Ụkpụrụ na-arụ ọrụ nke Thermopile Infrared Sensor - Mmetụta okpomọkụ

Mmetụta Thermoelectric (Mmetụta Seeebeck)

Ọ bụrụ na ihe abụọ dị iche iche ma ọ bụ ihe A na B nke nwere otu ihe mgbe ha na-arụ ọrụ dị iche iche, mgbe ejikọtara na njedebe na-ekpo ọkụ (Ebe Ọkụ Na-ekpo ọkụ), meghere na njedebe oyi (Oyi Junction Mpaghara), na okpomọkụ gradient n'etiti ọkụ. njedebe na oyi oyi bụ ΔT_HC, yabụ na njedebe oyi, a ga-enwe ike thermoelectromotive V_pụọ.

Mgbe ụzarị infrared nke dị n'èzí na-eme ka mpaghara absorption nke onye na-achọpụta ihe, mpaghara absorption na-amịkọrọ radieshon infrared ma gbanwee ya n'ime ike ọkụ.A ga-emepụta gradient okpomọkụ na mpaghara nkwụsị ọkụ na mpaghara nkwụsị oyi.Site na Seebeck Effect nke thermocouple ihe, enwere ike ịgbanwe gradient okpomọkụ ka ọ bụrụ mmepụta mgbama voltaji.
