Gas Sensor Sintered Flame-Arrestor Cap (IEC 60079-1 (Ex d) designs) is used for letting target gas diffuse to a catalytic or infrared sensor while the sintered metal cap stops a flame inside the sensor head from reaching the outside atmosphere.
How to Specify Gas Sensor Sintered Flame-Arrestor Cap
Porosity: Finer porosity (10–20 µm) gives better flame quenching but slower gas diffusion; the sensor maker specifies the window.
Material: SS316L sintered powder or multi-layer mesh, resistant to H2S and humidity.
Certification: The cap is part of the certified flameproof assembly — substitutes must be identical.
Materials
Standard supply is stainless steel 316/316L; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
Fitting & Care
Protect the cap from paint, oil mist and water spray with the sensor's weather guard.
Bump-test after cleaning or any physical impact.
Common Mistakes
Fitting a non-certified cap, which voids the Ex certification.
Letting dust or oil foul the cap, which slows response and under-reads concentration.
When Gas Sensor Sintered Flame-Arrestor Cap Is Not the Right Choice
Not a liquid filter or a dust filter for heavy particulate — use a separate pre-filter.
Gas Sensor Sintered Flame-Arrestor Cap is made to order as finished parts. Indicative pricing starts from about US$1.80 per piece for a standard size at production quantity; the final price depends on size, material, finish, tooling and order volume.

What is Gas Sensor Sintered Flame-Arrestor Cap used for?
Letting target gas diffuse to a catalytic or infrared sensor while the sintered metal cap stops a flame inside the sensor head from reaching the outside atmosphere.
Why do gas sensors use sintered metal caps?
The porous metal lets gas through but cools and quenches any flame, making the head flameproof.
Does a blocked sintered cap affect readings?
Yes — response slows and readings can be low; test and replace fouled caps.
Can I replace a gas sensor cap with any sintered filter?
No — only the certified part keeps the flameproof rating.
