Hom Hom Sensors

Hom tshuaj tiv thaiv
Lub sensor resistive yog ib qho khoom siv uas hloov cov ntsuas lub cev xws li hloov chaw, deformation, quab yuam, acceleration, av noo, kub, thiab lwm yam. Feem ntau muaj cov resistive strain sensors, piezoresistive sensors, thermal sensors, thermal sensors, gas sensors, humidity sensors, thiab lwm yam resistive sensor Cheebtsam.
Resistance strain gauge
Qhov ntsuas ntsuas qhov ntsuas hauv qhov ntsuas tau muaj cov nyhuv hlau, uas yog, nws ua rau lub tshuab deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, kom tus nqi kuj hloov raws li. Feem ntau muaj ob hom kev tiv thaiv kab mob: hlau thiab semiconductor. Hlau strain gauge yuav muab faib ua hom hlau, ntawv ci hom thiab zaj duab xis hom. Lub semiconductor strain gauge muaj qhov zoo ntawm siab rhiab heev (feem ntau yog kaum ob lub sij hawm ntawm cov hlau hom thiab ntawv ci hom) thiab cov nyhuv transverse me me.
Piezoresistive yam
Piezoresistive sensor yog ib qho cuab yeej ua los ntawm diffusing tsis kam ntawm substrate ntawm cov khoom siv semiconductor raws li Piezoresistive nyhuv ntawm cov khoom semiconductor. Lub substrate tuaj yeem siv ncaj qha los ntawm kev ntsuas qhov ntsuas qhov ntsuas, thiab qhov sib txawv ntawm qhov sib txawv yog txuas nrog lub substrate hauv daim ntawv ntawm tus choj hluav taws xob. Thaum lub substrate undergoes deformation vim yog sab nraud quab yuam, qhov kev tiv thaiv qhov tseem ceeb yuav hloov, thiab tus choj yuav tsim cov khoom tsis sib npaug.
Lub substrate (los yog daim nyias nyias) cov ntaub ntawv siv rau piezoresistive sensors mas yog silicon wafers thiab germanium wafers. Silicon piezoresistive sensors ua los ntawm silicon wafers raws li cov ntaub ntawv rhiab heev tau txais kev saib xyuas ntxiv, tshwj xeeb tshaj yog cov khoom -xeev piezoresistive sensors uas ntsuas siab thiab tshaj tawm.
Thermal tsis kam
Thermal resistance temperature ntsuas yog raws li tus yam ntxwv uas tus nqi kuj ntawm ib tug hlau conductor nce nrog rau qhov nce ntawm qhov kub thiab txias rau qhov ntsuas kub. Feem ntau cov thermal resistors yog ua los ntawm cov khoom siv hlau ntshiab, nrog platinum thiab tooj liab feem ntau siv. Tsis tas li ntawd, cov ntaub ntawv xws li npib tsib xee, manganese, thiab rhodium tau pib siv los tsim cov thermal resistors.
