摘要

Transmitter for control of industrial process, and method and apparatus for measuring values of the sensor from first and second sensors in a transmitter for control of industrial process. A transmitter for control of industrial process (16) includes a first input configured to couple to a first sensor, and a second input configured to couple to a second sensor.Measurement circuitry (68) are configured to provide an output related to a process variable sensoriada. A multiplexer (66) is configured to selectively couple the first and second inputs to the measurement circuit (68).An equalizer circuit (100) is coupled to the output of the multiplexer (66) and configured to be coupled to selectively bring the first or the second input and the circuit of measurement for a common voltage potential.
