Dry Environments
1. Plot a graph of the temperature versus time characteristics of the process.
2. Divide the horizontal axis into 10 equal increments and draw verticals. Read
the temperature at each vertical.
A typical temperature profile. The average temperature is 350°C.
3. Divide the sum of the temperatures by 10 to calculate the average
temperature. Modify this temperature as follows:
4. Add 15% if the maximum temperature is reached in the first third of the
process.
5. Add 10% if the maximum temperature is reached in the first half of the
process.
6. Taking into account the process height and width restrictions, select a
barrier meeting or exceeding this temperature/time profile (see p. 22).
Wet Environments
The rate heat is absorbed into the thermal barrier is significantly influenced by the
For wet process environments, calculate the average temperature using steps 1
to 5 above, and then contact Datapaq for advice.
Thermal Barrier Location
During the process, the barrier should if possible be positioned away from the
probes or from the product being measured. Where necessary, position at the
top level of a rack to avoid dirt, fat, etc., falling on it.
