The reason for multiple instruments is that it will allow for more information on the entire sheet to be provided to the client. The final area that makes sense for either imaging or pyrometers is in between the oven and the molding zone. This might not be available for all applications. However, some have an available area of open viewing of the plastic sheet.

This area would be the last zone before the plastic goes into the molding and cooling. It is the last place you can actually affect or adjust the process by knowing the temperature or profile of the plastic.

The pyrometer or thermal imager can be mounted onto the oven siding or onto the mold siding. It might have to be placed in a protective cabinet or jacket to provide cooling if the ambient is too hot surrounding the area.

This final area will allow for the final temperature eading of the plastic before it is molded and cooled, a process that has no sight view for pyrometers or imaging. Below is a picture of a typical thermoforming application.
