About The Infrared Thermopile

Thermopile is a kind of pyroelectric infrared sensor. It is a device composed of thermocouple. At present, it is in the ear thermometers, radiation thermometer, electric oven, in the field of food, such as temperature detection, gained widespread application as the temperature detection device.

By the absorption of infrared radiation membrane is a kind of small thermal capacity, temperature rising film easily.

At the bottom of the close to the middle of the plate is a hollow structure, the structure design to ensure that the cold end and the temperature difference on temperature measurement.

Thermocouple is composed of polycrystalline silicon and aluminum, both in series connection.
