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.
