Cov khoom sib khi siab-precision resistors tuaj yeem siv los txhim kho lub sijhawm ntev ntawm cov pyrometer.
Kev ntsuas qhov kub thiab txias nrog platinum tiv thaiv tus pas ntsuas kub yuav tsum tau ntsuas qhov ntsuas qhov ntsuas tau zoo heev. Yuav kom ua tiav qhov tseeb ntawm {{0}}.001 degree, kev lag luam tus qauv Pt-100 sojntsuam ntawm 0 degree yuav tsum muaj qhov tseeb ntawm 4 ppm ntawm tus nqi tsis kam. Nrog rau qhov kev tshwm sim ntawm niaj hnub 24-ntsis sigma-delta analog-rau-digital converters, qhov tseeb no tau ua kom yooj yim dua, thiab niaj hnub no qhov kev sib tw tseem ceeb yog los xyuas kom meej luv luv thiab ntev drift.
Batemika tau pib ua ntej qhov kev txhim kho ntawm UT-ONE series ntawm cov ntsuas kub nrog tag nrho cov ntawv nyeem qhov tseeb ntawm tsawg dua 0.01 degree . Thawj tiam ntawm UT-ONE cov khoom siv tam sim no muaj. Thawj tiam ntawm UT-ONE cov cuab yeej muaj peev xwm ua tau raws li qhov xav tau kev daws teeb meem zoo thiab lub sijhawm luv luv, tab sis tau daig nrog qhov tsis muaj peev xwm ua tiav qhov kev cia siab rau lub sijhawm ntev drift.Qhov kev ntsuas Circuit Court rau UT-ONE ntsuas ntsuas ntsuas ntsuas yog raws. ntawm 24-ntsis sigma-delta analog-rau-digital converter hauv 4-wire ratiometric configuration.
Qhov zoo ntawm qhov kev teeb tsa no yog qhov tseeb ntawm qhov tam sim no thiab lub suab nrov qis tsis cuam tshuam rau qhov ntsuas ntsuas. Lub sij hawm ntev drift tsuas yog txiav txim siab los ntawm kev siv resistor thiab programmable amplifier, tab sis tib lub sij hawm qhov drift tshwm sim los ntawm ob qho no tsis tuaj yeem paub qhov txawv. Nyob rau hauv ib tug thaum ntxov tsim, cov ntaub ntawv resistor yog ib tug SMR3DZ ntawv ci resistor nrog ib tug load lub neej ntawm 50 ppm (70 degree, 2000 teev ntawm rated zog).
Cov neeg siv khoom xav kom cov resistor ruaj khov ntawm kwv yees li 10 txog 20 ppm ib xyoos twg. Cov txiaj ntsig ntev drift tau lees paub qhov kev kwv yees yav dhau los. Lub sij hawm ntev drift muaj kev hloov pauv txhua xyoo, tej zaum cuam tshuam nrog cov av noo hloov vim lub caij nyoog. Lub drift tsis muaj qhov tshwj xeeb sib txawv thiab tsis sau ntau xyoo.
VPG foil resistor teb tsim engineer tau txais cov txiaj ntsig tau ntev ntev thiab hais kom cov neeg siv khoom hloov SMR3DZ molded chip foil resistor nrog VHP101T kaw ntawv ci resistor los txhim kho lub sijhawm ntev. Thaum kawg, tus neeg siv khoom tau coj tus qauv ntawm VHP101T 100Ω resistor rau kev ntsuam xyuas. Lub resistor tau muab tso rau hauv ib lub thawv me me uas muab kev tiv thaiv zoo txhua yam thiab hluav taws xob rau cov resistor, sib txuas nrog lub pyrometer raws li tus qauv ntsuas. Qhov ntsuas kub mus sij hawm ntev ntawm cov qauv no tsawg dua 1 ppm hauv ib xyoos.
Amazed by the performance of the VHP101T, Batemika intends to replace the reference resistor in one of the components within the UT-ONE with the VHP101T. Exceeding the customer's expectations, the long term drift results have improved dramatically. The coordinates at the same scale give us a clear picture of the comparison. The long term drift was reduced from >20ppm ib xyoos rau tsawg dua 5ppm ib xyoos twg. VHP101T resistor kuj coj tau zoo dua lub sij hawm luv luv thiab qis dua pib drift, uas ua rau cov neeg siv khoom muaj kev ntseeg siab rau lawv cov txheej txheem tswj kom zoo. batemika tam sim no tsuas yog siv VHP101T resistor raws li qhov siv resistor nyob rau hauv lub pyrometer thiab txawm refurbished ib pawg ntawm cov uas twb muaj lawm.
Qhov no raws li cov lus qhia ntawm VPG foil resistor teb tsim engineer? --Lub sab hauv siv resistor ntawm cov khoom tau hloov nrog Vishay Foil Resistor VHP101T hermetically kaw hlau ntawv nyiaj resistor, uas zoo heev txhim kho lub sij hawm ntev stability ntawm tag nrho cov cuab yeej thiab ua qhov sib txawv loj rau qhov ntsuas, ua pov thawj rau tus neeg siv khoom ib zaug ntxiv qhov kev ruaj ntseg ntev ntev ntawm cov ntawv ci resistor.
