Ukuqhathaniswa kweHlikihla isitokisi somthwalonobuchwepheshe bezinzwa zedijithali
Kokubili amangqamuzana e-capacitive kanye nama-strain gauge umthwalo amaseli ancike ezintweni eziningi ezidume ekuphenduleni komthwalo ukuze zilinganiswe.
Izinto ezibonakalayo ze-exAstic zivame ukuba yi-aluminium yezindleko eziphansi zomthwalo kanye nensimbi engenasici ngamaseli omthwalo ezindaweni ezonakele zezimboni.
Izinzwa zeCapacitive Gauge Sensors zikala ukuguquguquka kwezinto zokunwebeka ngawodwana ngawodwana, futhi umphumela wezinzwa uguqulwa ngumjikelezo we-elekthronikhi ohlelweni omelela umthwalo.
Inzwa ye-capacive ngumqhubi weqembu elibekwe ebangeni elincane ukusuka entweni elastic kanye nezinyathelo zokuxhumana ngaphandle kokuxhumana ne-foil ethambile, ngenkathi i-gage ye-foil ehlekisayo, lapho i-strain gage iyinhlangano evuselelwa ngokuqondile ye-exAstic ydate , okuvame ukuhlangana nezinhlelo zokusebenza zezimboni.
Ukuzwela
Ngokwengeziwe, izinzwa ze-capacive zizwela kakhulu, ngoshintsho olungu-10% ku-capacitance, ngenkathi i-foil shurain gauges imvamisa inokushintshwa kwe-0,1% kuphela. Njengoba izinzwa ze-capacive zizwela kakhulu futhi ngenxa yalokho zidinga ukuguquguquka okuphansi okuphansi kwento elastic, i-strain entweni ebanzi yesitokisi se-casacive umthwalo amahlaselo esingu-5 kuye kwayi-10.
I-Wiring nokubopha uphawu
Ushintsho oluphezulu ku-Capacitance lusiza ukuhlinzeka ngesiginali yokuphuma yedijithali, okuyi-capacitive umthwalo amaseli isibonakaliso esisheshayo esiveza ngqo umthwalo ku-g, kg, noma amasha. Ikhebula elibiza kakhulu le-coaxial elinamandla okuxhumeka we-wire-wire okuvaliwe isixhumi se-imithwalo futhi idlulisela isibonakaliso esinejubane ledijithali emuva kwithuluzi, elingase libe namakhulu amamitha kude. Ku-analog strain strain gauge umthwalo iseli, ukuhlinzekwa kwamandla kanye nezingeniso eziphansi ze-analog kuvame ukwenziwa kwinsimbi ngentambo ye-6 wire ebizayo lapho isiginali ye-analog iguqulwa ibe yidijithali. Esitokisini se-digital strain gauge umthwalo iseli, ukuguqulwa kwe-amplifier kanye / d kufakwa ezindlini, futhi amanani edijithali kanye nezimpawu zedijithali zivame ukwenziwa ukuze kusetshenziswe izintambo ezi-6 noma ezi-7.
