I-XDB702 PT100 Temperature Sensor: Ukuqonda Izindlela Ezihlukile Zezintambo

Izinzwa zokushisa ze-PT100 zisetshenziswa kabanzi ezinhlelweni ezishintshayo nezilawulayo zezimboni ukukala izinga lokushisa ngokunembile nangokwethembeka.Inzwa yokushisa ye-XDB702 PT100 iyidivayisi esebenza kahle kakhulu eklanyelwe ngokuqondile ukuguqula amasiginali wokumelana neplatinamu ye-PT100 ibe amasignali okukhiphayo angu-4-20mA.Kulesi sihloko, sizohlola izindlela ezihlukene zokufaka izintambo ezisetshenziselwa izinzwa zokushisa ze-PT100.

Izinzwa zokushisa ze-PT100 zivame ukufakwa ngokuqondile kumabhokisi okuhlanganisa ukumelana ne-platinamu ye-PT100, ahlanganisa izinhlobo ezahlukene zokuphikiswa kwe-platinum ezakha inzwa yokushisa ehlanganisiwe ye-thermoresistance.Lezi zinzwa ziguqula amasiginali we-PT100 weplatinamu abe amasiginali okukhiphayo angu-4-20mA.Kodwa-ke, lapho izinzwa zokushisa ze-PT100 zisetshenziselwa ukudlulisa okukude kwezimpawu zokumelana ne-platinamu ye-PT100, zingase zibe ngaphansi kokuphazanyiswa okunamandla kwesayithi noma zidinge ukuxhunywa kusistimu ye-DCS.

Inzwa yokushisa ye-XDB702 PT100 iklanywe ngesakhiwo sebhodi lesifunda esinezendlalelo ezimbili esiyingqayizivele, enesendlalelo esingezansi esinikezelwe ukulungiswa kwesignali kanye nongqimba olungaphezulu olusetshenziselwa ukunquma uhlobo lwenzwa nobubanzi bokulinganisa.

Izici Ezibalulekile Zenzwa Yezinga Lokushisa ye-XDB702 PT100

Ukukhishwa komugqa kwe-2-wire 4-20mA isignali yamanje evamile, enesakhiwo semodular.

Inzwa yezinga lokushisa ye-XDB702 PT100 isebenzisa izingxenye ezingenisiwe, iqinisekisa ukusebenza okuthembekile kanye nokukhukhuleka okuncane kwezinga lokushisa.

Idivayisi ifaka isekethe yokuvikela ukuhlehla kwe-polarity, evikela isiyingi lapho okukhiphayo kubuyiselwa emuva (lapho okwamanje kunguziro).

Umkhiqizo futhi unokuvikela kwe-RFI/EMI, okusiza ukuthuthukisa ukuqina kokulinganisa.

Ububanzi benzwa yokushisa ye-XDB702 PT100 abukwazi ukushintshwa ngokuthanda kwakhe, futhi umenzi kuphela ongaqinisekisa imininingwane yokukhiqiza.

Ukuhambisana kwe-electromagnetic kwenzwa yokushisa ye-PT100 kuhambisana namazinga e-European Electrical Committee (EC) BSEN50081-1 kanye ne-BSEN50082-1.

Izindlela Zokufaka Izintambo Zezinzwa Zezinga Lokushisa ze-PT100

Inzwa yezinga lokushisa ye-PT100 ivamise ukuxhunywa kutheminali yesikulufu phezulu kwekesi yayo.Ukuze kuhlangatshezwane nezidingo zesitifiketi se-CE, ubude bezintambo zokufaka isignali akumele budlule amamitha angu-3, ​​futhi izintambo eziphumayo kufanele zibe ikhebula elivikelekile, ngocingo lwesihlangu luxhunywe emhlabathini ohlangothini olulodwa kuphela.

Imbobo emaphakathi yenzwa isetshenziselwa izintambo zesignali yokumelana neplatinamu ye-PT100, futhi intambo yesiginali yokumelana neplatinamu ye-PT100 ijikijelwa ngokuqondile ekugcineni kokufaka kwenzwa kusetshenziswa isikulufu.Amatheminali aklanyelwe isikulufu angasetshenziselwa izintambo zangaphakathi noma zangaphandle.

Enye indlela yokuxhuma inzwa yokushisa ye-PT100 imi kanje:

Inzwa yokumelana neplatinamu ye-PT100 inezintambo ezintathu: A, B, no-C (noma ezimnyama, ezibomvu, neziphuzi).U-A no-B noma u-C banenani lokumelana elingama-ohm angu-110 ekamelweni lokushisa, kuyilapho inani lokumelana phakathi kuka-B no-C licishe libe ngu-0 ohms, u-B no-C axhumeke ngaphakathi.Isiphetho esigxilile sensimbi exhunywe kunzwa inamatheminali amathathu: A ixhunywe ekugcineni okugxilile kwethuluzi, kuyilapho u-B no-C axhunywe kwezinye iziphetho ezimbili ezigxilile zethuluzi.I-B no-C ingashintshwa, kodwa kufanele ixhunywe.Uma kusetshenziswa intambo ende phakathi, imininingwane nobude bezintambo ezintathu kumele kufane.

I-PT100 ingaxhunywa kusetshenziswa izindlela ze-2-wire, 3-wire, noma 4-wire, kuye ngezinsimbi ezisetshenzisiwe.Izisetshenziswa ezijwayelekile zokubonisa zihlinzeka ngoxhumo lwezintambo ezingu-3, ​​ngomkhawulo owodwa wenzwa ye-PT100 exhunywe ocingweni olulodwa kanti omunye uxhumeke ezintanjeni ezimbili ezixhunywe kuthuluzi.Ukumelana nocingo lwangaphakathi lwensimbi kulinganisaniswa nebhuloho.Ama-PLC ngokuvamile asebenzisa ukuxhumana kwezintambo ezingu-4, nezintambo ezimbili ezixhunywe ekugcineni ngakunye kwenzwa ye-PT100 kanye nezintambo ezimbili ezixhunywe emthonjeni wamanje ophumayo oqhubekayo we-PLC.I-PLC ikala i-voltage kwezinye izintambo ezimbili ukulinganisa ukumelana kwezintambo.Uxhumo lwezintambo ezine yilona olunembe kakhulu, kuyilapho uxhumo lwezintambo ezintathu lwamukelekile, futhi uxhumo lwezintambo ezimbili lunembe kancane.Indlela eqondile esetshenziswayo incike ekunembeni okudingekile kanye nezindleko.
