Abstract
An automatic transducer selection system for fluid pressure measurement functions by using two or more transducers with different ranges of accuracy and also by incorporating comparator circuitry which automatically selects the transducer reading nearer to full scale. An electronic signal or output from the comparator is preferably nested such that a continuous voltage is generated in accordance with the fluid pressure being measured, thus making the system appear to function as a single transducer with a wide range of accuracy.
