A high temperature data logger
Many industries need to monitor heaters’ or ovens’ temperature over time. Most companies employ high temperature data loggers and/or temperature chart recorders since even small temperature changes, if unnoticed, can cause serious problems. Installing and operating a high temperature data logger (tips) Installation and set-up may require no more than an hour from the moment you take a high temperature data logger out of its box to the
moment it becomes operational. This largely depends on make and model being used. Some data loggers require programming which can require a
great deal of effort especially if you must learn how the software works.
Here are a few things you should keep in mind during the purchase and the installation:
(1) A high temperature data logger will not display the collected information at the site but will need a PC to view the data;
(2) If you chose a temperature chart recorder, you will be able to view the collected information at the site but will have to spend some time changing the chart and pen periodically;
(3) Make sure that you’ve chosen the right kind of sensors. There are different types of sensors for different temperature levels. For high temperature applications a thermocouple is most often used;
(4) Have the sensors calibrated by a calibration;
(5) Remember to set the proper logging rate, which can vary depending on what process you are monitoring. It will make a large difference if you are logging temperature once every 15 seconds as opposed to once an hour;
(6) Most all data loggers store information digitally where as chart recorders record information in an analog format. Temperature chart recorders – use “paper-and-pencil” to record the temperature and their mechanical mechanisms are subject to wear and tear and will eventually fail and require repair or
