Ungayenza njani i-Composishhoot

Inkqubo yokulinganisa ngombane ibalulekile kuwo onke amashishini, ezorhwebo kunye norhwebo. Kuba iiseli ezilambayo zizinto ezibaluleke kakhulu kwiinkqubo zokulinganisa, kufuneka zichaneke kwaye zisebenze ngokufanelekileyo ngamaxesha onke. Nokuba njengenxalenye yolondolozo olucwangcisiweyo okanye ukuphendula kwindawo yokusebenza, ukwazi indlela yokuvavanya aiselfowuniinokunceda ukwenza izigqibo ezinolwazi malunga nokulungisa okanye ukutshintsha izinto.
Kutheni le nto iiseli zemithwalo zisilela?

Iiseli zomthwalo zisebenza ngokulinganisa amandla azibhokoxeyo ngumqondiso wevolthi othunyelwe kumthombo wamandla olawulayo. Isixhobo senkqubo yokulawula, enjenge-Amplifier okanye iyunithi yoLawulo lweNtengiso, emva koko iguqula i-sign kwixabiso elilula lokufunda kumboniso lwesalathi sedijithali. Kufuneka benze phantse yonke indawo, enokuthi ngamanye amaxesha ibenza imiceli mngeni emininzi ekusebenzeni kwawo.

Le mingeni yenza ukuba iiseli zomthwalo zithambekele ekubeni singaphumeleli kwaye, ngamanye amaxesha, zisenokufumana imiba echaphazela intsebenzo yabo. Ukuba ukusilela kwenzekile, ngumbono olungileyo ukukhangela ukuthembeka kwenkqubo kuqala. Umzekelo, akuqhelekanga ukuba izikali zigcwaliswe kakhulu ngomthamo. Ukwenza njalo kunokuchaphazela iseli yomthwalo kwaye ube nomthwalo wothusa. Ukuchitheka kwamandla kunokutshabalalisa iiseli zomthwalo, njengoko kunokuyifumana umswakama okanye ichikisi yekhemikhali emngxunyeni wesikali.

Iimpawu ezinokuthenjwa zokungaphumeleli kweseli kubandakanya:

Isikali / isixhobo asizukuseta kwakhona okanye silungelelanise
Ukufunyanwa okungahambelaniyo okanye okungathembekanga
Ubunzima obungenakufikeleleka okanye uxinzelelo
I-orhift engaqhelekanga kwi-zero ibhalansi
Khange ifunde konke konke
Ukulayisha ingxaki:

Ukuba inkqubo yakho isebenza ngendlela engeyiyo, jonga nakuphi na ukuphathwa gadalala. Susa ezinye izizathu ezibonakalayo zokungaphumeleli kwenkqubo, iingcingo ezikhululekileyo, ufakelo okanye ufakelo okanye unxibelelwano kwi-tenen ebonisa iipaneli, njl.

Ukuba ukusilela kweselfowuni kusenzeka, uthotho lwendlela yokuchonga ingxaki kufuneka yenziwe.

Nge-DMM ethembekileyo, ekumgangatho ophezulu kwaye ubuncinci i-4.5-geji ye-4,5, uya kukwazi ukuvavanya:

I-Zero Ibhalansi
Ukunganyangeki
Ibhlorho ingqibelelo
Nje ukuba ityala lokusilela lichongiwe, iqela lakho linokuthatha isigqibo sokuba uza kuqhubeka njani.

I-Zero Ibhalansi:

Uvavanyo lwe-Zero lweZero lunokunceda ukumisela ukuba iseli yomthwalo iye yafumana nawuphi na umonakalo womzimba, njengokulayishwa, ukothuka okanye ukunxiba kwentsimbi okanye ukunxiba. Qiniseka ukuba iseli yomthwalo 'akukho mthwalo "ngaphambi kokuqala. Nje ukuba kufundwe i-lero serolise, qhagamshela intengo yokufaka umthwalo kwi-termication okanye voltage yegalelo. Linganisa i-voltage nge-millivoltmeter. Yahlula-hlula ukufundwa yigalelo okanye i-voltage voltage ukufumana ibhalansi ye-zero yeZero kwi-MV / v. Olu fundo kufuneka luhambelane nesatifikethi sokulinganisa somthwalo okanye iphepha ledatha yemveliso. Ukuba akunjalo, iseli yomthwalo imbi.

Ukunganyangeki kwe-inseza:

Ukunyangwa kokufakelwa kulinganiswa phakathi kwekhaka le-cable kunye nesekethe yeselfowuni yomthwalo. Emva kokucima iseli yomthwalo kwibhokisi yokudibanisa, qhagamshela zonke izikhokelo kunye -ukufaka kunye nemveliso. Measure the insulation resistance with a megohmmeter, measure the insulation resistance between the connected lead wire and the load cell body, then the cable shield, and finally the insulation resistance between the load cell body and the cable shield. Ukufundwa kokunyangeka kwe-insultise kufuneka ibe yi-5000 mω okanye enkulu kwi-bridge-to-to-to-cabge-to-to-to-to-cable-to-to-to-to-to-to-to-to-to-to-to-versitye. Amaxabiso asezantsi abonisa ukuvuza okubangelwe kukufuma okanye ukususwa kweekhemikhali, kwaye ukufundwa okuphezulu kakhulu luphawu oluqinisekileyo lokufutshane, hayi ukufuma.

Ibhlorho ingqibelelo:

I-Bridge ingqibelelo ijonga igalelo kunye nokungavisisiswa kwemveliso kunye nemilinganiselo ene-onmmeter kwisibini ngasinye segalelo kunye nokukhuphela kukhokelela. Sebenzisa imigaqo-nkqubo yedatha yedatha, thelekisa igalelo kunye nokuxhaphanisa okuphuma "kwimveliso engalunganga" ukuya kwigalelo elibi "kwigalelo elingalunganga". Umahluko phakathi kwamaxabiso amabini kufuneka ungabi ngaphantsi okanye alingana no-5 ω. Ukuba akunjalo, kunokubakho intambo eyaphukileyo okanye emfutshane ebangelwa yimithwalo yothusayo, inyikima, i-abrasion, okanye amaqondo obushushu agqithisileyo.

Ukunganyangeki kwempembelelo:

Iiseli zomthwalo kufuneka zidityaniswe kumthombo wamandla ozinzileyo. Emva koko usebenzisa i-Voltmeter, qhagamshela kwimveliso ikhokelela okanye iziphelo. Lumka, tyhala iiseli zomthwalo okanye iirolles zokwazisa umthwalo omncinci, ulumke ungasebenzisi imithwalo egqithisileyo. Qaphela uzinzo lokufunda kwaye ubuye kwi-zero ye-zero ye-zero ye-zero. Ukuba ukufunda kuyimpazamo, kunokubonisa unxibelelwano lombane olungaphumelelanga okanye ithutyana lombane lunokwenzakalisa i-booneline phakathi kwe-tringe gauge kunye necandelo.
