In situ flue gas analyzer with improved process communication
An in situ flue gas analyzer (10) includes a probe (12) extendable into a flue. The probe (12) has a measurement cell providing a signal responsive to a concentration of a gas within the flue. A controller (52) is coupled to the probe (12) and configured to provide an output based on the signal from...

Zusammenfassung: | An in situ flue gas analyzer (10) includes a probe (12) extendable into a flue. The probe (12) has a measurement cell providing a signal responsive to a concentration of a gas within the flue. A controller (52) is coupled to the probe (12) and configured to provide an output based on the signal from the measurement cell. A first media access unit (54) is coupled to the controller (52) and is operably coupleable to a first process communication link. The first media access unit (54) is configured to communicate in accordance with an all- digital process communication protocol. A second media access unit (56) is coupled to the controller (52) and is operably coupleable to a second process communication link. The second media access (56) unit is configured to communicate in accordance with a second process communication protocol that is different than the all-digital process communication protocol. The first and second media access units (54, 56) are enabled simultaneously. |
