The combustibles measurement you need to control your combustion process

How gas analyzers work to measure combustibles

Servomex’s Calorimetry sensor uses a four-quadrant bridge track, over-glazed to shield the circuit from the sample gas. Two quadrants are then coated in platinum catalyst; these quadrants form a Wheatstone bridge circuit, with the disc mounted in a cell heated to 300^oC (572^oF) or 400^oC (752^oF). When the gas sample is added, any COe present in the sample will combust on the catalyst, which will heat the respective quadrant and alter the Wheatstone bridge output voltage.

The output delivered will be directly proportional to the COe concentration, providing an accurate measurement.
