Thermopile laser sensor - Wikipedia

Thermopile laser sensors (Fig 1) are used for measuring laser power from a few µW to several W (see section ). The incoming radiation of the laser is converted into heat energy at the surface. This heat input produces a temperature gradient across the sensor. Making use of the thermoelectric effect a voltage is generated by this temperature gradient. ...

CS320: Digital Thermopile Pyranometer

For thermopile pyranometers, a thermopile is used within the instrument as the sensor, and the thermal gradients are measured across hot and cold areas (black and white). The radiation intensity is proportional to the temperature differences between the two sensing areas. Accuracy depends upon the sensitivity of the material used in the sensors, the response time, and the distortion ...

Thermopile Support: FAQs, Troubleshooting, Care & Maintenance

How long does a thermopile sensor last and how accurate does it remain over time? Thermopile sensors don’t have a specific life expectancy or degradation rate. As long as they are used correctly and maintained properly, thermopiles can last for years or even decades and remain in good working condition. The key is typically to just avoid damaging or contaminating the sensor surface ...
