Excavator matsa lamba na firikwensin shine firikwensin da aka fi amfani dashi, kalma ce ta gabaɗaya don gano iskar gas, ruwa, ƙarfi da sauran abubuwa tsakanin makamashin inductive, shima ya haɗa da.
Manometers waɗanda ke auna karfin iska a sama da ma'aunin injin da ke auna matsa lamba a ƙasa. Akwai nau'ikan firikwensin ƙarfi da yawa, hanyar aunawa ta gargajiya ita ce yin amfani da nakasawa da matsuguni na abubuwan roba don bayyana kulawar injin alluran lantarki, amma girmansa yana da girma, mara nauyi, kuma abin da ake fitarwa ba na layi ba ne. Tare da ci gaban microelectronics basira, aikace-aikace na semiconductor kayan piezoresistive sakamako da kuma m elasticity, da ci gaban semiconductor karfi na'urori masu auna sigina, muhimmanci silicon piezoresistive da capacitive biyu, suna da kananan size, haske nauyi, high hankali abũbuwan amfãni, An yadu amfani da semiconductor karfi. na'urori masu auna firikwensin. Lokacin da semiconductor aka jaddada sama a kan crystal, da resistivity zai canza. Dangantakar da ke tsakanin canjin resistivity da danniya ana kiransa da semiconductor piezoresistive sakamako, kuma na'urar yawan firikwensin da aka yi na wannan tasirin ana kiransa firikwensin ƙarfi na piezoresistive, wanda ke da nau'i biyu, ɗaya shine firikwensin da aka yi da ma'aunin ma'aunin semiconductor wanda aka liƙa akan element na roba, wanda ake kira firikwensin piezoresistive pasted. Ɗayan ita ce juriyar watsawa da aka yi da fasahar da'irar da aka haɗa a kan ma'aunin abu na semiconductor, ta yadda ma'aunin damuwa da ma'aunin siliki suka zama firikwensin gaba ɗaya, wanda ake kira firikwensin piezoresistive. Yana da halaye na babban hankali, babban madaidaici, ƙananan ƙananan, nauyi mai nauyi, babban aiki na mita, tsari mai sauƙi, aiki mai dogara da tsawon rai.
