Abstract
The invention is a system for combining the outputs of two transducers to provide a continuous reading over the combined ranges of the two transducers. The system applies an A.C. signal to the appropriate transducer; the steering for the excitation is controlled by the system microprocessor. The transducers are connected in series mechanically such that the low-range transducer is mechanically stopped before it is overloaded. The outputs of the transducers are connected in parallel and applied to the pre-amp which amplifies the A.C. error signal. The signal from the pre-amp is then applied to the analog-to-digital converter (ADC) for conversion. The ADC converts the pre-amp signal which is then sent to the system microprocessor over a serial link. The system microprocessor then applies the appropriate weighing algorithms to the data and then conveys that information to the parent system.
