Kutentha kwa Transmitter

Rosemont 214C thermistor sensor sensor imagwiritsa ntchito Pt-100 unit kapena dual-element thermistor (RTD), yophimba kutentha kuchokera -196 mpaka 600 ° C (-321 mpaka 1112 ° F). Sensa iyi ndi yankho lapadera lomwe limagwiritsa ntchito mawonekedwe a filimu yopyapyala komanso mabala, kukulitsa kusinthasintha kwa ntchito. Sensa iyi ili ndi njira zambiri zosinthira, kuphatikiza kulondola kwa sensa ya Giredi A kapena Grade B, komanso imapereka Calendar-Van Dusen mosadukiza kwa ma transmitter - sensa yofananira kuti ikwaniritse kulondola kwambiri.

Imathandizira kuyika kwa thermocouple, kukana kwamafuta, magetsi a DC kapena ma siginecha okana.
Kutembenuzidwa kukhala 4-20 mA DC chizindikiro kapena kutulutsa siginecha ya fieldbus.
Imagawidwa mumtundu wa HART wolankhulana ndi mtundu wa FOUNDATION TM wolumikizana ndi mabasi.
Mtundu wolumikizirana wa HART umagwirizana ndi chitetezo cha SIL2.

YTA610 imapereka kulondola kwakukulu, kukhazikika, komanso kudalirika. Kapangidwe ka nyumbayo kamakhala kodalirika kokhala ndi zipinda ziwiri. Kulowetsa kwa sensor kumatha kukhala kusankha kolowera kamodzi kapena kawiri. Izi zitha kuvomereza RTD, thermocouple, ohm, kapena DC millivolt. Imatembenuza zolowetsa sensa kukhala 4 mpaka 20 mA DC chizindikiro cha analogi kapena chizindikiro cha digito cha Fieldbus. HART 7 Protocol kapena FOUNDATION™ Fieldbus ITK 6 version ilipo. Kulowetsa kwapawiri kumatha kuvomereza kuwerengera kwa masensa awiri a kusiyanitsa kapena mtengo wapakati ndi ntchito yosunga zosunga zobwezeretsera. Sensor zosunga zobwezeretsera zimagwira ntchito kuti zisinthidwe zokha kuchokera koyambira kupita ku zosunga zobwezeretsera pakalephera kwa sensor. Mwa kutengera kusintha kwa magawo am'deralo pa Indicator, kumakhala kosavuta kuchita ntchito yokhazikitsa patsamba.

YTA710 imakhala yolondola kwambiri, yokhazikika komanso yodalirika kwambiri. Chigobacho chimagwiritsa ntchito chodalirika cha zipinda ziwiri. Kulowetsa kwa sensor kumatha kusankhidwa ngati kulowetsa kamodzi kapena kawiri. Itha kuvomereza ma signature osiyanasiyana monga RTD, thermocouple, resistance, ndi DC voltage. Imatembenuza zolowetsa sensa kukhala 4-20 mA DC analogi siginecha kapena fieldbus digito chizindikiro. HART 7 protocol, BRAIN protocol kapena FOUNDATION™ Fieldbus ITK 6 yaperekedwa. Kulowetsa kwapawiri kumatha kuvomereza kusiyanitsa kapena kuwerengera kwapakati pa masensa awiri ndikuzindikiranso ntchito yosunga zosunga zobwezeretsera. Ntchito yosunga zobwezeretsera sensor imagwiritsidwa ntchito kuti ingosintha kuchokera pachida chachikulu kupita ku chipangizo chosungirako pamene sensa ikugwira ntchito. Magawo omwe ali patsamba akhoza kukhazikitsidwa pogwiritsa ntchito batani la magawo omwe ali patsamba pa chizindikirocho.

The Rosemount 248 kutentha transmitter, monga njira yothetsera makampani, akhoza kupereka mosasinthasintha ndi odalirika ntchito chilengedwe ndondomeko. Mapangidwe a njanji ya DIN yophatikizika ndiyosavuta kuyiyika komanso yogwiritsidwa ntchito mosiyanasiyana, ikukwaniritsa zofunikira zoyezera kutentha kwa mfundo imodzi.

Chopatsira kutentha cha Rosemount 3144P chimakupatsirani miyeso yotsogola yamabizinesi yolondola, yokhazikika komanso yodalirika. Nyumba zokhala ndi zipinda ziwiri za transmitter zimatsimikizira kudalirika komanso kuwunika kwapamwamba kuti miyeso yanu isayende bwino. Transmitter imaphatikiza ukadaulo wa Rosemount X-well™ ndi Rosemount 0085 clamp sensor kuti muyeze molondola kutentha kwadongosolo, kuchotsa kufunikira kwa machubu otentha kapena kulowa mkati.

Ma transmitters otentha a Rosemount 644 ndi osunthika ndipo amapezeka pogwiritsa ntchito ma protocol a HART™, FOUNDATION™ Fieldbus kapena PROFIBUS™, okhala ndi masitaelo apamwamba, akumunda kapena njanji komanso zosankha zingapo zanyumba. Powonjezera Local Operator Interface (LOI), kasinthidwe ka transmitter kumatha kusinthidwa m'munda popanda zida. Ma transmitter amaphatikizanso ntchito zowunikira monga Hot Backup ™, chenjezo la sensor Drift ndi kuwonongeka kwa magwiridwe antchito a thermocouple kuti akwaniritse zofunikira zosiyanasiyana zogwiritsira ntchito.
