What is a thermopile? A detailed explanation of the question.
An explanation of non-contact temperature sensors using thermopile technology and why temperature can be measured without contact.
(Excerpt) <Introduction> - Why can temperature be measured without contact? All objects emit radiant energy based on absolute temperature, and by measuring this radiant energy, temperature can be measured without contact. Radiant energy has no wavelength dependence and has the property of being absorbed by black objects. When an object absorbs energy, its temperature rises. By measuring this temperature rise, it is equivalent to measuring the temperature of the object itself. The thermopile element introduced here is a type of thermocouple. Non-contact thermometers (sensors) that utilize thermopiles are also referred to as "radiation thermometers (sensors)." While a typical sensor contains only one element, this product contains multiple elements aligned within the sensor. Additionally, each element inside the sensor can capture the temperature distribution within the field of view by looking in different directions through the optical system. 【Features】 ■ Created with a thermopile ■ Two types of component types are available: "Sensor" and "Module" *For more details, please refer to the PDF document or feel free to contact us.
