Application Notes
- AN-1952 Designing with Thermocouples (Rev. A)PDF, 72 Kb, Revision: A, File published: May 7, 2013
In 1821 Thomas Seebeck discovered the physical phenomenon that when you join two dissimilar metalson both ends and heat one end, a continuous current is created in the thermoelectric circuit . If the otherend is broken, a voltage can be measured that is proportional to the temperature difference between theheated junction (measuring or hot junction) and the open end (reference or cold ju - Low-Voltage Current Loop TransmitterPDF, 519 Kb, File published: Aug 2, 2007
