Furnace Temperature
Profiles: Creation and Use
A temperature profile can be acquired by two means:
• Without telemetry – After the logger and product have been in the
furnace, data is downloaded from the logger into the PC to be displayed and
analyzed by the Datapaq Insight software.
• Using telemetry – As the logger gathers data from the product inside the
furnace, this is transmitted directly to the PC by a hard-wired connection
(serial telemetry) or by radio transmitter/receiver (radio telemetry). The
temperature profile can be watched developing as it happens, i.e. in real
time. For the use of hardwired telemetry, see your dedicated logger User
Manual. For radio telemetry, see the TM21 Radio-telemetry System User
Manual.
This chapter describes all the stages of obtaining a temperature profile for a
product while it is in the furnace, without telemetry – from how and where to
place the probes, to downloading the data into the software, ready to be
analyzed.
Before running your product and the data logger through the furnace you will
use the Insight software to reset the logger, i.e. to prepare it for receiving fresh
data. After the logger has been retrieved from the furnace, you will use Insight
again to download the profile data and save it to disk.
In summary, the stages are as follows.
1. Choose positions for, and attach, the thermocouple probes.
2. Setup communication between the data logger and your PC (if this has
not already been done for a previous profile run).
3. Reset the data logger so that it is ready to receive fresh data; in the
process of doing this you will also be able to set the sample collection
interval and the method used to trigger the start of data collection, and to
check the logger's battery status.
4. Install the logger in its thermal barrier.
5. Run the product and logger/barrier through the furnace.
6. Download the data from the logger into the Insight software.
7. If necessary, set the furnace start position within the data.
8. Add any additional information that you wish to have recorded with the
profile data.
