摘要
A temperature transmitter in a process control system includes a temperature sensor which senses temperature and provides a sensor output related to sensed temperature. An analog-to-digital converter coupled to the sensor output provides a digitized output related to the sensor output. A microprocessor receives the digitized output, compensates the digitized output and provides a temperature output. Comparison circuitry compares the sensor output to a first threshold and provides an inhibit signal to the microprocessor if the sensor is outside of the first threshold.
