Multi- cheeb tsam kub khiav kub controllers muaj kev ywj pheej ntawm kev nrhiav tau raws rau txhua qhov manifold thiab nozzle cua sov cheeb tsam, sib koom ua ke kaum ob ntawm cov teeb liab thermocouple ib txhij kom sib npaug ntawm qhov kub thiab txias faib thoob ntau- kab noj hniav pwm, tseem tsis tsim nyog teeb liab kev sib koom tes yooj yim ua rau hla - cheeb tsam qhov kub thiab txias tsis sib xws. Standard multi-zone systems muaj xws li los ntawm 12-zone me maub los rau 8-kab kab noj hniav ntim pwm mus rau 96-zone high-end industrial controllers rau 128-kab kab noj hniav micro electronic connector pwm, txhua channel ua ke nrog ib qho tshwj xeeb J/K thermocouple los sau cov ntaub ntawv kub tsis muaj kev sib koom.
Lub luag haujlwm tseem ceeb ntawm kev sib koom tes yog nyob ntawm kev ywj pheej PID kaw - voj tswj rau txhua qhov thermocouple channel. Txhua lub thermocouple xa tawm tiag tiag - lub sijhawm millivolt teeb liab rau nws cov khoom siv hluav taws xob tshwj xeeb, uas suav cov ntsuas kub sib txawv ntawm qhov kev nyeem ntawv tiag tiag thiab teeb tsa tus nqi, tom qab ntawd tso tawm cov kev hloov pauv hluav taws xob ywj pheej rau lub tshuab cua sov. Yooj yim qis- tus nqi tswj tau tsuas yog ua ib zaug xwb-channel kev cai ywj pheej yam tsis muaj kev sib txuas ntawm - cheeb tsam, uas ua haujlwm zoo rau cov khoom sib npaug sib npaug nrog cov cua sov tsis sib xws. Txawm li cas los xij, qhov loj asymmetrical manifolds rau tsheb bumpers tsim kev sib nrig sib thermal hluav taws xob ntawm cov cua sov uas nyob ib sab; Kev hloov kho PID standalone tsis tuaj yeem them tus ntoo khaub lig- thaj chaw tshav kub hloov pauv, ua rau qhov kub sib txawv ntawm 2-4℃ntawm cov kab noj hniav nyob sib ze.
Advanced ntse multi-zone controllers ntxiv inter-zone linkage coordination functions raws li multi-thermocouple data fusion. Lub kaw lus sau cov ntsuas kub los ntawm txhua lub thermocouples txhua 0.5 vib nas this, xam qhov tiag -lub sij hawm hluav taws xob hluav taws xob cuam tshuam coefficients ntawm cov cheeb tsam uas nyob ib sab, thiab tau zoo zoo -tunes lub tshuab hluav taws xob tso zis hluav taws xob kom offset hluav taws xob sib txawv nce lossis poob. Rau kev sib cais ntev ntev tshaj li 1.2 meters, tus maub los piv cov kev nyeem los ntawm manifold pem hauv ntej-kawg, nruab nrab thiab tus Tsov tus tw-kawg thermocouples, kho lub zog sib npaug kom sib npaug qhov kub poob raws qhov ntev khiav thiab txwv tag nrho - pwm kub sib txawv hauv ± 1℃. Dual-point thermocouple signals rau txhua lub nozzle kuj tau muab tso rau hauv kev sib koom ua ke, saib xyuas ob lub qhov rooj thiab lub qhov cub kub kom tiv thaiv kom tsis txhob muaj cua sov hauv zos ze ntawm cov koob valve.
Kev teeb pom kev sib cais tsim yog lub hauv paus kho vajtse ntawm kev ruaj khov multi-thermocouple kev sib koom tes. Txhua lub channel equips ywj siab lub teeb liab filtering circuits thiab cais transformers kom tsis txhob hla - tham cuam tshuam ntawm cov nyob ib sab thermocouple xov hlau bundled nyob rau hauv tib lub pwm hlau zawj. Tsawg-kawg pheej yig controllers tshem tawm channel cais modules; Thaum ib lub thermocouple tsim qhov txawv txav los yog luv luv - lub suab nrov hauv Circuit Court, qhov cuam tshuam tau kis mus rau txhua qhov chaw nyob ze, ua rau muaj qhov kub ntxhov thoob plaws hauv tag nrho cov manifold. Muab ob npaug rau- txheej tiv thaiv ntau- tub ntxhais thermocouple harnesses ntxiv dag zog rau cov teeb liab sib cais thaum lub sij hawm ntev - kis tau tus mob los ntawm pwm mus rau lub txee tswj.
Txias junction unified them nyiaj yog lwm qhov tseem ceeb ntawm kev sib koom tes txuas. Tus maub los lub sab hauv qhov ntsuas qhov ntsuas kub tau sau cov txee ambient kub raws li kev sib koom ua ke txias sib txuas siv rau tag nrho cov thermocouple raws, tau txais kev kho qhov tsis raug cuam tshuam los ntawm lub caij ua haujlwm kub hloov pauv rau txhua cheeb tsam ib txhij. Yog hais tias sib txawv thermocouple extension cables ntawm inconsistent specifications yog sib tov, lub unified them algorithm yuav tsim ib tug tsis sib npaug kev kho qhov tseem ceeb nyob rau hauv raws, ua rau inconsistent kub bias ntawm kab noj hniav. Standardized uniform hlau specifications rau tag nrho cov cheeb tsam tshem tawm qhov kev sib koom ua yuam kev.
Cov kauj ruam ua haujlwm niaj hnub ua kom zoo rau ntau yam -thermocouple kev sib koom ua ke cuam tshuam: tom qab pwm cua sov rau qhov kub thiab txias, tswj qhov kub thiab txias rau 30 feeb, kaw tag nrho cov thermocouple nyeem, thiab qhib lub tshuab hluav taws xob nws pib- sib npaug ua haujlwm los kho lub hauv paus fais fab rau txhua cheeb tsam. Lub hli calibration sib sau ua ke cov teeb liab raug ntawm tag nrho cov thermocouple sojntsuam kom tsis txhob muaj kev sib txawv ntawm tus kheej los cuam tshuam kev sib koom ua ke tag nrho. Kev tshawb fawb ntau- cheeb tsam teeb liab kev sib koom ua ke kom ntseeg tau tias qhov kub thiab txias nyob rau hauv txhua qhov kab noj hniav ntawm complex multi-kab kab noj hniav kub khiav pwm, zoo heev txhim kho qhov sib xws thiab txo cov sorting workload rau cov pwm pwm.
