Tonse tikudziwa kuti chigawo chachikulu cha sikelo yamagetsi ndikatundu cell, womwe umatchedwa "mtima" wamagetsisikelo. Zinganenedwe kuti kulondola ndi kukhudzidwa kwa sensa kumatsimikizira mwachindunji ntchito yamagetsi amagetsi. Ndiye timasankha bwanji cell cell? Kwa ogwiritsa ntchito athu ambiri, magawo ambiri a cell cell (monga nonlinearity, hysteresis, creep, kutentha kwa chipukuta misozi, kukana kutsekereza, etc.) zimatipangitsa kuti tigonjetse. Tiyeni tiwone mawonekedwe amagetsi amagetsi za tiye zikuluzikulu luso magawo.
(1) Katundu wovoteledwa: kuchuluka kwa axial komwe sensor imatha kuyeza mkati mwazosankha zaukadaulo. Koma pakugwiritsa ntchito kwenikweni, nthawi zambiri 2/3 ~ 1/3 yokha yamitundu yovotera ndiyomwe imagwiritsidwa ntchito.
(2) Katundu wololeka (kapena wotetezedwa): kuchuluka kwa axial komwe kumaloledwa ndi cell yolemetsa. Kugwira ntchito mopitirira muyeso kumaloledwa mkati mwazosiyana. Nthawi zambiri 120% ~ 150%.
(3) Kuchepetsa katundu (kapena malire ochulukira): kuchuluka kwa axial komwe sensor yamagetsi imatha kunyamula popanda kuipangitsa kuti iwonongeke. Izi zikutanthauza kuti sensa idzawonongeka pamene ntchitoyo idutsa mtengowu.
(4) Sensitivity: Chiyerekezo cha kuchuluka kwa zotulutsa kuzomwe zimagwiritsidwa ntchito. Nthawi zambiri mV ya zotulutsa zovoteledwa pa 1V zolowetsa.
(5) Nonlinearity: Ichi ndi chizindikiro chomwe chikuwonetsa kulondola kwa ubale womwe umagwirizana pakati pa kutulutsa kwa siginecha yamagetsi ndi sensor yamagetsi ndi katundu.
(6) Kubwereza: Kubwerezabwereza kumasonyeza ngati mtengo wotuluka wa sensa ukhoza kubwerezedwa ndi kusinthasintha pamene katundu womwewo umagwiritsidwa ntchito mobwerezabwereza pansi pazikhalidwe zomwezo. Mbali imeneyi ndi yofunika kwambiri ndipo imatha kusonyeza bwino khalidwe la sensa. Kufotokozera za zolakwika zobwerezabwereza mu chikhalidwe cha dziko: cholakwika chobwerezabwereza chikhoza kuyesedwa ndi nonlinearity panthawi imodzimodziyo kusiyana kwakukulu (mv) pakati pa zizindikiro zenizeni za chizindikiro zomwe zimayesedwa katatu pa mfundo yoyesera yomweyi.
(7) Lag: Tanthauzo lodziwika bwino la hysteresis ndi: pamene katunduyo akugwiritsidwa ntchito pang'onopang'ono ndiyeno amatsitsidwa motsatizana, mogwirizana ndi katundu aliyense, ndithudi payenera kukhala kuwerenga kofanana, koma kwenikweni ndizofanana, mlingo wa kusagwirizana. imawerengedwa ndi cholakwika cha hysteresis. chizindikiro choyimira. Cholakwika cha hysteresis chimawerengedwa muyeso ya dziko motere: kusiyana kwakukulu (mv) pakati pa chiwerengero cha masamu cha mtengo weniweni wa chizindikiro cha mikwingwirima itatu ndi chiwerengero cha masamu a mtengo weniweni wa chizindikiro cha kuphulika katatu pa mayeso omwewo. mfundo.
(8) Kuchira ndi zokwawa: Kulakwitsa kwa sensa kumafunika kuyang'aniridwa kuchokera kuzinthu ziwiri: imodzi ndiyokwera: katundu wovotera amagwiritsidwa ntchito popanda kukhudza kwa masekondi 5-10, ndi masekondi 5-10 mutatsegula.. Tengani zowerengera, kenako lembani zotuluka motsatizana nthawi zonse kwa mphindi 30. Chachiwiri ndi kuchira kwa chiwombankhanga: chotsani katunduyo mwamsanga (mkati mwa masekondi 5-10), werengani mwamsanga mkati mwa masekondi 5-10 mutatha kutsitsa, ndiyeno lembani mtengo wotuluka panthawi ina mkati mwa mphindi 30.
(9) Kutentha kovomerezeka: kumatanthawuza nthawi zomwe zimagwira ntchito pa cell yolemetsa iyi. Mwachitsanzo, kachipangizo kakang'ono ka kutentha nthawi zambiri kamalembedwa motere: -20℃+ 70℃. Masensa otentha kwambiri amalembedwa kuti: -40°C-250°C.
(10) Kutentha kwa malipiro osiyanasiyana: Izi zikusonyeza kuti sensa yalipidwa mkati mwa kutentha kotereku panthawi yopanga. Mwachitsanzo, masensa abwinobwino amatenthedwa nthawi zambiri amalembedwa kuti -10°C - +55°C.
(11) Kukana kwa insulation: kukana kwamphamvu pakati pa gawo lozungulira la sensa ndi mtengo wotanuka, kukulirakulirako, kukula kwa kukana kukana kumakhudza magwiridwe antchito a sensa. Pamene kukana kwa kutchinjiriza kumakhala kotsika kuposa mtengo wina, mlatho sugwira ntchito bwino.
