Abstract: Disclosed is a system and method for wirelessly monitoring process conditions within a reactor vessel. An array of sensor-enabled radio frequency identification (RFID) tags is placed at known heights within a catalyst bed of a vessel and are used to measure 10 various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to multiple transceivers. The use of multiple transceivers allows for the application of triangulation methods to identify the location of each of the sensor-enabled RFID tags in three-dimensional space and for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of the sensed condition within the reactor.

Abstract: Disclosed is a system and method for wirelessly monitoring 5 process conditions within a reactor vessel. A plurality of sensor-enabled radio frequency identification (RFID) tags are disposed at known locations throughout a catalyst bed of a vessel and are used to measure various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to a transceiver. A transceiver 10 provides for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of both the three-dimensional location of the sensor-enabled RFID tags and the sensed conditions within the reactor. This allows for three-dimensional profiling of the specifically measured condition within the reactor.
