Thermal conductivity gas analyzer is an effective method to measure one of two components in a gas mixture (the thermal conductivities differ a lot). Mainly used to measure the content of hydrogen (H2), carbon dioxide (CO2), argon (Ar), etc.
When the sample gas enters the thermal conductivity cell which is heated at a constant temperature of 63°C, and a thermistor is used above the film to maintain a constant temperature of 135°C. In this way, a small cavity is formed below and above the membrane, and the measurement gas can diffuse into it. In this way, the heat loss caused by the thermal conductivity of the sample gas is compensated by heating, and the voltage required to maintain a constant temperature of the membrane is a measurement of the thermal conductivity of the measured gas.
• Measurement of hydrogen (H2) content in synthesis gas of ammonia plant
• Purity measurement of hydrogen (H2) in hydrogenation unit
• Measurement of oxygen (O2) in pure hydrogen (H2) and hydrogen (H2) in pure oxygen (O2) in the process of producing hydrogen by electrolysis of water and oxygen
• Hydrogen (H2) content measurement in hydrocarbon gas
• Monitoring of hydrogen (H2) and carbon dioxide (CO2) content in hydrogen-cooled generator sets
• Measurement of hydrogen (H2) in chlorine (Cl2) in the chlorine production process
• Measurement of chlorine (Cl2) in the chlorine production process
• Measurement of carbon dioxide (CO2) content in flue gas of furnace combustion
• Argon (Ar) content measurement in air separation plant
• Monitoring in the production of pure gases, such as helium (He) in nitrogen (N2) and argon (Ar) in oxygen (O2)
• Sulfur dioxide (SO2) content measurement in the production process of sulfuric acid and phosphate fertilizer
• Corrosion protection
Sensor surface is coated with Polymer layer(4µm) which will not affect the excellent measurement performance of the sensor unit.
• Condensation and dust protection
The sintered glass with µm-sized holes is used to protect the sensor so that gas molecules can pass through, but liquid water molecules are not permeable. In addition, the sintered glass protective layer also reduces the dependence on gas flow.
