetic elements are normally maintained in a saturated state by two electrical current signals which are applied through appropriate biasing circuitry. The current signals and biasing circuitry also act to sequentially unsaturate individual magnetic elements. A high frequency excitation current is also applied to each of the magnetic elements. As each magnetic element unsaturates, an interrogation current generated by the excitation current is transmitted to a corresponding encoder magnetic core. A single output conductor is connected with all of the magnetic cores for transmitting the serial information to the control unit.
