For the first time you can find all the information that is relevant to Heat Flux Sensors. This manual will explain how these sensors work and the many types that are available, including flat plate, thermogage, thin film type and Schmidt Boelter sensors. There is information on how to mount these sensors and the types of Amplifiers available to read the information and how to apply the output to everyday use.
The application notes section includes all manner of useful information, covering importance of emissivity, noise reduction and theoretical noise limits for heat flux measurement and absorbed vs. incident heat flux calibration.
In short a Heat Flux Sensor measures the heat transfer (loss or gain) through a surface. This information is conveyed in a simple form, so that the user can determine the amount of heat loss (or gain) through the surface of the material being tested.
Uses are many and varied, including how effective wall insulations are for buildings, the effect fires and flames have, heat applied in food preparation ovens, amount of heat escaping from furnaces and heat energy escaping from engines.
As it can be seen the temperatures involved in many of these applications can reach hundreds of degrees. For this reason, heat flux sensors have been developed to either withstand temperatures of up to 850°C. For applications for higher temperatures still, water cooled heat flux sensors are manufactured that have a cooling effect on the sensor.
