1. An apparatus, comprising:
- at least one process element configured to measure at least one process variable associated with an industrial process being controlled;
a first transceiver configured to communicate with the at least one process element; and
a second transceiver configured to communicate wirelessly with the first transceiver;
wherein the second transceiver is further configured to communicate with a process control system that is configured to control the industrial process, the process control system configurable to;
(i) indirectly infer values of the at least one process variable based on measurements of at least one other process variable; and
(ii) receive direct measurements of the at least one process variable taken by the at least one process element and provided by the second transceiver and control the industrial process using the direct measurements.

Abstract
An apparatus includes at least one process element and a first transceiver configured to communicate with the at least one process element. The apparatus also includes a second transceiver configured to communicate wirelessly with the first transceiver and to communicate with a process control system. The process control system may transmit data to the at least one process element via the first transceiver and the second transceiver. The process control system may also receive data from the at least one process element via the first transceiver and the second transceiver.

19. A method, comprising:
-
identifying a process variable associated with an industrial process being controlled by a process control system, wherein values of the identified process variable are indirectly inferred based on measurements of at least one other process variable taken by the process control system; placing at least one process element in the industrial process, the at least one process element configured to directly measure the identified process variable; coupling the at least one process element to a first transceiver; receiving data from the at least one process element at the first transceiver, the data comprising direct measurements of the identified process variable; wirelessly communicating the data to a second transceiver; communicating the data from the second transceiver to the process control system; and controlling the industrial process at the process control system using advanced process control and optimization techniques and the direct measurements of the identified process variable. - View Dependent Claims (20)
