Dab tsi yog qhov tshwm sim ntawm kev sib tiv tauj ntau dhau ntawm qhov kub khiav sensor aperture?

In addition to accelerating sensor aging and failure, excessive contact force (>15N) nyob rau hauv qab ntawm ib tug kub khiav sensor aperture yuav ua rau anomalous kub nyeem ntawv thiab cov yam ntxwv puas. Cov hauv qab no yog cov kev cuam tshuam tshwj xeeb:

1. Kev txo qis sensor lifespan: Lub sensor sojntsuam vaj tse thiab cov khoom siv sab hauv (cov txheej txheem rwb thaiv tsev, txuas xaim / platinum xaim) yuav muaj kev ntxhov siab ntev ntev thaum lub zog tiv tauj hnyav. Nyob rau hauv lub kub khiav rov qab kub thiab txias mus, uas tsim thermal expansion thiab contraction:

Lub sensor lub neej yuav raug txo los ntawm 30% mus rau 50% vim yog kev sib txuas nrog cov hlau / platinum hlau muaj zog tuaj yeem ua rau deformation thiab tawg. Ib mus rau ib thiab ib nrab xyoo yuav dhau mus ua ntej lub sensor uas tuaj yeem kav peb xyoos tsis ua haujlwm;

Compression yuav ua mob rau cov txheej txheej insulating, uas ua rau cov teeb liab dhia, sab hauv luv luv Circuit Court, thiab qhov kub tsis zoo hloov pauv.

2. Ua rau qhov ntsuas kub tsis raug

Lub ntsiab lus ntawm lub cev tus yam ntxwv yog hloov los ntawm kev sib zog ntau dhau:

Cov khoom siv hluav taws xob ntawm cov thermocouples tau hloov pauv los ntawm kev khoov ntawm cov thermocouple hlau nyob rau hauv kev ntxhov siab, uas ua rau muaj qhov sib txawv ntawm qhov ntsuas kub uas tsis ruaj khov txawm tias tom qab calibration.

Compression ntawm platinum xaim hloov qhov tsis kam ntawm qhov ntsuas kub tsis kam (RTDs), ua rau lub teeb liab kub uas tsis tshua muaj siab thiab tsis raug sawv cev rau qhov kub ntawm qhov tseeb.

3. Ncaj nraim ua rau kev puas tsuaj rau cov cuab yeej siv tshuab

Kev sib tiv tauj ntau dhau tuaj yeem yooj yim tsoo lub sensor lub tsev tsis muaj steel hlau lossis tseem tawg qhov kev sojntsuam hauv cov ntsia hlau teeb -mounted installation, ua rau lub sensor tag nrho tsis ua haujlwm.

Nyob rau hauv qhov xwm txheej hnyav, overtightening yuav strip lub mounting qhov threads, ua phem rau pwm lub installation qauv, yuav tsum re-tapping thiab kho, thiab ncua ntau lawm.

4. Ua kom muaj feem cuam tshuam ntau lawm

Kev sib tiv tauj ntau zaus ua rau muaj kev puas tsuaj loj. Kev sib txawv me me yog qhov nyuaj rau pom thaum xub thawj, tab sis lawv maj mam nce tus nqi ntawm cov khoom tsis xws luag, uas tuaj yeem ua rau batch zoo seem thiab poob ntau lawm.
