The Sensor of the COe In-Line Flue gas probe AMS 3211-1600 is made of a electrochemical solid electrolyte sensor of partially stabilised Zircon dioxide ceramic.
The sensor has three electrodes:
- O2 sensitive Platinum electrode
- CO / H2 sensitive electrode made of Platinum / precious metal alloy
- Platinum reference electrode
The measurement of COe with the COe in-line flue gas probe AMS 3211-1600 is not a CO measurement in the classical sense. The flue gas probe AMS 3211-1600 measures in-situ the concentration of the sum of all combustible (oxidising) flue gas components such as CO and H2. The result of the measurement is displayed as COe. In applications with a known fuel at a constant composition the true CO concentration can be determined within limits. The COe in-line glue gas probe AMS 3211-1600 can be used for the measurement of O2 and Coe in natural gas, fuel oil # 4, lignite and hard coal.
The measuring range of the component COe is 1000 PPMv. For a quality measurement this range is quite sufficient, since the main purpose of the measurement is to avoid the generation of carbon monoxide. Due to the physical dimensions the sensor for measurement of O2 and COe can also be used with all other flue gas probes of AMS.
