Integrated Temperature Transmitter

(Integrated Thermocouple / RTD)

Txheej txheem cej luam

Lub thermocouple ntsuas qhov ntsuas kub raws li qhov ntsuas kub, tso tawm qhov tsis yog -mV teeb liab uas hloov mus rau qhov ntsuas kub sib xws los ntawm kev tshuaj xyuas nws cov lus ntsuas ntsuas.An RTD (Resistance Temperature Detector) ntsuas qhov ntsuas kub raws li qhov tsis kam tiv thaiv-kub yam ntxwv ntawm cov ntaub ntawv, outputting ib noncal{3} ib lub teeb liab kuj.

Ob qhov no tsis yog - txoj hauv kev uas yuav tsum tau ntsuas lub rooj ntsuas ntsuas ua rau muaj ntau qhov tsis yooj yim hauv cov ntawv loj -, tshwj xeeb tshaj yog txwv lub computer -raws li cov zaub, xam, thiab tswj.

Ib qho kev sib xyaw ua ke thermocouple / RTD nrog lub ntsuas kub yog qhov tseem ceeb ntawm thermocouple lossis RTD nrog lub ntsuas kub transmitter nruab rau hauv nws lub davhlau ya nyob twg lub taub hau.Qhov tsis yog -linear teeb liab los ntawm thermocouple / RTD yog hloov los ntawm lub transmitter module rau hauv ib lub teeb, linear, standardized tso zis teeb liab rau ib qho yooj yim zaub, tej thaj chaw deb kis tau tus mob, teeb liab sib qhia ncaj qha. lub rooj, thiab cov khoom muaj kev sib hloov tau zoo heev.Piv txwv li, ib qho kev sib xyaw thermocouple nrog ntau yam ntawm 0 ~ 300℃tuaj yeem hloov nrog kev sib xyaw Pt100 RTD nrog tib yam 0 ~ 300℃ntau yam.

Linear kev sib raug zoo: txhais tau hais tias ob qhov sib txawv muaj thawj - kev sib raug zoo ntawm kev txiav txim, qhia raws li: y=ax + b qhov twg a thiab b yog qhov tsis tu ncua, thiab y thiab x yog ob qhov sib txawv (xws li ntsuas qhov nruab nrab kub thiab cov teeb liab tawm).

Txoj Cai Ua Haujlwm ntawm Temperature Transmitter

Kev faib tawm ntawm Integrated Thermocouple / RTD

Integrated thermocouples thiab RTDs ntxiv qhov kub thiab txias ua haujlwm lossis ntawm -qhov chaw tso saib ua haujlwm rau tus qauv thermocouples/RTDs.Tshwj xeeb, lub ntsuas kub ntawm lub tshuab hluav taws xob thiab/lossis lub taub hau zaub tau teeb tsa hauv thawj lub davhlau ya nyob twg lub taub hau. Hauv kev siv tswv yim, muaj 6 hom:

Kev ntsuas ntau yam ntawm Integrated Thermocouple / RTD

Kev ntsuas ntau ntawm kev sib xyaw ua ke thermocouple / RTD yog ncaj qha ntsig txog cov qauv tso zis teeb liab thiab yuav tsum tau qhia meej meej thaum xaiv.

Qhov ntau ntawm qhov ntsuas kub thiab ntsuas qhov ntsuas ntawm lub thermocouple / RTD yog ob lub ntsiab lus sib txawv:

Kev ntsuas ntau: qhov ua haujlwm siab tshaj plaws

Transmitter ntau yam: qhov xav tau ua haujlwm ntau yam (ib ntu hauv qhov ntsuas ntau)

Piv txwv li: A Hom K thermocouple muaj qhov ntsuas ntau ntawm 0 ~ 1200 degree, tab sis qhov kev ua haujlwm tiag tiag yog 0 ~ 900 degree, yog li cov khoom xa tawm tuaj yeem teeb tsa rau 0 ~ 1000℃sib haum rau 4 ~ 20mA.

Txhawm rau txhim kho kev daws teeb meem, qhov ntau tuaj yeem nqaim kom tsom mus rau qhov chaw ua haujlwm tseem ceeb.Piv txwv li, tungsten-rhenium thermocouple rau kev tswj qhov kub thiab txias muaj qhov ntsuas ntau ntawm 0 ~ 2100 degree, nrog rau ntu ua haujlwm tseem ceeb ntawm 1400 ~ 1600℃.Txhawm rau kev tswj qhov tseeb, qhov transmitter range tuaj yeem teem rau 1700 ~ 1600 degree.

Tam sim no, taag-ntaus transmitters tau dav siv; Lawv qhov ntau yam tsis tuaj yeem hloov pauv ib zaug.Digital programmable thiab kev sib txuas lus-enabled transmitters tso cai rau kho cov teeb liab tawm tswv yim thiab cov zis ntau raws li xav tau.

Kev ntsuas kub

Kev ntsuas ntau thiab cov zis tam sim no yog linearly proportional:

Yam tsawg kawg nkaus → 4mA

Qhov siab tshaj plaws → 20mA

Piv txwv: 0 ~ 600℃sib raug rau 4 ~ 20mA.At 200℃:I=4+(20−4) × 600200​=9.333mAConversely, yog qhov ntsuas tam sim no yog 9.333mA: degree

Pom zoo ntsuas qhov ntsuas
