What is a Thermopile ?
A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Thermocouples operate...
How a 4 Wire RTD Works ?
4 Wire RTD Principle The most accurate lead wire configuration is the “true” 4-wire configuration. In a true 4- wire configuration, the resistance of the lead wires does not contribute...
Introduction to RTDs
Resistance Temperature Detectors (RTDs) rely on the predictable and repeatable phenomena of the electrical resistance of metals changing with temperature. The temperature coefficient for all pure metals is of the...
