Khoom Description
Manganin tooj liab shunt resistors yog precision tam sim no sensing Cheebtsam engineered rau daim ntaub ntawv uas ncaj ammeter ntsuas yog impractical los yog tsis zoo. Cov cuab yeej no muab txoj hauv kev txhim khu kev qha rau kev saib xyuas cov tam sim no siab uas yuav ua rau muaj kev puas tsuaj rau cov qauv ammeters -txawm yog vim muaj qhov loj me ntawm qhov tam sim no lossis qhov muaj qhov dav dav. Los ntawm kev muab ib qho kev paub, ruaj khov qis- txoj kev tiv thaiv, peb cov Manganin shunts pab kom muaj kev txiav txim siab tam sim no los ntawm kev ntsuas qhov ntsuas hluav taws xob yooj yim.
Yuav ua li cas lub Shunt Resistor ua haujlwm
Lub shunt resistor ua haujlwm ntawm lub hauv paus ntsiab lus ncaj qha: nws tsim txoj kev bypass rau feem ntau ntawm cov khoom siv hluav taws xob tam sim no, tsuas yog ib qho me me, qhov ntsuas qhov sib npaug kom ncav cuag qhov ntsuas ntsuas. Qhov hluav taws xob poob thoob plaws lub shunt yog ncaj qha proportional rau tam sim no ntws los ntawm nws, raws li Ohm txoj cai (I=U/R).
Peb Manganin Copper Shunt nta lub cev sib txawv uas ua rau nws sib nrug ntawm cov qauv resistors. Nws suav nrog ob lub davhlau ya nyob twg loj txuas nrog ib lossis ntau dua precision hlau strips. Qhov kev tsim no tsis yog tsuas yog kho kom zoo nkauj xwb- nws ua haujlwm rau lub hom phiaj tseem ceeb. Qhov tsis kam ntawm ib qho hlau yog qhov sib npaug ntawm nws tus ntoo khaub lig- ntu ntu; Yog li ntawd, tus naj npawb ntawm strips ncaj qha txiav txim siab tus nqi ntawm shunt. Cov strips ntau dua ua rau qis qis dua, ua rau lub cuab yeej siv cov khoom siv hluav taws xob ntau dua nrog cov hluav taws xob tsawg tsawg.
Vim li cas Manganin?
Cov khoom tiv thaiv hauv peb cov shunts yog tsim los ntawm Manganin- tooj liab tshwj xeeb -manganese-nickel alloy (feem ntau muaj li ntawm 84% tooj liab, 12% manganese, thiab 4% npib tsib xee). Cov khoom no yog tus qauv kev lag luam rau precision shunt resistors vim muaj ntau yam zoo:
Exceptionally Low Temperature Coefficient of Resistance (TCR)
Manganin tswj kev ruaj khov zoo kawg nkaus nyob rau hauv qhov kub thiab txias, feem ntau ± 15 ppm / degree. Qhov no ua kom qhov ntsuas qhov tseeb nyob ib puag ncig tsis hais qhov ntsuas qhov kub thiab txias.
Superior Ntev -Lub Sij Hawm Stability
Manganin resistors qhia tau zoo heev tiv thaiv kev ruaj ntseg nyob rau lub sij hawm ntev, ua rau lawv zoo tagnrho rau cov ntawv thov kom ntseeg tau, rov ntsuas dua.
Tsawg Thermal EMF
Thermoelectric voltage generated ntawm Manganin thiab tooj liab yog qhov tsawg heev (feem ntau tsawg dua 3 µV / degree), tiv thaiv kev ntsuas tsis raug los ntawm qhov kub thiab txias ntawm cov ntsiab lus sib txuas.
Ntsiab nta & Cov txiaj ntsig
Tus qauv kam rau ua ntawm ± 0.25% xyuas kom meej millivolt tso zis hloov pauv ntawm thawj DC system tam sim no
Muaj cov kev teeb tsa txhawb nqa tam sim no los ntawm 15A txog 1,000A thiab tshaj
Muaj nyob rau hauv 50mV, 100mV, los yog kev cai tso zis kev ntsuam xyuas kom haum rau ntau yam kev cai
Sib cais terminals rau tam sim no thiab voltage sensing tshem tawm cov hlau lead tsis raug, xyuas kom meej ntsuas precision
Pav ca, compact qauv minimizes inductance rau compatibility nrog siab - zaus daim ntawv thov

Kev xaiv xaiv
Thaum xaiv tus shunt resistor rau koj daim ntawv thov, xav txog cov hauv qab no tsis:
Rated Tam sim no
Qhov siab tshaj plaws nruam tam sim no lub shunt tuaj yeem ua haujlwm
Cov zis hluav taws xob
Feem ntau 50mV lossis 100mV ntawm qhov ntsuas tam sim no
Kev khiav hauj lwm qhov kub thiab txias
Kev ua haujlwm txheem los ntawm +30℃mus rau +70 degree
Derating
Rau kev ua haujlwm tas mus li, nws raug nquahu kom ua haujlwm shunts tsis pub ntau tshaj ob -feem peb ntawm cov ntsuas tam sim no kom ntseeg tau tias lub neej ntev
