Between two solid materials

Fig. 7.2 Mounting between two solid materials.

Mounting instructions:

1. Ensure that both solid bodies have contact areas at least as large as the

HTX Heat Flux Sensor.

2. Ensure that the two solid planes are perfectly parallel to each other and

that the contact surfaces are flat, dry and free of dust and grease. Clean

the Sensor surface with ethanol or isopropanol. Do not use acids or alkali

for cleaning the Sensor.

3. Mount the Sensor with the positive side of the Sensor in the direction of

the expected positive heat flux.

4. Sandwich the Sensor between the two contact areas using any of the

above described mounting substances. It is highly recommended to use

thermally conductive paste or glue to increase the quality of the thermal

contacts between the surfaces and the Sensor.

Do not use too much thermal paste or glue as it increases the risk of

thermal short-cuts between the two contact surfaces. Furthermore, ensure
