How does a temperature sensor work?
The T-GAGE looks and operates as easily as an Expert photoelectric sensor. The T-GAGE is different in that it detects the infrared light energy emitted by objects instead of its own emitted light. That’s why it’s considered a passive device. The sensor uses a thermopile as a receiver element to detect the emitted infrared energy within its field of view. This information is measured and analyzed by an ASIC, and depending on the thermal contrast, an output is given.
