For example, many gas appliances use a thermocouple to detect temperature and control the flow of gas.

What is Thermopile? Size — Thermocouple have a thin construction while a thermopile is thicker in size. Voltage — While both devices can detect temperature, but a thermocouple has a lower temperature range than a thermopile.
Temperature type — The contact-based temperature can be measured by thermocouples, while a thermopile can usually become helpful in measuring the non-contact-based temperature. Design — A thermocouple is designed to use two types of wires that are of a different material.
Heat lies on the first wire and travels to reach the second wire. An instrument of extreme sensibility, used to determine slight differences and degrees of heat. It is composed of alternate bars of antimony and bismuth, or any two metals having different capacities for the conduction of heat, connected with an astatic galvanometer, which is very sensibly affected by the electric current induced in the system of bars when exposed even to the feeblest degrees of heat.
A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of Seebeck effect, and this voltage can be interpreted to measure temperature.
A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Published: 16 Jan, Thermocouple noun physics A transducer consisting of two different metals welded together at each end; a voltage is produced that is proportional to the difference in temperature between the two junctions one of which is normally held at a known temperature.
Thermopile noun An electronic device that converts thermal energy into electrical energy. Thermocouple noun A thermoelectric couple. Thermopile noun An instrument of extreme sensibility, used to determine slight differences and degrees of heat. Thermocouple noun a kind of thermometer consisting of two wires of different metals that are joined at both ends; one junction is at the temperature to be measured and the other is held at a fixed lower temperature; the current generated in the circuit is proportional to the temperature difference.
Thermopile noun a kind of thermometer for measuring heat radiation; consists of several thermocouple junctions in series. Thermocouple noun a thermoelectric device for measuring temperature, consisting of two wires of different metals connected at two points, a voltage being developed between the two junctions in proportion to the temperature difference.
Thermopile noun a set of thermocouples arranged for measuring small quantities of radiant heat. Thermocouple A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. Thermopile A thermopile is an electronic device that converts thermal energy into electrical energy. Thermocouple Illustrations. Thermopile Illustrations. Thermocouples are a widely used type of temperature sensor.
Commercial thermocouples are inexpensive, interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation. Thermocouples are widely used in science and industry. Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes.
Thermocouples are also used in homes, offices and businesses as the temperature sensors in thermostats, and also as flame sensors in safety devices for gas-powered appliances. A thermopile is an electronic device that converts thermal energy into electrical energy.
It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Thermocouples operate by measuring the temperature differential from their junction point to the point in which the thermocouple output voltage is measured.
It produces higher voltage output compare to single thermocouple. Moreover unlike thermocouple which is contact based temperature sensor, thermopile is non contact based temperature sensor device. It uses infrared radiation for temperature measurement along with IR Absorber device.
