Ukulinganisa uxinzelelo kunye nokubeka iliso yinxalenye ebalulekileyo yeenkqubo zanamhlanje zoshishino. Uxinzelelo oluza kulinganiswa lunokuchazwa njengeendidi ezahlukeneyo ngokusekelwe kwisalathiso sokulinganisa. Nangona ukulinganisa uxinzelelo kunokwanela kwiintlobo ezininzi zemveliso, ngamanye amaxesha sebenzisa isixhobo esibonisa uxinzelelo olupheleleyo.
Uxinzelelo olupheleleyo kunye noxinzelelo lweGauge
Umoya wehlabathi unobunzima kwaye udala uxinzelelo ngokwawo. Ubungakanani boxinzelelo lomoya bukwabizwa ngokuba luxinzelelo lwe-ambient, oluyahluka malunga ne-101.325kPa (umoya oqhelekileyo) ngokwendawo ephakamileyo kunye neemeko zemozulu. Umahluko ophambili woxinzelelo olupheleleyo kunye noxinzelelo lwe-gauge uxhomekeke ekubeni uxinzelelo lomoya lufakiwe na. Indawo yokubhekisa yoxinzelelo lwe-gauge luxinzelelo lomoya ngelixa uxinzelelo olupheleleyo luyindawo ye-vacuum apho uxinzelelo lomoya lungekho kwaphela. Ke ngoko, ukufundwa koxinzelelo olupheleleyo kubonisa isixa soxinzelelo lomoya kunye noxinzelelo lwe-gauge.
Uxinzelelo ludla ngokulinganiswa ngokulinganisa ukuguquka kwento yokubona, apho elinye icala lento livezwa kwireferensi kwaye elinye icala lidibana nenkqubo ye-process medium. Kwi-gauge pressure sensor, icala le-diaphragm elingadibananga ne-medium livulelwa kuxinzelelo oluhambelanayo, nto leyo enika ukufundwa koxinzelelo lwe-gauge oluyiyo umahluko woxinzelelo phakathi kwenkqubo kunye noxinzelelo lomoya. Nge-absolute pressure sensor, i-diaphragm ivezwa kwigumbi le-absolute vacuum elivalwe ngokusisigxina. Ekubeni i-vacuum evaliweyo isetyenziswa njengendawo yokubhekisa, ukuguquguquka kwe-diaphragm akuchaphazeleki ngumoya.
Ekubeni izakhiwo zoshishino zihlala zinesimo esifanayo sokuphakama kwaye ukusetyenziswa kwazo koxinzelelo akuchaphazeleki lutshintsho kuxinzelelo lomoya, umlinganiselo woxinzelelo oluqhelekileyo uchanekile ngokwaneleyo kwiinkqubo ezininzi. Nangona kunjalo, iimeko ezikhethekileyo zifuna uxinzelelo olupheleleyo, oluzimeleyo kutshintsho kuxinzelelo lomoya. Iitransmitter zoxinzelelo olupheleleyo zihlala zibonakala kwicandelo lokucubungula iikhemikhali, uhambo ngenqwelomoya, i-HVAC, ngenxa yezizathu ezilandelayo eziqhelekileyo:
- ✦ Le nkqubo ifuna ukugcina i-vacuum okanye imeko yoxinzelelo oluphantsi kakhulu, nto leyo edinga umlinganiselo woxinzelelo olupheleleyo ukuze kugcinwe ixabiso elichanekileyo.
- ✦ Le nkqubo ixhomekeke ekukhupheni igesi okanye ekukhupheni igesi kwaye kufuneka yazi amandla apheleleyo aseleyo kwigumbi ukuze kuqinisekiswe ukuba le nkqubo igqityiwe nini.
- ✦ Isitya sisebenza phantsi kwe-vacuum ukuze kuncitshiswe iqondo lokubila eliphakathi kwaye ulawulo oluchanekileyo loxinzelelo olupheleleyo lubalulekile.
- ✦ Ngexesha lovavanyo lwenjini, uxinzelelo olukwi-intake manifold ludla ngokuba ngaphantsi koxinzelelo lomoya kwaye luyimfuneko ekubaleni ubunzima bomoya.
Shanghai Wangyuanngumvelisi onamava kunye nomthengisi wezixhobo zokulinganisa kangangeminyaka engaphezu kwama-20. I-Wangyuan inikezela uluhlu olubanzi lwezixhobo zokulinganisa.abathumeli boxinzelelongezisombululo zokulinganisa kuquka uxinzelelo olupheleleyo, oluyi-gauge kunye nolwe-differential. Ukuba unemibuzo malunga nokukhetha ii-absolute pressure transmitters, nceda uzive ukhululekile ukunxibelelana nathi.
