Thermopiles are generically defined as devices that convert thermal energy into electrical energy. That’s true. That’s accurate. Yet it’s also not very descriptive. That’s why we’ve created this brief video. It explains the basics of what our thermopiles are – and how they work. Enjoy!
All objects above absolute zero radiate electromagnetic energy. Our thermopile traps this energy and produces a voltage output proportional to the incident power without having to touch the object it is measuring. Power measurement thus becomes as simple as selecting a suitable optical or IR window to limit the incoming radiation to your area of interest.
All elements and compounds absorb light or energy at some point along the electromagnetic spectrum. To measure gasses we’re simply taking advantage of the unique and specific wavelengths where molecular absorption and resonance occur.
