Gas analysis with thermal conductivity principle
Thermal conductivity measurement with optional infrared measurement and optional pressure compensation.
The principle of gas analysis of gas mixtures using thermal conductivity has been a well-known and well-researched measuring principle for more than 100 years. The basic structure is very simple. A gas/gas mixture is fed into a heated measuring element. The heating element is now heated to a constant temperature with a measuring current until a state of equilibrium is reached. The gas mixture now disturbs this equilibrium with its specific thermal conductivity. The sensing element cools down and the resistance changes. The specific thermal conductivity of the gas mixture can be determined via the change in resistance. In this way, conclusions about the composition can also be drawn.
With additional modules such as electrochemical oxygen sensors or other gas measuring devices, disturbance variables can be determined and calculated directly in the FTC electronics. In this way, a comprehensive and, above all, inexpensive gas analysis is obtained.
