Abstract: A sensor assembly with a sensing element sends a sensor signal from the sensing element to attached process transmitter over sensor connection wires. The sensor assembly has memory circuitry for storing information related to the sensor assembly and interface circuitry that provides for digital communication of the stored information with the attached process transmitter. This digital communication is sent over the sensor connection wires.

Abstract: A temperature transmitter assembly includes a thermocouple and a temperature transmitter. The thermocouple has a first conductor and a second conductor connected to each other at a junction. The temperature transmitter has diagnostics that determines a resistance of the thermocouple and based on the determined resistance, provides an indication of whether the first conductor and the second conductor are shorted together before the junction.
