Chapter 3 Catalytic Combustible Gas Sensors

Chapter 3 Catalytic Combustible Gas Sensors mass which helps make it resistant to shock and vibrations. Most importantly, the catalyst coating reduces the temperature needed to achieve a stable signal for hydrocarbons between 400°C and 600oC. The use of fine diameter wire not only reduces the size of the sensor, but it also increases the signal, because finer wire has a higher magnitude of ...

Which Combustible Gas Sensor is Right: Catalytic Bead or ...

20200327· Combustible gas sensors can be designed with two different technologies, catalytic bead sensors or infrared sensors. Catalytic bead sensors detect gas by burning gas molecules on a sensor element. Comparatively, infrared sensors absorb hydrocarbon gas through infrared light at specific frequencies. Learn the advantages of either sensor to find out which technology is best for your work ...

Understanding Combustible Sensor Performance

combustible sensor elements are usually enclosed in a robust stainlesssteel housing. Gas enters the sensor by first passing through a sintered, stainless steel flame arrestor. The sintered flame arrestor tends to act as a physical barrier that slows or inhibits the free diffusion of gas molecules into the sensor. The smaller the molecule, the more readily it is able to diffuse through the ...

Infrared LEL Gas Sensors – Risk or Reward?

20170807· The response of the catalytic bead sensor to combustible gas is inherently linear; there is a close correlation in the response of various gases with respect to the calibration gas. Response factors for catalytic bead sensors are typically less than two. The response of the IR sensor is nonlinear and only becomes linear once the sensor is characterized to a particular gas. Response factors ...

Combustible Gas Sensor Safety Sys

Combustible Gas Detectors. A combustible gas is any gas that will burn. Mixtures of combustible gases with air, when ignited, produce an explosion. Use a combustible gas detector to insure that the percentage of gas in the air can never get high enough for the mixture to burn. When gas is sensed, try to replace the gas/air mixture with fresh air. If this cannot be accomplished, then shut down ...
