Ekusetyenzisweni kwezixhobo, phantsi kweemeko eziqhelekileyo, ukusetyenziswa kweetransmitter yeyona nto ibanzi nexhaphakileyo, eyahlulwe kancinci yaba ziitransmitter zoxinzelelo kunye neetransmitter zoxinzelelo ezahlukeneyo. Iitransmitter zihlala zisetyenziselwa ukulinganisa uxinzelelo, uxinzelelo oluhlukileyo, i-vacuum, inqanaba lolwelo, njl.
Iitransmitter zahlulwe zaba ziinkqubo zeengcingo ezimbini (isignali yangoku) kunye nenkqubo yeengcingo ezintathu (isignali yevolthi). Iitransmitter ezineengcingo ezimbini (isignali yangoku) zixhaphake kakhulu; kukho ezikrelekrele nezingekrelekrele, kunye neetransmitter ezikrelekrele ngakumbi nangakumbi; ukongeza, Ngokwesicelo, kukho uhlobo olukhuselekileyo ngokwangaphakathi kunye nohlobo olungenakuqhuma; xa ukhetha uhlobo, kufuneka wenze ukhetho olufanelekileyo ngokweemfuno zakho.
1. Ukuhambelana kwesixhobo esivavanyiweyo
Xa ukhetha uhlobo, cinga ngempembelelo yesixhobo kwi-interface yoxinzelelo kunye nezinto ezibuthathaka, kungenjalo i-diaphragm yangaphandle iya konakala ngexesha elifutshane ngexesha lokusetyenziswa, nto leyo enokubangela ukubola kwizixhobo kunye nokhuseleko lomntu, ngoko ke ukukhetha izinto kubaluleke kakhulu.
2. Impembelelo yobushushu obuphakathi kunye nobushushu obuphakathi kwimveliso
Ubushushu besixhobo esilinganisiweyo kunye nobushushu obujikeleze umhlaba kufuneka kuqwalaselwe xa kukhethwa imodeli. Ukuba ubushushu buphezulu kunembuyekezo yobushushu bemveliso ngokwayo, kulula ukubangela ukuba idatha yokulinganisa imveliso ihambe. Umthumeli kufuneka akhethwe ngokwemeko yokusebenza yokwenyani ukuze kuthintelwe ubushushu obubangela umbilini obuthathaka kuxinzelelo. Umlinganiselo awuchanekanga.
3. Ukukhetha uluhlu loxinzelelo
Umlinganiselo woxinzelelo wesixhobo sokuhambisa uxinzelelo kufuneka uhambelane nomlinganiselo woxinzelelo wesixhobo xa sisebenza.
4. Ukukhetha ujongano loxinzelelo
Kwinkqubo yokukhetha, ubungakanani bomsonto obufanelekileyo kufuneka bukhethwe ngokwesayizi yesithuba soxinzelelo sezixhobo ezisetyenzisiweyo;
5. Ukukhetha ujongano lombane
Xa ukhetha imodeli, kuyimfuneko ukuqinisekisa ukusetyenziswa kweendlela zokufumana isignali kunye neemeko zocingo kwindawo. Isignali yesinzwa kufuneka iqhagamshelwe kwi-interface yokufumana umsebenzisi; khetha i-pressure sensor ene-interface yombane kunye nendlela yesignali efanelekileyo.
6. Ukukhetha uhlobo loxinzelelo
Isixhobo esilinganisa uxinzelelo olupheleleyo sibizwa ngokuba yi-absolute pressure gauge. Kwii-industrial industrial pressure gauge, uxinzelelo lwe-gauge luyalinganiswa, oko kukuthi, umahluko woxinzelelo phakathi koxinzelelo olupheleleyo kunye noxinzelelo lomoya. Xa uxinzelelo olupheleleyo lukhulu kunoxinzelelo lomoya, uxinzelelo lwe-gauge olulinganisiweyo lulungile, olubizwa ngokuba yi-positive gauge pressure; xa uxinzelelo olupheleleyo lungaphantsi koxinzelelo lomoya, uxinzelelo lwe-gauge olulinganisiweyo lulungile, olubizwa ngokuba yi-negative gauge pressure, oko kukuthi, i-degree of vacuum. Isixhobo esilinganisa i-degree of vacuum sibizwa ngokuba yi-vacuum gauge.
