Abstract:
A temperature transmitter for sensing a temperature of an industrial process includes a temperature sensor arranged to provide a sensor output related to the temperature of the industrial process. Measurement circuitry is coupled to the temperature sensor and configured to determine the temperature of the industrial process based upon the sensor output. Output circuitry provides an output related to the measured temperature. A memory is configured to store temperature information related to excessive temperature events experienced by the temperature sensor. Diagnostic circuitry diagnoses a condition of the temperature sensor or other components based upon the stored temperature information.
