Wireless monitoring and profiling of reactor conditions using an array of sensor-enabled RFID tags placed at a known reactor height

摘要

A system and method are disclosed for wirelessly monitoring process conditions in a reactor vessel. An array of sensor-enabled radio frequency identification (RFID) tags are placed at known heights within the catalyst bed of the vessel and used to measure various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and wirelessly connected to multiple transceivers. The use of multiple transceivers identifies the location of each of the sensor-enabled RFID tags in a three-dimensional space, and conveys information indicating the detected condition in the reactor for a query of each sensor-enabled RFID tag. It enables the application of triangulation methods to receive response signals.
