Abstract
A process measurement system includes a sensor for producing a sensor signal as a function of a process parameter and a measurement circuit that converts the sensor signal to measurement data. A control circuit controls the amplitude of the sensor excitation to maximize signal strength over the entire operating ratio range of the sensor. This enhances resolution and noise rejection of the measurement circuit.
