ABSTRACT:
A temperature transmitter and a process control system includes a sensor input for coupling to a temperature sensor having a temperature dependent resistance. The resistance measuring circuitry couples to the sensor input and provides a resistance output related to resistance of the temperature dependent resistance. Analog to digital conversion circuitry couples to the sensor input and provides a digital output related to AC signals across the sensor input. Digital signal processing circuitry isolates a Johnson noise component of the AC signals and provides a digitized Johnson noise output. Temperature measurement circuitry provides a calibrated temperature output based upon the resistance output and the digitized Johnson noise output. Output circuitry transmits the calibrated temperature output over the process control loop.
