Ekusetyenzisweni kwe-instrumentation, phantsi kweemeko eziqhelekileyo, ukusetyenziswa kwee-transmitter yeyona nto ibanzi kwaye ixhaphake, eyahlulahlulwe ngokulinganayo ibe yi-pressure transmitters kunye ne-different pressure transmitters.Iitransmitha zihlala zisetyenziselwa ukulinganisa uxinzelelo, uxinzelelo lokwahlukana, i-vacuum, inqanaba lolwelo, njl.
Abadlulisi bahlulwe kwiinkqubo ezimbini zocingo (umqondiso wangoku) kunye nenkqubo yocingo lwesithathu (umqondiso we-voltage).Iintambo ezimbini (uphawu lwangoku) zixhaphake ngokukodwa;kukho abakrelekrele nabangengabo, nabasasaza abakrelekrele ngakumbi nangakumbi;ukongeza , Ngokwesicelo, kukho uhlobo olukhuselekileyo lwangaphakathi kunye nohlobo lobungqina bokudubula;xa ukhetha uhlobo, kuya kufuneka wenze ukhetho oluhambelanayo ngokweemfuno zakho.
1. Ukuhambelana kwendlela evavanyiweyo
Xa ukhetha uhlobo, qwalasela impembelelo ye-medium kwi-interface yoxinzelelo kunye namacandelo abuthathaka, ngaphandle koko i-diaphragm yangaphandle iya kutshatyalaliswa ngexesha elifutshane ngexesha lokusetyenziswa, elinokubangela ukubola kwisixhobo kunye nokhuseleko lomntu, ngoko ke ukhetho lwezinto eziphathekayo ibaluleke kakhulu .
2. Impembelelo yobushushu obuphakathi kunye nobushushu be-ambient kwimveliso
Ubushushu bomlinganiselo ophakathi kunye nobushushu be-ambient kufuneka buthathelwe ingqalelo xa ukhetha imodeli.Ukuba iqondo lokushisa liphezulu kunembuyekezo yeqondo lokushisa kwemveliso ngokwayo, kulula ukubangela ukuba idatha yokulinganisa imveliso iqhube.I-transmitter kufuneka ikhethwe ngokwendawo yokusebenza yokwenyani ukuphepha ubushushu obubangela i-core-sensitive core.Umlinganiselo awuchanekanga.
3. Ukukhethwa koluhlu loxinzelelo
Iqondo loxinzelelo lwe-pressure transmitter kufuneka lihambelane noxinzelelo lwesixhobo xa sisebenza.
4. ukhetho lwe-interface yoxinzelelo
Kwinkqubo yokukhetha, ubungakanani bomsonto obufanelekileyo kufuneka bukhethwe ngokobungakanani bezibuko loxinzelelo lwezixhobo ezisetyenzisiweyo;
5. Ukukhethwa kwe-interface yombane
Xa ukhetha imodeli, kuyimfuneko ukuqinisekisa ukusetyenziswa kweendlela zokufumana umqondiso kunye neemeko ze-wiring kwisayithi.Umqondiso woluvo kufuneka uqhagamshelwe kwi-interface yokufumana umsebenzisi;khetha inzwa yoxinzelelo ngombane ochanekileyo kunye nendlela yomqondiso.
6. Ukukhetha uhlobo loxinzelelo
Isixhobo esilinganisa uxinzelelo olupheleleyo sibizwa ngokuba yigeyiji yoxinzelelo olupheleleyo.Kwiigeyiji eziqhelekileyo zoxinzelelo lwamashishini, uxinzelelo lwegeyiji luyalinganiswa, oko kukuthi, umahluko woxinzelelo phakathi koxinzelelo olupheleleyo kunye noxinzelelo lwe-atmospheric.Xa uxinzelelo olupheleleyo lukhulu kunoxinzelelo lwe-atmospheric, umlinganiselo we-gauge olinganisiweyo ulungile, obizwa ngokuba yi-positive gauge pressure;xa uxinzelelo olupheleleyo lungaphantsi koxinzelelo lwe-atmospheric, i-gauge elinganisiweyo yoxinzelelo i-negative, ebizwa ngokuba yi-negative gauge pressure, oko kukuthi, iqondo le-vacuum.Isixhobo esilinganisa iqondo levacuum sibizwa ngokuba yivacuum gauge.
