I-Temperature Transmitter

Inzwa ye-thermistor ye-Rosemont 214C isebenzisa iyunithi ye-Pt-100 noma i-dual-element thermistor (RTD), ehlanganisa izinga lokushisa ukusuka ku- -196 kuya ku-600 ° C (-321 kuya ku-1112 ° F). Le nzwa iyisixazululo esikhethekile esamukela ifilimu elincanyana kanye nomklamo wamanxeba, okuthuthukisa ukuguquguquka kwesicelo. Le nzwa inezinketho eziningi zokulinganisa, okuhlanganisa ukunemba kwezinzwa zeBanga A noma zeBanga B, futhi ihlinzeka ngokuqhubekayo kwe-Calendar-Van Dusen yesithumeli - ukufanisa inzwa ukuze kufezwe ukunemba okuphezulu.

Isekela okokufaka kwe-thermocouple, ukumelana nokushisa, i-DC voltage noma amasiginali wokumelana.
Iguqulelwe ku-4-20 mA DC isignali noma okukhiphayo kwesiginali ye-fieldbus.
Ihlukaniswe yaba uhlobo lokuxhumana lwe-HART kanye nohlobo lwe-FOUNDATIONTM yebhasi lokuxhumana.
Uhlobo lokuxhumana lwe-HART luthobela izinga lokuphepha le-SIL2.

I-YTA610 inikeza ukunemba okuphezulu, ukuzinza, nokuthembeka. Isakhiwo sezindlu samukela isakhiwo esinokwethenjelwa esinamagumbi amabili. Okokufaka kwenzwa kungaba ukukhetha okokufaka okukodwa noma okukabili. Lokhu okokufaka kungamukela i-RTD, i-thermocouple, i-ohm, noma i-DC millivolt. Iguqula okokufaka kwenzwa kube isignali ye-analog ye-4 kuya ku-20 mA DC noma isignali yedijithali ye-Fieldbus. I-HART 7 Protocol noma inguqulo ye-FOUNDATION™ Fieldbus ITK 6 iyatholakala. Okokufaka okukabili kungamukela isibalo sezinzwa ezimbili zevelu ehlukile noma emaphakathi kanye nomsebenzi wokusekela inzwa. Imisebenzi eyisipele yenzwa yokushintsha ngokuzenzakalelayo ukusuka kokuyinhloko ukuya kukhophi yasenqolobaneni ekuhlulekeni kwenzwa. Ngokwamukela ukushintshwa kwepharamitha yendawo ku-Indicator, kuba lula ukwenza umsebenzi wokusetha endaweni.

I-YTA710 ifaka ukunemba okuphezulu, ukuzinza okuphezulu nokuthembeka okuphezulu. Isakhiwo segobolondo sithatha isakhiwo esinokwethenjelwa esinamagumbi amabili. Okokufaka kwenzwa kungakhethwa njengokufaka okukodwa noma okokufaka okukabili. Ingamukela amasiginali okokufaka ahlukahlukene njenge-RTD, i-thermocouple, ukumelana, ne-DC voltage. Iguqula okokufaka kwenzwa kube isignali ye-analog ye-4-20 mA DC noma isignali yedijithali ye-fieldbus. Iphrothokholi ye-HART 7, iphrothokholi ye-BRAIN noma inguqulo ye-FOUNDATION™ Fieldbus ITK 6 inikeziwe. Okokufaka okukabili kungamukela ukubala okuhlukile noma okumaphakathi kwezinzwa ezimbili futhi kubone nomsebenzi wokusekela inzwa. Umsebenzi wokulondoloza inzwa usetshenziselwa ukushintsha ngokuzenzakalelayo kusuka kudivayisi eyinhloko kuya kudivayisi eyisipele lapho inzwa ingasebenzi kahle. Amapharamitha akusayithi angasethwa ngokusebenzisa inkinobho yepharamitha esendaweni kusibonisi.

Isidlulisi sezinga lokushisa se-Rosemount 248, njengesixazululo esijwayelekile semboni, singanikeza ukusebenza okungaguquki nokuthembekile endaweni yenqubo. Idizayini yesitimela ehlangene ye-DIN kulula ukuyifaka futhi isebenza kabanzi, ihlangabezana nezidingo ezijwayelekile zokulinganisa izinga lokushisa kwephuzu elilodwa.

Isidlulisi sezinga lokushisa se-Rosemount 3144P sikunikeza izilinganiso zokushisa ezihamba phambili embonini ngokunemba, ukuzinza nokwethembeka. Izindlu zamakamelo akabili we-transmitter ziqinisekisa ukwethembeka kanye nokuxilongwa okuthuthukile ukuze ugcine amaphuzu akho okulinganisa esebenza futhi. I-transmitter ihlanganisa ubuchwepheshe be-Rosemount X-well™ nenzwa ye-clamp ye-Rosemount 0085 ukukala ngokunembile izinga lokushisa lenqubo, isuse isidingo samashubhu ashisayo noma inqubo yokungena.

Izidlulisi zokushisa ze-Rosemount 644 ziyahlukahluka futhi zitholakala kusetshenziswa izivumelwano ze-HART™, FOUNDATION™ Fieldbus noma PROFIBUS™, ezinezitayela zokukhweza eziphezulu, zenkundla noma zesitimela nezinketho eziningi zezindlu. Ngokungeza i-Local Operator Interface (LOI), ukulungiselelwa komthumeli kungabuyekezwa ensimini ngaphandle kwamathuluzi. I-transmitter ihlanganisa nemisebenzi yokuxilonga efana ne-Hot Backup™, isexwayiso se-sensor drift kanye nokuwohloka kokusebenza kwe-thermocouple ukuze kuhlangatshezwane nezidingo ezahlukene zohlelo lokusebenza.
