Kub khiav sensors puas tuaj yeem kho tom qab kev laus?

Tom qab lawv muaj hnub nyoog, feem ntau ntawm cov kub khiav sensors tsis tuaj yeem kho. Nws yog qhia kom pauv lawv tawm rau tshiab sensors nrog tib specs. Raws li qhov xwm txheej ceev, tsuas yog qee qhov me me ntawm cov teeb meem kev laus uas tsis yog - tseem tuaj yeem kho tau ib ntus. Cov xwm txheej tshwj xeeb muaj xws li hauv qab no:

1. Vim li cas cov sensors qub feem ntau tsis kho?

Kev laus kub khiav sensors, uas feem ntau yog K-hom thermocouples lossis PT100 RTDs, qhia txog kev puas tsuaj mus tas li ntawm qhov kev sojntsuam qhov tseem ceeb:

Ntev-lub sij hawm siab- kub oxidation thiab corrosion ua rau muaj kev hloov pauv hauv cov thermocouple xov ntawm K- hom thermocouples, uas ua rau irreversible rhiab heev deterioration;

Ntev -lub sij hawm thermal expansion thiab contraction ua rau platinum xov hlau ntawm RTDs khoov, ua rau irreversible kuj drift;

Txo kev sojntsuam thermal conductivity, insulating txheej deterioration, thiab cov khoom siv dav dav yog txhua yam qhia tias qhov tseeb tsis tuaj yeem rov qab los ntawm kev kho.

Nws tsuas tuaj yeem txhawb nqa qhov tseeb ib ntus, txawm tias rov ua dua. Tom qab ib mus rau ob lub lis piam, qhov sib txawv yuav nce ib zaug ntxiv, ua rau ntev - lub sij hawm ntau lawm tsis tuaj yeem ua kom ntseeg tau.

2. Qee qhov xwm txheej yuav tsum tau kho tam sim

Kev kho xwm txheej ceev ib ntus tuaj yeem ua tau yog tias qhov teeb meem tshwm sim los ntawm kev laus los yog xoob ntawm cov hlua hluav taws xob es tsis yog kev laus ntawm kev sojntsuam nws tus kheej:

Tshem tawm cov sensor thaiv cov terminals thiab xuab zeb hauv cov pins corroded tom qab kaw lub hwj chim.

Ntxuav cov pa roj carbon monoxide los yog cov roj sib xyaw ua ke hauv lub thawv davhlau ya nyob twg thiab muab cov xaim nruj dua.

Txheeb xyuas qhov ntsuas kub ntsuas qhov sib txawv tom qab calibration. Nws tuaj yeem siv tau ib ntus yog tias qhov deviance poob rov qab rau hauv 5 degree, tab sis kev hloov pauv tseem yuav xav tau tom qab.

Tab sis qhov no tsuas yog qhov teeb meem nrog cov khoom sib txuas sab nraud, tsis yog qhov qhia tau tias cov tub ntxhais soj ntsuam tau laus dua.

3. Qhia txog kev tswj kom tsim nyog tom qab kev laus

Txhawm rau kom ntseeg tau tias qhov ntev ntawm qhov kev teeb tsa thiab hom teeb liab sib haum thiab tiv thaiv kev sib raug zoo nyuaj, muab qhov tseem ceeb rau kev hloov nrog cov khoom siv qub qub (OEM) sensors ntawm tib lub ntsiab lus.

Rov xyuas qhov ntsuas kub ntsuas qhov sib txawv tom qab hloov. Kev tsim khoom tuaj yeem pib sai li sai tau thaum qhov kev sib txhuam kub tsis raug raug txheeb xyuas kom nyob hauv +5℃.

Kev sib hloov batch yog qhia rau cov sensors uas tau ua haujlwm rau peb mus rau tsib xyoos txhawm rau tiv thaiv cov teeb meem tsis zoo los ntawm ib qho kev laus tsis ua haujlwm.
