Izilinganiso kagesi yamanani non-kagesi

izilinganiso kagesi abe ukunemba okuphezulu, ukuthembeka, ubulula cheapness. Ngakho-ke, amadivaysi kagesi ziye kabanzi nesilinganiso namanani-non-kagesi.

Uhlelo kagesi ukuthi ulinganisa eliningi-non-kagesi yakhiwa izingxenye eziyisisekelo ezifana: inzwa (transducer), idivayisi Lesisemkhatsini inkomba.

izilinganiso kagesi nenani nonelectrical - lokhu elibalulekile ukuguqulwa inzwa nenani nonelectrical, bathi, ushintsho ezingeni ketshezi, isivinini, izinga lokushisa, njll, ushintsho eziguquguqukayo kagesi: impedance, voltage noma yamanje, inkomba elinganisiwe, okuyinto zikagesi elula kagesi ...

Izinsimbi zomculo ezazisetshenziswa ngoba izilinganiso kagesi zihlukaniswe ngezigaba ezimbili:

• analog ( "tseshki") - lapho umphumela nesilinganiso esikalini zedivayisi kuboniswa umcibisholo;

• digital - abayikho Converter analog-to-digital oguqula isignali okufakwayo ngenani digital futhi ubonisa it esibukweni LCD.

analog Namuhla, usule izinto zikagesi eziphezu digital esikhundleni, ungase uthi, ngokuphelele, ngoba, okokuqala:

• zingabantu kulula ukuyisebenzisa (njengoba kuqhathaniswa Analog (umcibisholo), abanakho into ezifana yokulinganisa sezingeni noma letihlungiwe yemakhono insimbi, okuyinto okumelwe ubhekane);

• zingabantu kakhulu analog esinembile.

Kufanele kuqashelwe, futhi inzuzo zinsizakuphila: izilinganiso kagesi avumela ngokuhlola yamanani non-kagesi, ngisho kanzima ukuze afinyelele izindawo noma ibanga elikhulu.

Cabangela lezi zibonelo ezimbili ezithile nokuthi bayifeze kanjani izilinganiso kagesi isebenzisa amadivayisi yokulinganisa ubukhulu non-kagesi.

Izinkuni imitha umswakama

Njengoba izinkuni - hygroscopic impahla, kanye ushintsho imingcele kwemvelo eshintsha umswakama walo - omunye izakhiwo nokhuni, okungakwazi zibaluleke kangaka lapho esetshenziswa umkhiqizo osuphelile. Ngakho-ke, izinkuni womile esimweni iyunifomu sinombono izimo zokusebenza esizayo.

Omunye izindlela sokulinganisa nokuqukethwe kwalo umswakama ukusebenzisa elektrovlagomerov. Umgomo we operation imitha umswakama ukukala nomswakama, esekelwe - sezindawo kagesi. Ngedivayisi, ungakwazi ukunquma ngokushesha ngaphandle kokubhubhisa kwezinkuni.

Umswakama amamitha kukhona ezimbili zama:

• Needle - zisekelwe yokukala ukumelana kagesi;

• capacitive (imininingwane yokuxhumana) - zisekelwe ubudlelwano phakathi njalo Kwe-dielectric Heating futhi umswakama. Lezi amamitha umswakama ibe nezinzwa angadingi ukwethulwa izinaliti eHoreshi. Ngakho-ke, phezu kobuso izinkuni engashiyanga ezisalayo ngemva nesilinganiso, okuyinto Yiqiniso, izici zabo kunenzuzo kulesi sici kusuka hydrometers inaliti.

imitha nitrate

Nitrate - lezi ezinye zamakhemikhali ukuthi kukhona eziyingozi kakhulu ngoba kungaba umthombo nokwephula zomzimba womuntu. Uma ukudla inqwaba emzimbeni womuntu, bona kungabangela ubuthi nitrate, izifo ezihlukahlukene ezingalapheki nokuphazamiseka.

Asikho isikhathi-ukudliwa futhi inqubo eqolo ye-nitrate ukuthola okwamanje ekusebenziseni kudivayisi encane ekhethekile - nitrate.

Nitratomers eklanyelwe ukukala e izithelo, imifino kanye ngokudlulisa okuqukethwe nitrate. Ngesisekelo msebenzi yokulinganisa ion okwenziwa kwisistimu electrode oqondile indlela potentiometric, imiphumela eziguqulelwa ku i kagesi isignali wakhona lokuhlushwa ion of NO3.

contact Uphenyo ekhethekile (Uphenyo) kuhlinzekelwe ngokuchaza nokukala kudivayisi indlela nitrate umkhiqizo lancing.

Nitrate - ithuluzi digital. izilinganiso zalo ukuboniswa elula umbala ukubonisa.
