INDUSTRIAL PROCESS CONTROL TRANSMITTER WITH MULTIPLE SENSORS
摘要
<p>An industrial process control transmitter (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) is configured to provide an output related to a sensed process variable. A multiplexer (66) is configured to selectively couple the first and second inputs to the measurement circuitry (68). An equalizer circuit (100) is coupled to the output of the multiplexer (66) and configured to bring the selectively coupled First or second input and the measureement circuit to a common voltage potential</p>
