Oxide humidity rhiab heev resistor kev ua tau zoo dua, tuaj yeem siv tau ntev, kev kub ntxhov me ntsis. , kuj thiab av noo hloov nyob rau hauv ib tug linear kev sib raug zoo.
3) photosensitive resistor. Feem ntau ntawm cov photoresistors yog ua los ntawm cov khoom siv semiconductor. Nws ua rau kev siv cov semiconductor' s photoconductive zog ua kom tus nqi ntawm cov resistor hloov nrog qhov siv ntawm qhov teeb meem teeb. Thaum qhov teeb meem teeb meem intensifies, tus nqi kuj txos obviously. Thaum qhov teeb meem teeb meem tsis muaj zog, tus nqi kuj nce ntau
4) Gas rhiab heev resistor. Cov roj rhiab heev yog tsim los ntawm REDOX cov tshuaj tiv thaiv tom qab nqus tau qee cov roj los ntawm qee qhov semiconductor. Lub ntsiab tivthaiv yog hlau oxide. Lub ntsiab ntau yam yog hlau oxide roj rhiab resistor, composite oxide roj rhiab resistor, ceramic gas rhiab resistor thiab hais txog.
5) Force rhiab heev resistor. Lub zog rhiab heev yog ib hom kev tiv thaiv nrog lub siab hloov pauv zoo nkauj, tuaj yeem ua rau ntau yam torque meter, semiconductor microphone, siab sensor, thiab lwm yam. hais lus, alloy quab yuam rhiab heev resistor muaj siab rhiab heev.
6) Thermistor. Tus nqi tsis kam ntawm lub thermistor yuav qhia cov kauj ruam hloov nrog kev hloov ntawm lub cev kub, uas muaj cov yam ntxwv ntawm semiconductor. Thermistor raws li qhov sib txawv kub coefficient yog muab faib ua qhov zoo kub coefficient thermistor (hu ua PTC thermistor) thiab qhov kub tsis zoo coefficient thermistor (hu ua NTC thermistor) O dhau ib qho kub (Curie temperature), tus nqi tsis kam ntawm PTC thermistor nrog qhov nce ntawm qhov kub thiab txias pom ib kauj ruam nce.
Feem ntau, organic polymer PTC thermistor yog tsim rau kev tiv thaiv overcurrent, thiab ceramic PTC thermistor tuaj yeem siv rau ntau lub hom phiaj.
