Thermopile infrared (IR) Sensors. Thermopiles 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 reference sensor is designed into the package as a reference for compensation.
Standard and custom thermopile sensors are available. Thermopile infrared (IR) non-contact temperature measurement sensors are available with various lens, and filters allowing use in multiple applications, from industrial pyrometers, to climate controls and medical devices. Depending on the sensor, the output signal can be the standard resistance output, or packaged with analog or digital output signals. Various sensor packages are available including hermetically sealed housings, stainless steel packaged housings, and integral circuit boards and connectors. Custom thermocouple infrared sensors are available.
