Embodiment Construction

[0012] As described in US Patent Application Publication No. 2010 / 0302008 "SENSOR / TRANSMITTER PLUG-AND-PLAY FOR PROCESS INTSTRUMENTATION" incorporated herein by reference The plug-and-play process transmitter enables automatic loading of configuration data for sensor components into the process transmitter without the use of additional wiring, bringing true plug-and-play functionality to the realm of process instrumentation. The present invention is used for reading and writing the characteristic information of sensor peripheral element, and need not use extra wiring, plug and play type functionality is extended to sensor peripheral element.Physically connect plug and play type sensor assembly to sensor peripheral element, Allows a plug-and-play process transmitter connected to a sensor assembly to access memory locations on RF communication and data storage circuitry (e.g., an RFID chip) within a sensor peripheral that uses only analog sensor signals sensor wires.

Abstract

A plug-and-play sensor peripheral component includes an electrically conductive physical connector; an electrical connector; a transformer; and an RF communication and data storage circuit. The electrical connector is electrically connected to the physical connector by a first conductive path. The transformer is electrically connected to the RF communication and data storage circuit. The transformer and the RF communication and data storage circuit are electrically isolated from the physical connector and the electrical connector. Electrically connecting the physical connector to the electrical connector by other than the first conductive path inductively couples the RF communication and data storage circuit to the first conductive path.

Description

technical field [0001] The present invention relates to industrial process transmitters and sensors. More specifically, the present invention relates to the construction of process transmitters with information specific to connected sensor peripheral components. Background technique [0002] Industrial process transmitters and sensors are used to sense various characteristics of fluids flowing through pipes or contained within vessels, and to transmit information related to these process characteristics to control, monitoring and / or security system. Sensor assemblies generally include sensors, sensor wires, isolation material, and mounting accessories. Sensor assemblies detect process parameters such as pressure, temperature, pH or flow. A process transmitter electrically connected to the sensor assembly by sensor wires receives a sensor output signal from the sensor assembly. The transmitter reads the sensor output signal received from the sensor assembly and converts i...
