Masu watsa matsi sune mahimman abubuwan da ke cikin aikace-aikacen masana'antu waɗanda ke auna adadin jiki marasa lantarki, kamar zazzabi, matsa lamba, gudu, da kwana. Yawanci, 4-20mA transmitters suna zuwa nau'i uku: masu watsa wayoyi hudu (wayoyin samar da wutar lantarki guda biyu da wayoyi masu fitarwa guda biyu), masu watsa wayoyi uku (nau'in fitarwa na yanzu da wutar lantarki suna raba waya daya), da masu watsa wayoyi biyu.
A cikin wannan labarin, za mu tattauna fa'idodin na'urorin watsa matsi na waya guda biyu, nau'in jigilar matsi wanda ya sami farin jini a cikin 'yan shekarun nan. Ga wasu mahimman fa'idodin na'urorin watsa matsi na waya biyu:
1. Karancin kamuwa da ma'aunin thermocouples na parasitic da ƙarancin wutar lantarki: Na'urorin watsa wutar lantarki mai nau'in waya biyu ba su da sauƙi ga parasitic thermocouples da ƙarancin wutar lantarki tare da wayar, wanda ke ba su damar amfani da wayoyi masu sirara marasa tsada. Wannan zai iya adana adadi mai mahimmanci na kebul da farashin shigarwa.
2. Rage shisshigi na lantarki: Lokacin da juriyar fitarwa na tushen yanzu ya yi girma sosai, ƙarfin lantarkin da filin maganadisu ya jawo cikin madauki na waya gabaɗaya ba shi da mahimmanci. Wannan shi ne saboda tushen tsangwama yana haifar da ɗan ƙaramin ruwa wanda za'a iya ragewa ta amfani da igiyoyi masu murɗa.
3. Tsawon tsayin igiyoyi: Tsangwama mai ƙarfi na iya haifar da kurakurai a cikin juriya mai karɓa. Koyaya, don madauki mai waya biyu na 4-20mA, juriya mai karɓar yawanci shine 250Ω, wanda shine ƙaramin isa don samar da kurakurai marasa mahimmanci. Wannan yana ba da damar tsayi da nisa tsayin kebul idan aka kwatanta da na'urorin telemetry na lantarki.
4. Sassauci a cikin zaɓin tashoshi: Za'a iya canza nau'ikan nuni guda ɗaya ko na'urorin rikodi tsakanin tashoshi daban-daban tare da tsayin kebul daban-daban ba tare da haifar da bambance-bambancen daidaito ba. Wannan yana ba da damar raba bayanan da aka raba da kuma sarrafawa ta tsakiya.
5. Gano kuskure mai dacewa: Yin amfani da 4mA don matakin sifili yana sa ya zama sauƙi don gano wuraren buɗewa, gajerun hanyoyi, ko lalacewar firikwensin (matsayin 0mA).
6. Sauƙaƙe don ƙara na'urorin kariya masu ƙarfi: Ana iya ƙara na'urorin kariya masu haɓaka cikin sauƙi zuwa tashar fitarwa ta waya guda biyu, yana sa ya fi aminci kuma ya fi juriya ga walƙiya da tashin hankali.
A ƙarshe, masu watsa matsi na waya guda biyu suna ba da fa'idodi da yawa akan sauran nau'ikan masu watsawa, kamar rage saurin kamuwa da cututtukan parasitic thermocouples da faɗuwar wutar lantarki, rage tsangwama na lantarki, tsayin igiya mai tsayi, sassauci a zaɓin tasho, gano kuskure mai dacewa, da ƙari mai sauƙi na ƙari. na'urorin kariya. Tare da waɗannan fa'idodin, masu watsa matsa lamba biyu na waya suna zama mafi shahara a aikace-aikacen masana'antu waɗanda ke buƙatar ma'aunin matsi mai inganci kuma abin dogaro.
