Gas detectors are sensitive devices that can be affected by environmental conditions. There are times when a gas sample to be analyzed exists in an environment with temperatures that are too extreme for direct sensor placement. In some cases, extractive gas sampling is a better and more reliable method for the detection system. This new technical brief specifically discusses gas sample temperature conditioning and includes useful diagrams and examples for a better understanding of this topic:

• Heat Radiating from Tube when Cooling is Required
• Thermal Calculations for Sample Stream
• Inner Air Temperature
• Fluid Temperature vs. Distance from Inlet
