Namhlanje siza kwabelana ngendlela yokugweba ukuba i-sensor isebenza ngendlela eqhelekileyo na.
Okokuqala, kufuneka sazi ukuba zeziphi iimeko ekufuneka sigwebe ukusebenza kweinzwaKukho amanqaku amabini ngolu hlobo lulandelayo:
1. Ubunzima obuboniswa sisalathisi sokulinganisa abufani nobunzima bokwenyani, kwaye kukho umahluko omkhulu.
Xa sisebenzisa ubunzima obuqhelekileyo ukuvavanya ukuchanekaisikali, ukuba sifumanisa ukuba ubunzima obuboniswa sisalathisi bahlukile kakhulu kubunzima bobunzima bovavanyo, kwaye inqaku le-zero kunye noluhlu lwesikali alunakutshintshwa ngokulinganisa, ngoko ke kufuneka siqwalasele ukuba ingaba i-sensor ayiphukanga. Kumsebenzi wethu wokwenyani, sidibene nemeko enjalo: isikali sokulinganisa iphakheji, ubunzima bephakheji yephakheji yokutya yi-20KG (ubunzima bephakheji bunokubekwa njengoko kufuneka), kodwa xa ubunzima bephakheji bujongwa ngesikali se-elektroniki, Nokuba ngaphezulu okanye ngaphantsi, okwahlukileyo kakhulu kumthamo ojoliswe kuwo we-20KG.
2. Ikhowudi ye-alamu ethi "OL" ivela kwisalathisi.
Le khowudi ithetha ukuba umntu utyebile kakhulu. Ukuba isalathisi sihlala sixela le khowudi, jonga ukuba inzwa isebenza kakuhle na
Indlela yokugweba ukuba i-sensor isebenza ngokwesiqhelo
Ukulinganisa ukumelana (Isalathisi sokuCima uxhulumaniso)
(1) Kungaba lula kakhulu ukuba kukho incwadi yemiyalelo yenzwa. Okokuqala sebenzisa i-multimeter ukulinganisa ukumelana kokungena kunye nokuphuma kwenzwa, uze uyithelekise nencwadi yemiyalelo. Ukuba kukho umahluko omkhulu, iya kwaphuka.
(2) Ukuba akukho ncwadana, linganisa ukumelana kokufaka, okukuko ukumelana phakathi kwe-EXC+ kunye ne-EXC-; ukumelana kwemveliso, okukuko ukumelana phakathi kwe-SIG+ kunye ne-SIG-; ukumelana kwebhulorho, okukuko i-EXC+ ukuya kwi-SIG+, i-EXC+ ukuya kwi-SIG-, ukumelana phakathi kwe-EXC- ukuya kwi-SIG+, i-EXC- ukuya kwi-SIG-. Ukuxhathisa kokufaka, ukumelana kwemveliso, kunye nokuxhathisa kwebhulorho kufuneka kwanelise olu lwalamano lulandelayo:
"1", ukumelana nokufaka ＞ ukumelana nokukhupha ＞ ukumelana nebhulorho
"2", ukumelana kwebhulorho kuyalingana okanye kuyalingana.
Ukulinganisa i-voltage (isalathisi sinamandla)
Okokuqala, sebenzisa i-multimeter ukulinganisa i-voltage phakathi kwe-EXC+ kunye ne-EXC- terminals zesalathisi. Le yi-voltage yokukhupha i-sensor. Kukho i-DC5V kunye ne-DC10V. Apha sithatha i-DC5V njengomzekelo.
Uvakalelo lwemveliso yee-sensors esizichukumisileyo ngokubanzi yi-2 mv/V, oko kukuthi, isignali yemveliso ye-sensor ihambelana nolwalamano oluthe ngqo lwe-2 mv kwi-voltage nganye ye-1V yokukhupha.
Xa kungekho mthwalo, sebenzisa i-multimeter ukulinganisa inani le-mv phakathi kwemigca ye-SIG+ kunye ne-SIG. Ukuba imalunga ne-1-2mv, oko kuthetha ukuba ichanekile; ukuba inani le-mv likhulu kakhulu, oko kuthetha ukuba i-sensor yonakele.
Xa ulayisha, sebenzisa ifayile ye-mv ye-multimeter ukulinganisa inani le-mv phakathi kweengcingo ze-SIG+ kunye ne-SIG. Iya kwanda ngokulingana nobunzima obulayishiweyo, kwaye ubuninzi yi-5V (i-voltage yokukhupha umoya) * 2 mv/V (uvakalelo) = malunga ne-10mv, ukuba akunjalo, Oku kuthetha ukuba i-sensor yonakele.
1. Ayinakudlula uluhlu
Ukuqhuba ixesha elide kakhulu kuya kubangela umonakalo ongenakuguqulwa kumzimba othambileyo kunye ne-strain gauge ngaphakathi kwe-sensor.
2. Ukuwelda ngombane
(1) Nqamula intambo yesignali kwisilawuli sokubonisa ubunzima;
(2) Ucingo oluphantsi lwe-welding yombane kufuneka lubekwe kufutshane nenxalenye edibeneyo, kwaye i-sensor akufuneki ibe yinxalenye yesekethe ye-welding yombane.
3. Ukufakwa kwentambo yenzwa
Ukufakwa kwe-insulation yentambo yesensa kubhekisa kukumelana phakathi kwe-EXC+, EXC-, SEN+, SEN-, SIG+, SIG- kunye ne-shielding ground wire SHIELD. Xa ulinganisa, sebenzisa ifayile ye-multimeter resistance. Igiya ikhethwe kwi-20M, kwaye ixabiso elilinganisiweyo kufuneka lingabi nasiphelo. Ukuba akunjalo, isensa yonakele.
