Thermopile Detectors

Excelitas is a highly-rated provider of efficient thermopile detectors for peak performance in non-contact temperature measurements, thermometry, and gas monitoring. Our thermopile solutions have patented construction for optimal performance and measurement accuracy, even under thermal shock conditions.

Thermopile detectors are types of thermal detectors that make use of the Seebeck Effect, also known as the thermoelectric effect. The Seebeck Effect describes the ability of an object to generate a small thermal electromotive force in proportion to the detected infrared light energy. Using the Seebeck Effect, thermopile detectors can be used to measure the surface temperatures of particular objects or gas concentrations using non-dispersive infrared (NDIR) spectroscopy through non-contact means.

Excelitas proudly offers a wide range of thermopile detector solutions with different windows and optics. These include the following:

• TPD 1T 0122 Miniature Thermopile Detectors - feature a miniature sensor solution with a sensitive Chip and small optical window, which is optically coated in the IR band 5-14 µm and is available in two different formats.

• TPD 1T 0623 and TPD 1T 0625 High-Sensitivity Thermopiles - feature high-sensitivity sensing chips that can be used for general-purpose thermometric applications. Available in two different housing types, with varying optical windows, and include a thermistor for temperature compensation.

• TPD 2T 0625 Dual-Output Thermopile Detector - features two sensitive detection chips behind individual optical filter windows in a robust TO-39 housing.

• TPiD 1S 0121, TPiD 1S 0222 Thermopile Detectors SMD - has two sensitive chips in two distinct SMD housing sizes. The smaller version was manufactured with space efficiency in mind, while the larger version is used for higher sensitivities. Both have an internal thermistor that serves as a temperature reference for thermopile temperature compensation.

• TPiD 1T 0122 L3.0 Miniature Thermopile with Integrated Lens - features a compact TO-46 housing and integrated focusing lens, including a thermistor and thermopile.

• TPiD 1T 0122B, TPiD 1T 0222B ISOthermal Detectors - feature a unique housing concept with a sensitive chip and small optical window.

• TPiD 1T 0224, TPiD 1T 0624 Thermopile Detectors TO-39 - contain a sensitive chip and small aperture optical window. This series provides exceptional ISOthermal performance for improved thermal shock resistance.

• TPiD 1T 0226 IRA Thermopile with Integrated Reflector - available in IRA high metal can, which includes an integrated reflector for collecting the radiation receipt.

• TPiD 1T 0226 L5.5 Thermopile with Lens - an integral lens with integrated optics, which focuses radiation towards the sensitive chip for improved performance.
