thermopile type micro flow sensor

Thermopile and Infrared Temperature Sensors | TE Connectivity

Thermopile sensors are designed to measure temperature from a distance by detecting an object's infrared (IR) energy. The higher the temperature, the more IR energy is emitted. The thermopile sensing element, composed of small thermocouples on a silicon chip, absorb the energy and produce an output signal. A reference sensor is designed into the package as a reference for compensation ...

Thermal and Coriolis type micro flow sensors based on ...

· An ambient temperature- gradient compensated flow sensor and an uncompensated single-microchannel flow sensor, for comparison, were measured, with both sensors having nearly equal amounts of thermopile junctions. The ambient temperature- gradient compensated flow sensor shows to be completely compensated for external temperature gradients (Fig. 3). The uncompensated flow sensor shows a figure-of-eight sensitivity pattern, because the sensor …
