Ukulinganiswa kwezinga loketshezi kuyisici esibalulekile ezimbonini ezahlukahlukene njengokukhiqiza, amakhemikhali, uwoyela negesi. Ukulinganiswa kwezinga okunembile kubalulekile ekulawulweni kwenqubo, ukuphathwa kwempahla, kanye nokuphepha kwemvelo. Enye yezindlela ezisebenzayo kakhulu zokulinganisa izinga loketshezi ukusebenzisa inzwa yokucindezela noma i-transmitter yokucindezela.
I-pressure transmitter ingasetshenziswa ukusungula izinga loketshezi emfuleni, ethangini, emthonjeni, noma komunye umzimba woketshezi. Isebenza ngesimiso sokucindezela kwe-hydrostatic, okuyingcindezi ekhishwa uketshezi olumile ngenxa yamandla adonsela phansi. Uma inzwa yokucindezela ifakwa phansi kwethangi noma esinye isitsha esiqukethe uketshezi, ilinganisa ingcindezi ekhishwa uketshezi olungaphezu kwalo. Lokhu kufundwa kwengcindezi kungasetshenziswa ukunquma ngokunembile izinga loketshezi.
Kunezinhlobo ezahlukene zezinzwa zokucindezela kanye nama-transmitter angasetshenziswa ekulinganisweni kwezinga loketshezi. Lokhu kufaka phakathiizinzwa zokucindezela ezicwiliswa emanzini, ezenzelwe ukucwiliswa oketshezini, kanyeama-transmitter okucindezela angacwiliswanga emanzini, ezifakwa ngaphandle ethangini noma esitsheni. Zombili izinhlobo zezinzwa zisebenza ngokuguqula ingcindezi ye-hydrostatic yoketshezi ibe isignali kagesi engalinganiswa futhi isetshenziswe ekulinganisweni kwezinga.
Ukufakwa kwenzwa yokucindezela ukuze kulinganiswe izinga loketshezi kuyinqubo elula. Inzwa ivame ukufakwa phansi kwethangi noma isitsha, lapho ingalinganisa khona ngokunembile ingcindezi ye-hydrostatic ekhishwa uketshezi. Isignali kagesi evela kunzwa ithunyelwa kumlawuli noma iyunithi yokubonisa, lapho iguqulwa ibe yisilinganiso sezinga. Lokhu kulinganisa kungaboniswa ngamayunithi ahlukahlukene njengamasentimitha, izinyawo, amamitha, noma iphesenti lomthamo wethangi, kuye ngezidingo zesicelo.
Enye yezinzuzo ezibalulekile zokusebenzisa inzwa yokucindezela ukulinganisa izinga loketshezi ukunemba kwayo nokuthembeka kwayo. Ngokungafani nezinye izindlela zokulinganisa izinga, izinzwa zokucindezela azithintwa yizici ezifana nokushisa, ukuthamba, noma igwebu, futhi zinganikeza ukufundwa kwezinga okuhambisanayo nokunembile. Lokhu kuzenza zifaneleke ezinhlobonhlobo eziningi zoketshezi kanye nezinhlobo zamathangi, kufaka phakathi lezo eziqukethe izinto ezibolayo noma eziyingozi.
Ukusetshenziswa kwezinzwa zokucindezela kanye nama-transmitter ekulinganisweni kwezinga loketshezi kuyindlela eqinisekisiwe nephumelelayo yezinhlelo zokusebenza ezahlukahlukene zezimboni. I-Shanghai Wangyuan Instruments of Measurement Co., Ltd. iyinkampani yaseShayina esezingeni eliphezulu lebhizinisi egxile kubuchwepheshe bokuzenzakalela kwenqubo kanye nemikhiqizo iminyaka engaphezu kwengu-20. Singahlinzeka ngama-transmitter okucindezela afakwe ngaphansi komhlaba kanye nangaphandle angabizi kakhulu anomklamo wokulinganisa izinga. Zizwe ukhululekile ukuxhumana nathi ukuthola ulwazi olwengeziwe.
