I-XDB702 PT100 i-Temperature Sensor: Ukuqonda iindlela ezahlukeneyo zokuFinga

Iinzwa ze-PT100 zeqondo lokushisa zisetyenziswa ngokubanzi kwi-industrial automation kunye neenkqubo zokulawula ukulinganisa ukushisa ngokuchanekileyo nangokuthembeka.I-sensor ye-XDB702 PT100 yeqondo lokushisa yisixhobo esiphezulu esilungiselelwe ngokukodwa ukuguqula iimpawu ze-PT100 zeplatinam zokumelana neempawu ze-4-20mA zemveliso.Kweli nqaku, siza kuphonononga iindlela ezahlukeneyo zocingo ezisetyenziselwa i-PT100 sensors zobushushu.

Iinzwa ze-PT100 zeqondo lokushisa zivame ukufakwa ngokuthe ngqo kwiibhokisi ze-PT100 zeplatinam zokuxhathisa, ezibandakanya iintlobo ezahlukeneyo zokuchasana kwe-platinum ezenza i-thermoresistance edibeneyo yokushisa inzwa yokushisa.Ezi zinzwa ziguqula iimpawu ze-PT100 zeplatinam kwiimpawu ze-4-20mA zemveliso.Nangona kunjalo, xa i-PT100 izinzwa zobushushu zisetyenziselwa ukuhanjiswa okude kwe-PT100 yeempawu zokumelana neplatinam, zinokuba phantsi kokuphazamiseka okunamandla kwisiza okanye zifuna uqhagamshelo kwinkqubo ye-DCS.

I-sensor ye-XDB702 PT100 yeqondo lokushisa yenzelwe kunye nesakhiwo sebhodi yesiphaluka esisodwa esiphindwe kabini, kunye nomgangatho ophantsi onikezelwe ukulungiswa komqondiso kunye nomgangatho ophezulu osetyenziselwa ukumisela uhlobo lwenzwa kunye noluhlu lokulinganisa.

Iimpawu eziphambili ze-XDB702 PT100 yoVavanyo lobushushu

Imveliso yomgca we-2-wire 4-20mA isignali eqhelekileyo yangoku, kunye nesakhiwo semodyuli.

I-sensor ye-XDB702 PT100 yeqondo lokushisa isebenzisa amacandelo angaphandle, iqinisekisa ukusebenza okuthembekileyo kunye nokushisa okuncinci.

Isixhobo sibonisa i-polarity reversal protection circuit, ekhusela isiphaluka xa isiphumo siguqulwa (apho imeko yangoku i-zero).

Imveliso nayo inokhuseleko lwe-RFI / EMI, olunceda ukuphucula ukuzinza komlinganiselo.

Uluhlu lwe-XDB702 PT100 inzwa yeqondo lokushisa ayinakuguqulwa ngokuthanda, kwaye kuphela umenzi onokuqinisekisa iinkcukacha zemveliso.

Ukuhambelana kwe-electromagnetic ye-PT100 yeqondo lokushisa ihambelana neKomiti yoMbane yaseYurophu (EC) BSEN50081-1 kunye nemigangatho ye-BSEN50082-1.

Iindlela zocingo ze-PT100 zoVavanyo lobushushu

Inzwa yobushushu be-PT100 ngokuqhelekileyo iqhagamshelwe kwi-screw terminal phezu kwe-casing yayo.Ukuhlangabezana neemfuno zesatifikethi se-CE, ubude be-wiring yokufakelwa kwesignali akufanele budlule i-3 yeemitha, kwaye i-wiring ye-output kufuneka ikhuseleke ikhebula, kunye nocingo lwekhaka oluqhagamshelwe phantsi kwelinye icala kuphela.

Umngxuma ophakathi we-sensor isetyenziselwa i-PT100 i-platinamu yokumelana nocingo lwe-wire, kunye ne-PT100 iplatinam yokumelana nocingo lwesignali ifakwe ngokuthe ngqo kwi-input end of the sensor usebenzisa i-screw.Iitheminali ze-screw eziyilelwe zingasetyenziselwa iingcingo zangaphakathi okanye zangaphandle.

Enye indlela yokudibanisa inzwa yobushushu be-PT100 yile ilandelayo:

I-sensor ye-PT100 yokumelana ne-platinum ineentambo ezintathu: A, B, kunye no-C (okanye umnyama, obomvu, kunye nophuzi).I-A kunye ne-B okanye i-C inexabiso lokumelana ne-110 ohms kwiqondo lokushisa, ngelixa ixabiso lokumelana phakathi kwe-B kunye ne-C lijikeleze i-0 ohms, kunye ne-B kunye ne-C edibeneyo ngaphakathi.Isiphelo esisisigxina sesixhobo esidityaniswe kwi-sensor sinee-terminals ezintathu: I-A ixhunywe kwisiphelo esisisigxina sesixhobo, ngelixa i-B kunye ne-C ixhunywe kwezinye iziphelo ezimbini ezisisigxina zesixhobo.I-B kunye no-C inokutshintshwa, kodwa kufuneka idibaniswe.Ukuba kusetyenziswe ucingo olude phakathi, iinkcukacha kunye nobude beentambo ezintathu kufuneka zifane.

I-PT100 inokudibaniswa ngokusebenzisa i-2-wire, i-3-wire, okanye iindlela ze-4-wire, kuxhomekeke kwizixhobo ezisetyenzisiweyo.Izixhobo zokubonisa eziqhelekileyo zibonelela nge-3-wire connection, kunye nesinye isiphelo se-PT100 sensor exhunywe kwintambo enye kunye nesinye isiphelo esixhunyiwe kwiintambo ezimbini ezidibaniswe nesixhobo.Ukuxhathisa ucingo lwangaphakathi lwesixhobo kulungelelaniswa yibhuloho.Ii-PLC zihlala zisebenzisa i-4-wire connections, kunye neengcingo ezimbini ezidibeneyo ekupheleni kwe-PT100 sensor kunye neengcingo ezimbini ezixhunyiwe kwi-output eqhubekayo yomthombo wangoku we-PLC.I-PLC ilinganisa amandla ombane kwezinye iingcingo ezimbini ukulinganisa ukuxhathisa kwecingo.Iintambo ezine zezona zichanekileyo, ngelixa ukudibanisa kweentambo ezintathu kwamkelekile, kwaye ukuqhagamshelwa kweengcingo ezimbini kuncinci.Indlela ethile esetyenziswayo ixhomekeke ekuchanekeni okufunekayo kunye neendleko.
