An Introduction to Thermopile Detectors

An Introduction to Thermopile Detectors. A thermopile detector is a passive radiation sensing voltage-generating device. It does not emit any radiation and require cooling or bias. Dexter Research Center (DRC) provides stable, high output radiation sensing thermopile detectors covering linear dynamic range from the UV to long wave IR.

HFP03 ultra-sensitive heat flux sensor | Hukseflux

A thermopile is a passive sensor; it does not require power. Using HFP03 is easy. It can be connected directly to commonly used data logging systems. The heat flux in W/m² is calculated by dividing the HFP03 output, a small voltage, by the sensitivity. The sensitivity is provided with HFP03 on its calibration certificate.

Thermometrics Thermopile IR Sensor Applications

A theoretical limit of thermopile sensitivity will be determined when this noise is at its minimum. In this thermopile detector, Johnson noise of these many noise sources is a predominant electrical noise source. Since the device impedance for a typical thermopile detector is mainly resistive, the Johnson noise for a detector having a device

Miniature Thermopiles - Thermopiles - LASER COMPONENTS

The only requirement is that the radiation be absorbed in order to heat the detector. This effect is improved by the application of a black layer, and the spectral sensitivity is flat from the UV to the far IR range (exception: ST series). However, application is most widespread in the infrared spectral range. The thermopile is a DC detector.
