Embodiment Construction

[0020] Figure 1A with 1B is a diagram illustrating a process measurement or control system known in the art.

[0021] Figure 1A is a diagram illustrating a process measurement or control system 10 including: sensor assembly / process transmitter 12 , control system 16 , transmission line 14 and process piping 18 . A sensor assembly / process transmitter may measure any of a number of process characteristics. In this embodiment, sensor assembly / process transmitter 12 measures temperature. Control system 16 may use the measured temperature information for various purposes, including making a record of the measurements, providing control instructions to control elements based on the information, or reporting the measurements to another measurement or control system. The transmission line 14 may be a multi-wire cable, a fiber optic cable, or a wireless connection. Process piping 18 may also be any of a variety of process conduits, including process intermediate storage tanks, sto...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 61 / 107,533, entitled "Sensor / Transmitter "Plug-and-PLay" For Process Instrumentation," filed October 22, 2008, the entire disclosure of which is incorporated herein by reference . technical field [0003] The present invention relates to industrial process transmitters and sensors. In particular, the invention relates to configuring a process transmitter with information specific to an attached sensor assembly. Background technique [0004] Industrial process transmitters and sensors are used to sense various properties of fluids flowing through pipes or contained within conduits and to send information related to those process properties to control, monitoring and / or safety systems located remotely from the process measurements . Sensor assemblies generally include sensors, sensor wires, isolation materials, and mounting equipment. The sensor ass...
