Running a Temperature
Profile
A temperature profile can be acquired by two means:
• Without telemetry – After the logger and product have been in the
oven, data is downloaded from the logger into the PC to be displayed and
analyzed by the Datapaq Insight software.
• Using hardwired telemetry – As the logger gathers data from the
product inside the oven, this is transmitted directly to the PC by a
hardwired connection. The temperature profile can be watched developing
as it happens, i.e. in real time. See p. 63.
This chapter describes the stages of obtaining a temperature profile for your
process without telemetry – from placing the probes, to downloading the data
into the software, ready to be analyzed.
Overview
It is important to be aware of the key characteristics of the process you will be
profiling. These include:
• Line speed.
• Number of oven zones.
• Maximum temperature in each oven zone.
• Number, location and method of attachment of the thermocouple probes.
• The approximate temperature profile which the thermal barrier is expected
to experience.
• Height and width restrictions within the oven.
Before the logger is used for the first time with a given PC, you must:
1. Install Insight software (p. 13).
2. Establish communication between the logger and the computer/software
(p. 14).
Before running your product or test-piece, and the logger, through the oven
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 oven, you
will use Insight again to download the profile data and save it to disk. The
stages are as follows.
1. Choose positions for, and attach, the thermocouple probes (see p. 41).
