2. Catalytic bead sensor - Wikipedia

   en.wikipedia.org/wiki/Catalytic_bead_sensor

   Passing combustible gas raises the temperature further which increases the resistance of the platinum coil in the catalysed bead, leading to an imbalance of the bridge. This output change is linear, for most gases, up to and beyond 100% LEL , response time is a few seconds to detect alarm levels (around 20% LEL), [ 1 ] at least 12% oxygen by ...

   More robust sensors for use in high risk environments may have solid steel housing with a gas port of sintered metal granules. [2] Both of these work in a manner similar to the Davy safety lamp ; gas may percolate through the permeable mesh, but the passages are too long and narrow to support the propagation of a flame.

5. Thermal conductivity detector - Wikipedia

   en.wikipedia.org/wiki/Thermal_conductivity_detector

   The thermal conductivity detector (TCD), also known as a katharometer, is a bulk property detector and a chemical specific detector commonly used in gas chromatography. [1] This detector senses changes in the thermal conductivity of the column eluent and compares it to a reference flow of carrier gas. Since most compounds have a thermal ...
