Hauv kev tsim khoom lag luam, kev soj ntsuam kom raug ntawm cov kua theem thiab cov kev sib tshuam yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm kev tsim khoom thiab ua kom cov txheej txheem ua haujlwm zoo hauv cov khoom cia thiab kev tswj cov txheej txheem. Cov cuab yeej ntsuas qib qub feem ntau raug kev txom nyem los ntawm qhov tsis txaus, tsis zoo ib puag ncig hloov pauv, thiab kev teeb tsa nyuaj. Magnetostrictive qib gauges, raws li lub hauv paus ntsiab lus magnetostrictive siab, integrate core zoo xws li high precision, dav compatibility, thiab yooj yim installation, ua rau lawv nyiam cov khoom rau qib ntsuas nyob rau hauv ntau yam xws li roj av, tshuaj, hluav taws xob, thiab dej kho. Tsab ntawv xov xwm no yuav qhia meej txog cov txiaj ntsig kev lag luam thiab cov lus qhia tshwj xeeb ntawm cov khoom siv no los ntawm cov haujlwm xws li kev ua haujlwm, cov yam ntxwv tseem ceeb, cov xwm txheej siv tau, thiab kev ceev faj txog kev siv.
Txoj Cai Ua Haujlwm: Magnetostrictive Effects Enables Precise Sensing
Lub hauv paus ntsiab lus ntsuas ntawm magnetostrictive qib gauges stems los ntawm cov nyhuv magnetostrictive: ferromagnetic cov ntaub ntawv nthuav dav thiab cog lus loj nyob rau hauv lub zog ntawm sab nraud magnetic teb, rov qab mus rau lawv qhov qub ntev tom qab lub magnetic teb raug tshem tawm. Cov txheej txheem ua haujlwm yog raws li hauv qab no: Nyob rau hauv cov kab magnetostrictive ntawm tsis yog-magnetic sojntsuam, lub ntsiab tswj hluav taws xob hluav taws xob xa cov mem tes nqaim electromagnetic. Raws li cov mem tes propagates raws txoj kab magnetostrictive, nws cuam tshuam nrog lub magnetic teb generated los ntawm cov hlau nplaum nyob rau hauv lub ntab cim cov kua nto/interface, exciting ib tug torsional kev nyuaj siab yoj. Qhov kev ntxhov siab no rov qab mus rau lub sensor raws li txoj kab magnetostrictive. Lub tshuab hluav taws xob ntsuas qhov ntsuas lub sijhawm ntawm lub sijhawm sib kis thiab xa rov qab pulses, yog li txiav txim siab qhov chaw ntab, piv txwv li, qhov siab ntawm cov kua nto / qhov sib txuas.
Lub hauv paus ntsiab lus no ua kom ntseeg tau tias cov txheej txheem ntsuas tsis cuam tshuam los ntawm cov khoom siv physicochemical ntawm qhov nruab nrab, xws li qhov ntom ntom, viscosity, thiab conductivity, thaum ua tiav millisecond - qib teb thiab millimeter - qib raug, muab kev txhawb nqa rau kev ntsuas ruaj khov hauv kev ua haujlwm nyuaj.
