High-Temperature Environment Thermal Measurements - Sensors …

In contrast, MEMS thermopile sensors are smaller and more economical. In addition, they provide low noise measurements and don’t require bias voltage or current. Inherently stable and with the ability to respond to a broad range of infrared radiation, MEMS thermopile sensors are thus the rugged, reliable choice for temperature detection and control. This explains their enormous potential in a variety of …
