Understanding Thermopile Infrared
نویسنده
چکیده
The thermocolumn or thermopile comprises a series of thermoelements, each element being a thin wire made of two materials of different thermal activity. When a temperature difference occurs between the two ends of a wire, an electrical tension thermotension, develops. Connecting several thermoelements in series adds together the thermotension of each element, producing a useful electrical output signal.

Infrared Thermopile Temperature Measurement Technique in Microwave Heating Systems
Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...
متن کاملDevelopment of a thermopile infrared sensor using stacked double polycrystalline silicon layers based on the CMOS process
A stacked double-layer (SDL) thermopile-based infrared sensor, which comprised of 96 thermocouples on a suspended membrane, has been designed and fabricated with a CMOS-compatible process. The thermoelectric properties were characterized, and responsivity (Rs) of 202.8 V W−1 and detectivity (D∗) of 2.85∗108 cm Hz1/2 W−1 for a SDL thermopile were derived. (Some figures may appear in colour only ...
متن کاملAn Inverse Linearization Model for the Characterization of Non-contact Thermopiles
A thermopile is an electronic device that converts thermal energy into electrical energy by means of arrangements of thermocouples that are connected in series. In addition, optical filters restrict the wavelength that strikes the thermopile. One of the main advantages of using a thermopile is its sensitivity to infrared radiation, which allows implementing non-contact thermometers. However, th...

The purpose of our study is to investigate the heat distribution and the occurring temperatures during grinding. Therefore, we did both experimental and numerical investigations. In the first part, we present the integration of an infrared thermopile array in a steel workpiece. Experiments are done by acquiring data from the thermopile array during grinding of a groove in a workpiece made of st...
متن کاملMeasurements of temperature distribution using an infrared optical fiber during radiofrequency ablation
In this study, we have measured temperature distribution using infrared optical fibers during radiofrequency ablation (RFA). Infrared radiations generated from the water around inserted electrode are transferred by silver halide optical fibers and are measured by a thermopile sensor. Also, the output voltages of a thermopile sensor are compared with those of the thermocouple recorder. It is exp...
