Catalytictype gas sensor consist of two elements: a detector element (D) which contains catalytic material and is sensitive to combustible gases, and a compensator element (C) which is inert. Combustible gases will burn only on the detector element, causing a rise in its temperature and, as a consequence, a rise in its resistance. Combustible gases will not burn on the compensator—its ...

The sensor itself is quite simple in design ...

20171002· This kind of gas sensor is engineered on the basis of the catalytic combustion (oxidation). Here is how it works: combustible gas mixtures start burning when they reach their ignition temperature. In the presence of some chemicals, a gas molecule oxidizes at a lower than regular ignition temperature, which speeds up the process. Some metal oxides and their compounds have excellent …

Catalytic combustion sensors are classified according to the method employed to measure combustible gas, and they have come to be widely used to prevent methane explosions in coal mines from about 1959. Since then, they have been improved considerably and are now more widely used throughout various industrial sectors as reliable sensors. Accuracy and reproducibility are excellent; …

Catalytic combustion gas sensors have been widely used for many years to detect flammable gases because of their simple structure, low cost, good stability and antipoisoning properties. In the traditional catalytic combustion gas sensor, the porous catalyst adhered on a platinum coil, which is employed as heater and thermistor simultaneously. The resistance of the catalyst layer influenced ...

Catalytic gas detectors require a routine “check” every 90days. While no routine calibration is actually required for IR detectors, a gas check is still recommended every 90days. Typically, calibration takes between 1 – 3 minutes. Should a catalytic sensor require replacement, it can easily be changed out in the field. IR point detectors require factory repair, however repair frequency ...
