Iitransmitter zoxinzelelo lweoyile ezikwi-inlinezizixhobo ezibalulekileyo ekulinganiseni uxinzelelo lweoyile ngaphakathi kwipayipi okanye kwinkqubo, zibonelela ngokujonga nokulawula uxinzelelo ngexesha langempela. Xa kuthelekiswa neetransmitter zoxinzelelo eziqhelekileyo, iimodeli ezikwimigca eyenzelwe ukuhlanganiswa okungenamthungo kwindlela yokuhamba ngokudibanisa okunemisonto okanye okujijekileyo, kuba zilungele ioyile negesi, iimoto, iinkqubo zehydraulic kunye noomatshini bemizi-mveliso.
Fumana iimfuno ezithile zesicelo ngaphambi kokuba ukhethe ii-inline oil pressure transmitters. Ukufundwa koxinzelelo okulinganisiweyo kuguqulwa kube ziimpawu zombane kwaye kuhanjiswe kwinkqubo yolawulo olukrelekrele ukuze kuhlalutywe ngakumbi kwaye kulawulwe.
Izinto Ezibalulekileyo Ezifuna Ukuqwalaselwa Ngononophelo
Uluhlu loxinzelelo, ukuhamba kunye nokuqina, ubuchwepheshe obahlukeneyo bokuva, izinto ezihambelanayo kunye nesignali yokuphuma kufuneka kuthathelwe ingqalelo ukuze kujongwe ngokuchanekileyo nangokuthembekileyo. Kwangaxeshanye, iimfuno zokusingqongileyo kunye nokhuseleko kufuneka zixatyiswe ngokuthobela imithetho kwiindawo ekujoliswe kuzo.
Iimfuneko zeSicelo seXabiso
Uxinzelelo lweoyile oluncinci noluphezulu kwimibhobho lugqiba ukubauluhlu lwee-transmitters zoxinzeleloigubungela la maxabiso ukuthintela umonakalo onokubakho okanye ukufundwa okungachanekanga.
Iintlobo zokulinganisa uxinzelelozahlulwe ngoxinzelelo lwegeyiji, uxinzelelo olupheleleyo kunye noxinzelelo lomahluko, zinxulumene noxinzelelo lomoya, i-vacuum okanye umahluko phakathi kwamanqaku amabini ahambelanayo.
Ii-diaphragms zokuhlamba ziyafunekaikrakra okanye ixakekeukuhamba kwamanzi ngenxa yokoyika ukuvaleka okanye iimpazamo zokulinganisa.
Iiteknoloji zokuva iiTransmitters zoxinzelelo
Ii-capacitive transmitterszifanelekile kwiinjongo ezibanzi, apho kufuneka khona izisombululo zokudlulisa uxinzelelo ezingabizi kakhulu nezichanekileyo ngokuphakathi;
Iitransmitter zesilicon ezisasazekileyozisebenza kwiinkqubo ze-hydraulic okanye ze-oyile negesi ukuze zichaneke kakhulu kwaye zizinzile kumanqanaba oxinzelelo olubanzi;
Izixhobo ezihambelanayo
Khetha iSignali yokuPhuma echanekileyo
Imveliso yomthumeli kufuneka idibane nenkqubo yakho yokulawula okanye yokubeka esweni:
- 4-20 mA: Umgangatho wokusetyenziswa kwemizi-mveliso, othembekileyo ekudluliseleni isignali kumgama omde.
- 0-10 V: Ifanelekile kwiinkqubo ezisekelwe kumbane, ezisetyenziswa rhoqo kwiisetingi zeemoto okanye ezincinci.
- Iziphumo zeDijithali (umz., iHART, iModbus): Ikhethwa kwiinkqubo ezikrelekrele ezifuna ukuxilongwa okanye uqwalaselo olukude.
Qinisekisa ukuba isignali yokuphuma ihambelana neemfuno zenkqubo yakho ukuqinisekisa ukuhlanganiswa okungenamthungo.
Vavanya iiMfuno zeNdalo kunye noKhuseleko
Iitransmitter ezikwi-inline zihlala zichatshazelwa ziimeko ezinzima:
- Iindawo Eziyingozi: Kwizicelo zeoyile negesi (umz., imibhobho, iindawo zokucoca), khetha izixhobo zokuhambisa ezikhuselekileyo okanye ezikhuselekileyo ngokwangaphakathi eziqinisekiswe yimigangatho efana ne-ATEX, FM, okanye i-CSA ukuthintela iingozi zokutsha.
- Ukhuseleko Lokungena (Uvavanyo lwe-IP/NEMA): Kwiindawo ezingaphandle okanye ezimanzi, khetha i-transmitter ene-IP rating ephezulu (umz., IP67 okanye IP68) ukukhusela uthuli, amanzi, okanye ukungena kweoyile.
- Uluhlu lobushushu: Qinisekisa ukuba i-transmitter isebenza ngaphakathi kwemida yobushushu benkqubo yakho. Ii-inline transmitters kwizicelo zobushushu obuphezulu (umz., ukujonga ioyile yenjini) zifuna ukunyamezela ubushushu obuqinileyo.
Khetha uQhagamshelo lweNkqubo oluchanekileyo
Iitransmitter ezikwimigca kufuneka ziqhagamshele ngokukhuselekileyo kumbhobho:
- Uqhagamshelo olunemisonto: Iindlela eziqhelekileyo ezifana ne-1/4” NPT, G1/2, okanye i-M20 threads zifanelekile kwiindlela ezininzi zokusetyenziswa ngaphakathi. Qinisekisa ukuba utywina ngokufanelekileyo (umz., ii-O-rings okanye iteyiphu ye-PTFE) ukuthintela ukuvuza.
- Uqhagamshelo oluHlangeneyo: Isetyenziswa kwimibhobho enoxinzelelo oluphezulu okanye olukhulu ukuze kuthotywe uxinzelelo oluphantsi kwaye kufakwe ngokukhuselekileyo.
- Ukuhambelana kobungakanani bepayipi: Qinisekisa ukuba uqhagamshelo lomthumeli luhambelana nobubanzi bombhobho wakho ukuze kuthintelwe imiqathango yokuhamba okanye iingxaki zokufakelwa.
Khetha uhlobo loqhagamshelo oluqinisekisa ukuba ukufakelwa okuzinzileyo nokungavuziyo ngaphandle kokuphazamisa ukuhamba kwamanzi.
Ibhalansi yeendleko kunye nokusebenza
Nangona izixhobo ezikumgangatho ophezulu ezifana ne-tantalum okanye iteknoloji eziphambili ziphucula ukuqina kunye nokuchaneka, zisenokungabi yimfuneko kwizicelo ezingabizi kakhulu. Iitransmitter ezisekelwe kwi-SS316L ezineteknoloji ye-capacitive okanye ye-piezoresistive zihlala zibonelela ngebhalansi engabizi kakhulu. Cinga ngeendleko zobomi bonke, kubandakanya ukugcinwa, ukulinganiswa, kunye nexesha lokungasebenzi, xa uvavanya iindlela. Itransmitter ethembekileyo inciphisa iindleko zexesha elide.
