INSTALLATION OF SENSORS

6.1 Mounting substances

In order to obtain meaningful measurement data, the HTX Heat Flux

Sensor has to be mounted with adequate mounting substances. Adequate

mounting substances features are high thermal conductivity and low

thickness. Three types of mounting substance are suitable: adhesive tape,

thermally conductive paste, and thermally conductive glue.

The mounting substance should be chosen based on the measurement

setup.

Adhesive tape

Adhesive tape should be used for simple tasks, where quick setup is crucial

and the thermal coupling is of secondary importance.

Clean the surface to be measured and apply the tape to the backside of

the Sensor. Mount the Sensor onto the surface by applying gentle pressure

to establish adhesion. You can add a thermal paste (see the next section)

for improving thermal coupling to the surface.

Thermally conductive paste

Thermally conductive paste is recommended in applications where

pressure is used to fix the HTX Heat Flux Sensor in the measurement setup.

It generates a very strong thermal coupling as the paste adapts to the

surface inhomogeneities.

Clean the surface to be measured and spread a thin layer of paste onto the

backside of the Sensor. Then press the Sensor onto the surface. You may

need to hold the Sensor in place with tape across the electric cables.

Thermally conductive glue

Thermally conductive glue is suitable for applications where additional

mechanical stability is required. Similar to the paste, it generates a strong

thermal coupling and adapts to surface inhomogeneities.
