Nyob rau hauv ib tug multi-core cable, ib tug 4-20mA teeb liab khiav txoj cai ib sab ntawm ib tug 220V switching teeb liab. Lawv puas cuam tshuam ib leeg? Yog lawm. Lub teeb liab muaj zog ua rau muaj kev sib tham loj ntawm cov khub uas nyob ib sab.
Peb Pair Shielded Instrumentation Cable siv ib tus khub shielding qauv. Nws qhov ntsuas hluav taws xob yog 300/500V. Nws yog tsim rau precision ntsuas circuits uas xav tau kev tiv thaiv nruj tiv thaiv khub rau khub crosstalk. Piv txwv yog cov teeb liab tsis muaj zog kis tau los ntawm RTDs thiab thermocouples.
Txhua khub ntawm cov teeb liab xov hlau yog twisted nrog high precision. Cov khub sib txawv siv qhov sib txawv twist ntev. Cov twist ntev yog nruj me ntsis staggered. Qhov no txo cov electromagnetic coupling ntawm cov khub uas nyob ib sab.
Lub hauv paus yog ob txheej shielding. Sab nraum txhua khub twisted, peb qhwv los yog braid ib txheej shielding cais. Peb feem ntau siv aluminium yas composite daim kab xev qhwv nrog tin plated tooj liab ntws hlau. Kev pab mus txog 100%. Peb kuj tuaj yeem siv tooj liab hlau braid nrog kev pab ntawm 80% lossis ntau dua. Cov txheej thaiv thaiv no kaw txhua khub ntawm cov cim hauv nws lub tawb hlau.
Tom qab sib tw tag nrho cov khub tiv thaiv ua ke, peb tsis ntxiv ib daim ntaub thaiv npog tag nrho. Tom qab ntawd peb ncaj qha extrude PVC sheath.
Tus khub shielding qauv muab tsawg heev capacitive coupling thiab inductive coupling ntawm khub. Qhov ntsuas ze kawg ntawm crosstalk attenuation feem ntau yog ntau tshaj 60dB. Qhov no txhais tau hais tias txawm tias lub teeb liab millivolt RTD thiab lub teeb liab txuas rau / tawm hauv tib lub cable, lawv tsis cuam tshuam rau ib leeg.
Piv nrog rau tag nrho cov shielded cables, Cov Pair Shielded Instrumentation Cable yog yooj yim rau xaim. Cov xaim xaim ntawm txhua tus khub tiv thaiv txheej tuaj yeem tsim los ntawm nws tus kheej ntawm qhov chaw raws li xav tau. Lawv kuj tuaj yeem txuas mus rau qhov sib txawv muaj peev xwm sib txawv. Qhov no muab siab yooj.
Qhov ntsuas hluav taws xob yog 300/500V. Ua haujlwm kub yog 70 degree. Cov rwb thaiv tsev yog polyethylene. Qhov no muab cov rwb thaiv tsev tiv thaiv ntau dua lossis sib npaug rau 1000 MΩ·km. Yam tsawg kawg khoov vojvoog yog 6 npaug ntawm kab kab sab nraud.
Peb muaj ib tug tshwj xeeb kev tswj department. Lawv ua random checks. Peb muaj cov neeg ua haujlwm siab rau kev pab cuam tom qab muag. Peb lees txais kev tshuaj xyuas thib peb.
