Hanyar haɗin firikwensin

Wayar da na'urori masu auna firikwensin ya kasance koyaushe ɗaya daga cikin tambayoyin da ake yawan tuntuɓar su a cikin tsarin siyan abokan ciniki. Yawancin abokan ciniki ba su san yadda ake waya da na'urori masu auna firikwensin ba. A haƙiƙa, hanyoyin sadarwar na'urori masu auna firikwensin iri ɗaya ne. Na'urori masu auna matsi gabaɗaya suna da waya biyu, waya uku, wayoyi huɗu da wasu tsarin waya biyar.

Tsarin firikwensin matsi mai waya biyu yana da sauƙi, kuma yawancin abokan ciniki sun san yadda ake haɗa wayoyi. Ana haɗa waya ɗaya zuwa ga madaidaicin sandar wutar lantarki, ɗayan kuma, wato, siginar sigina, ana haɗa shi da mummunan sandar wutar lantarki ta hanyar kayan aiki, wanda shine mafi sauƙi. Na'urar firikwensin matsa lamba uku na waya yana dogara ne akan tsarin wayoyi biyu, kuma wannan waya tana da alaƙa kai tsaye zuwa madaidaicin sandar wutar lantarki, wanda ya ɗan fi damuwa fiye da tsarin wayoyi biyu. Dole ne firikwensin matsi na waya huɗu ya zama abubuwan shigar wuta guda biyu, sauran biyun kuma sigina ne. Yawancin tsarin wayoyi hudu shine fitarwar wutar lantarki a maimakon 4 ~ 20mA, kuma 4 ~ 20mA ana kiran su matsa lamba, kuma yawancin su ana yin su zuwa tsarin waya biyu. Wasu daga cikin siginar siginar na'urori masu auna matsa lamba ba a ƙara su ba, kuma cikakkiyar fitarwa ita ce dubun millivolts kawai, yayin da wasu na'urori masu auna firikwensin suna da da'irar haɓakawa a ciki, kuma cikakken fitarwa shine 0 ~ 2V. Dangane da yadda ake haɗa kayan nuni, ya dogara da kewayon ma'aunin kayan aikin. Idan akwai na'ura mai dacewa da siginar fitarwa, ana iya auna shi kai tsaye, in ba haka ba, ya kamata a kara da'irar daidaita sigina. Akwai ɗan bambanci tsakanin firikwensin matsa lamba biyar da na'urar firikwensin waya hudu, kuma akwai ƙarancin firikwensin matsa lamba biyar akan kasuwa.

Na'urar firikwensin matsin lamba yana ɗaya daga cikin firikwensin da aka fi amfani da su. Na'urori masu auna matsa lamba na al'ada galibi na'urori ne na inji, waɗanda ke nuna matsin lamba ta hanyar gurɓacewar abubuwa na roba, amma wannan tsarin yana da girma cikin girma kuma yana da nauyi, kuma ba zai iya samar da fitarwar lantarki ba. Tare da haɓaka fasahar semiconductor, na'urori masu auna matsa lamba na semiconductor sun kasance. An kwatanta shi da ƙananan ƙararrawa, nauyi mai haske, babban daidaito da halayen zafin jiki mai kyau. Musamman tare da haɓaka fasahar MEMS, na'urori masu auna firikwensin suna haɓaka zuwa ƙaramin ƙarfi tare da ƙarancin wutar lantarki da ingantaccen aminci.
