Disclosed is a system and method for wirelessly monitoring process conditions within a reactor vessel. A sensor-enabled radio frequency identification tag is located within a catalyst bed of a vessel and used to measure various conditions within the vessel. The sensor-enabled RFID tag is wirelessly linked to a reader for transmitting interrogation signals and for receiving transponder signals from the sensor-enabled RFID tag that carry information representative of the measured condition.

Wireless reactor monitoring system using passive sensor enabled RFID tag

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 unspecified or random 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 multiple 10 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.

Wireless monitoring and profiling of reactor conditions using plurality of sensor-enabled RFID tags and multiple transceivers

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 transceiverprovides 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.

Wireless monitoring and profiling of reactor conditions using plurality of sensor-enabled RFID tags having known locations

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.
