Thermopiles — Kanthal®

A thermopile generator generates electrical energy from heat. A typical application is flame failure. In a gas water heater, gas fireplace or gas stove a thermopile generator produces voltage while a pilot light is lit. Once the pilot light is extinguished, the voltage drop triggers a valve shutting off gas supply to the appliance. Send a message. Kanthal® is a world-leading brand for products and services in the area …

Thermopile and Infrared Temperature Sensors | TE Connectivity

Thermopile IR Temperature Sensors. Thermopile sensors are designed to measure temperature from a distance by detecting an object's infrared (IR) energy. The higher the temperature, the more IR energy is emitted. The thermopile sensing element, composed of small thermocouples on a silicon chip, absorb the energy and produce an output signal. A ...

What is a Thermopile? (with pictures) - InfoBloom

A thermopile is a thermoelectric device that consists of an array of thermocouples connected in series. It is widely used in non-contact temperature measurement applications and temperature monitoring systems. Thermopiles detect the temperature of an object by absorbing the infrared radiation that emits from the object’s surface. Most of the device's detectors are equipped with a black body surface for …

Thermometrics Thermopile IR Sensor Applications

A thermopile is a serially-interconnected array of thermocouples, each of which consists of two dissimilar materials with a large thermoelectric power and opposite polarities. The thermocouples are placed across the hot and cold regions of a structure and the hot junctions are thermally isolated from the cold junctions. The cold junctions are typically placed on the silicon substrate to provide effective heat sink. In the hot …

Thermal Infrared (IR) Detectors: Pyroelectric Detectors and …

Thermopile detectors are composed of several thermocouples typically connected in series or, less commonly, in parallel. They are DC-type detectors and, thus, best suited for non-contact temperature measurement. These thermopile sensors are based on silicon micromachining technology. A special IR-absorption layer covers the hot junctions creating the sensor's sensitive area. The output of a …

Thermopile detectors - Hamamatsu

thermopile detectors have many thermocouples that are serially connected on a silicon substrate. The hot junction side (photosensitive area) is designed to be a thermally isolated structure, so heat generation caused by light absorption is kept to the membrane (thin film), increasing the temperature difference between the hot junction and cold junction. An infrared absorption film is attached to the membrane to …
