Insert distance
You can specify a minimum distance between the product surface and the first temperature spot
element to be included in the average temperature calculation. If the temperature spot element is within
or above the Insert Distance, the element will be excluded from the calculation.
Figure 5-2. Insert distance
This function may be useful if the temperature of the atmosphere above the product surface
significantly deviates from the temperature of the product itself, resulting in large temperature
gradients close to the product surface. By specifying an Insert Distance, temperature elements within
this region can be excluded from average temperature calculations.
The Insert Distance function can also be used to compensate for inaccuracies in the measured
temperature element positions, in order to make sure that elements above the product surface are not
included in the average temperature calculation. If, for example, temperature element positions are
measured with an accuracy of 10 mm, setting the minimum distance to at least 10 mm will guarantee
that sensors above the surface are not included in the average temperature calculations.
