what are thermopile
What is a thermopile and how do I use a thermopile with NI hardware like DAQ devices or modules? Solution: A thermopile is an array of several thermocouples connected in series. A thermopile with N thermocouples will output a voltage N times bigger than the one produced by a single thermocouple, increasing the sensitivity of the transducer. With enough elements in the thermopile, a useful voltage can be generated in order to control another process. This type of transducer is often used to measure heat flux. Depending on the voltage specification of the thermopile, it can be used with either a temperature input or a voltage input device.
