termopililämpömittarit
Termopililämpömittarit, also known as thermopile thermometers, are a type of non-contact temperature measurement device. They operate on the principle of the Seebeck effect, where a voltage is generated in a conductor when there is a temperature difference across it. A thermopile is essentially a collection of thermocouples connected in series. Each thermocouple consists of two dissimilar metal wires or semiconductors joined at two junctions. When the junctions are at different temperatures, a small voltage is produced. By connecting many such thermocouples, the cumulative voltage is amplified, making it easier to measure.
These thermometers are widely used for measuring the infrared radiation emitted by an object. All objects with
