Combustion Analyzer

Abstract

A combustion analyzer unit includes an array of primary sensors in the analyzer unit operably connected to a primary probe. The distal end of the primary probe is configured for insertion into a combustion system flue to conduct gas to the primary sensors for diagnosing and maintaining the furnace. An optional integrated CO sensor in the combustion monitor housing for sensing CO in the space adjacent to the furnace and flue and a removable CO monitor is detachably integrated into the combustion analyzer unit housing to be worn or carried by the technician during furnace testing and maintenance.

We claim: 
     
         1 . A combustion analyzer system comprising:
 a combustion analyzer unit having a gas inlet, a moisture elimination system, a controller and a primary sensor assembly, the controller is operably connected to the primary sensor assembly, the moisture elimination system and a dock for a removable carbon monoxide sensor unit;   a primary probe operably connected to the combustion analyzer via a cable with an internal hose for conducting flue gas from the distal end of the primary probe to a primary sensor assembly in the combustion analyzer unit;   a removable carbon monoxide sensor unit operably connected to the dock of the combustion analyzer unit with a carbon monoxide sensor operable to measure carbon monoxide concentrations in the vicinity of the removable carbon monoxide sensor.   
     
     
         2 . The combustion analyzer system of  claim 1  further comprising:
 a second carbon monoxide sensor in the combustion analyzer unit operable to measure carbon monoxide concentrations in the vicinity of the combustion analyzer unit. 
 
     
     
         3 . The combustion analyzer system of  claim 1  wherein the primary sensor assembly further comprises:
 a plurality of sensor slots for removable sensor units. 
 
     
     
         4 . The combustion analyzer system of  claim 3  wherein the plurality of sensor slots are poka-yoke mechanical interfaces. 
     
     
         5 . A combustion analyzer system comprising:
 a combustion analyzer unit having a gas inlet, a moisture elimination system, a controller and a primary sensor socket, the controller is operably connected to the primary sensor socket, the moisture elimination system and a dock for a removable carbon monoxide sensor unit;   a primary probe operably connected to the combustion analyzer via a cable with an internal hose for conducting flue gas from the distal end of the primary probe to a primary sensor socket in the combustion analyzer unit;   a removable carbon monoxide sensor unit operably connected to the dock of the combustion analyzer unit with a carbon monoxide sensor operable to measure carbon monoxide concentrations in the vicinity of the removable carbon monoxide sensor; and   a sensor assembly configured to removably engage the primary sensor socket to provide a plurality of gas sensors.   
     
     
         6 . The combustion analyzer system of  claim 1  further comprising:
 a second carbon monoxide sensor in the combustion analyzer unit operable to measure carbon monoxide concentrations in the vicinity of the combustion analyzer unit.
