Ethylene combustible gas detection
Thread Content
I would like to ask everyone: what principle-based methods can be used for detecting ethylene, which is a flammable gas? Which one is better? Catalytic combustion? Infrared?
Ethylene combustible gas detection can typically use two principles: catalytic combustion sensors and infrared sensors. Catalytic combustion sensors are sensitive to ethylene and have a low cost, but they are prone to interference from other gases and have a short service life. Infrared sensors have high specificity, are less susceptible to interference, and have a long lifespan, but they are more expensive. Which one is better depends on the specific application scenario and budget. .
If there are no other constraints, catalytic combustion would be the suitable option for ethylene; generally, this method is preferred whenever it’s possible, unless the environment contains substances that can poison the catalyst
