Using Hardwired Telemetry; Running A Temperature Profile Using Hardwired Telemetry - Fluke Datapaq TP3 User Manual

Using Hardwired
Telemetry
In addition to the standard off-line analysis, real-time analysis by hardwired
telemetry (serial telemetry) is possible with Insight software when used with
an intermittent or periodic oven/furnace/kiln (a batch process).
Thus, with thermocouples trailing from the oven/furnace/kiln and attached to
the logger outside it, data being gathered by the logger is transmitted via the
communications lead directly to the PC, and the temperature profile can be
watched developing in the Insight software as data is received, i.e. in real time.
Some processes can have long durations. In these instances telemetry can allow
you to identify possible problems during the process, and make adjustments.
You can then use a second system to confirm that the remedial action has been
satisfactory.
You may alternatively run a real-time profile, with the logger outside the heat-
process, by using Bluetooth telemetry, which avoids any potential earth-loop
Use of the optional TM21 radio-telemetry system is described in its own
Running a Temperature Profile Using
Hardwired Telemetry
By following the procedure in this chapter, you will use the Logger Reset and
Logger Download dialogs to run a temperature profile using hardwired telemetry.
Running a profile in real time is performed in essentially the same way as a
normal (non-telemetry) run (see p. 41, and the dedicated User Manual for
your Datapaq Tracker system), but, in addition:
• The communications lead is left in place, connecting the PC to the logger.
• A process file can be applied before the run starts in order that the data
can be understood more readily as it appears on screen (not available with
Insight Furnace Surveying software).
• The logger will not normally enter the oven/furnace/kiln, so there is no need
to use a thermal barrier to protect it.
• While the run is in progress, the real-time display of incoming data can be
customized as preferred, and the logger's status can be checked.
