Using Hardwired
Telemetry
In addition to the standard off-line analysis, real-time analysis by hardwired
telemetry is possible with Insight software when used with an intermittent or
periodic oven (a batch process).
Thus, with thermocouples trailing from the oven 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.
As an alternative to hardwired telemetry, and for continuous processes where the
logger must travel through the oven, the optional Datapaq TM21 radio-telemetry
For processes requiring more than the eight data channels available with a single
MultiPaq21 logger, Insight has the capability to gather and analyze data by
hardwired telemetry from up to three loggers simultaneously (see p. 54).
To use multiple loggers with hardwired telemetry, all loggers must be connected to
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. 35), 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.
• There will normally be no need to use a thermal barrier to protect the
logger.
• 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.
