Thermistors thiab thermocouples feem ntau txuas nrog PLCs los ntawm kev xa tawm

Thermistors thiab thermocouples feem ntau txuas nrog PLCs los ntawm kev xa tawm

Cov input modules rau thermal resistance thiab thermocouple sib haum PLC kuj txawv, uas tsis yog ib qho teeb meem, tab sis feem ntau PLC txuas ncaj qha mus rau ib tug 4-20mA teeb liab, thaum lub thermal resistance thiab thermocouple feem ntau txuas nrog. lub transmitter. Yog tias koj txuas rau DCS, koj tsis tas yuav siv lub transmitter! Thermistor yog RTD teeb liab, thermocouples yog TC teeb liab!

Lub PLC kuj muaj cov thermal resistance module thiab cov thermocouple module, uas tuaj yeem ncaj qha tawm tswv yim tiv thaiv thiab coupling teeb liab. Muaj ntau hom thermocouples xws li j, t, N, K, s, thiab lwm yam. Qee qhov kim tshaj li cov tub rog tiv thaiv, thaum lwm tus yog pheej yig dua li cov tub rog tiv thaiv. Txawm li cas los xij, yog tias cov xaim them nyiaj suav nrog, tag nrho cov nqi ntawm cov thermocouples yog siab dua. Lub thermistor yog lub teeb liab tsis kam, thaum lub thermocouple yog lub teeb liab voltage.

Xaiv qhov ntsuas qhov ntsuas qhov tseeb thiab ntsuas qhov ntsuas kub

Thaum ua haujlwm kub yog 1300 ~ 1800 degree thiab qhov yuav tsum tau muaj qhov tseeb yog siab, B-hom thermocouples feem ntau xaiv; Thaum qhov tseeb tsis siab thiab cov cua tso cai, tungsten rhenium thermocouples feem ntau yog siv; Thaum qhov kub siab tshaj 1800 degree, tungsten rhenium thermocouples feem ntau yog siv; S-hom thermocouples thiab n-hom thermocouples tuaj yeem siv thaum ua haujlwm ntawm qhov kub ntawm 1000 txog 1300 degree; K-hom thiab n-hom thermocouples feem ntau yog siv rau qhov kub qis dua 1000 degree thiab 400 degree, thaum E-hom thermocouples feem ntau siv. Thaum ntsuas ntawm 250 degree thiab qhov kub tsis zoo, T-hom thermocouples feem ntau yog siv. Ntawm qhov kub thiab txias, T-hom thermocouples ruaj khov thiab muaj qhov tseeb.

Kev ntsuas kub ntawm cov khoom txav, cov khoom vibrating, thiab cov thawv ntim siab yuav tsum muaj zog txhua yam. Rau cov huab cua uas muaj tshuaj lom neeg muaj kuab paug, yuav tsum muaj cov raj tiv thaiv, thiab kev rwb thaiv tsev siab yog xav tau thaum muaj hluav taws xob cuam tshuam. Cov txheej txheem xaiv: Qauv - Tus lej kawm tiav - qib pov thawj tawg - qib raug - Kev teeb tsa thiab kho daim ntawv - cov khoom siv tiv thaiv tube - Ntev lossis qhov tob tob.

Hluav taws xob cua sov raj tau siv dav hauv kev lag luam cua sov ib puag ncig!

Hluav taws xob cua sov kav yog dav siv nyob rau hauv industrial cua sov ib puag ncig. Txhawm rau siv nws kom raug, tsuas yog them me ntsis xwb. Hluav taws xob cua sov raj yog hom hluav taws xob cua sov siv nyob rau hauv ntau yam khoom siv hluav taws xob cua sov, thiab tuaj yeem siv sib cais. Ua ntej, ua tib zoo saib xyuas qhov muab cov hlau tsis muaj hluav taws xob hluav taws xob tso rau hauv dej, thiab tom qab ntawd ntsaws rau hauv (lub hwj chim rau) kom tiv thaiv lub raj cua sov los ntawm tawg thaum ntsib dej txias. Txhawm rau kom tsis txhob muaj kev puas tsuaj rau cov hlau tsis muaj hluav taws xob hluav taws xob cua sov vim qhov cua sov qeeb qeeb, tshaj qhov tso cai rau cua sov.

Qhov kawg ntawm lub tshuab hluav taws xob cua sov yuav tsum tau ceev kom huv si thiab qhuav. Nyob rau hauv cov kua lossis roj ib puag ncig xws li tshuaj lom neeg corrosion, flammability, thiab tawg, qhov cua sov ntawm stainless hlau hluav taws xob cua sov kav yuav tsum tau muab tso rau hauv cov cua kub nruab nrab, txwv tsis pub nws yuav txo cov rwb thaiv tsev thiab ua rau luv luv Circuit Court breakdown. Cov xaim ib feem ntawm cov kav hlau tsis muaj hluav taws xob cua sov yuav tsum nruj me ntsis tiv thaiv nrog cov khoom siv rwb thaiv tsev kom tiv thaiv kev raug mob.
