Ib feem tseem ceeb ntawm lub tshuab ntsuas qhov hnyav ntau lub taub hau yog lub sensor, uas feem ntau hu ua lub load cell. Lub load cell yog ib feem tseem ceeb ntawm lub tshuab ntsuas qhov hnyav ntau lub taub hau, thiab nws txoj haujlwm tsis tsawg dua li "lub siab tib neeg", nws yog ib qho tseem ceeb rau kev txiav txim siab seb qhov hnyav ntawm cov khoom puas ua tau raws li tus qauv. Yog tias lub sensor ntsuas qhov hnyav tsis ua haujlwm, nws yuav nyuaj rau peb kwv yees tias nws yuav ua rau poob ntau npaum li cas rau kab ntau lawm. Yog li ntawd, cov neeg siv yuav tsum sim cov khoom tseem ceeb no tas li. kom txo qhov poob. Niaj hnub no, Zhongshan Smart weigh yuav coj koj mus saib yuav ua li cas daws qhov teeb meem ntawm lub sensor tsis ua haujlwm ntawm lub tshuab ntsuas qhov hnyav ntau lub taub hau. 1. Zero point output Tshawb xyuas qhov zero point output, uas yog, tus nqi tso zis ntawm lub sensor hauv qhov xwm txheej tsis muaj load, thiab sim cov zis ntawm lub sensor hauv qab qhov xwm txheej uas txhua qhov thauj khoom (suav nrog cov khoom thauj zoo li qub xws li nplai thiab cov khoom xa mus rau lub zog) yuav tsum tau tshem tawm.

Lub ntsiab lus xoom ntawm lub sensor yuav tsum yog tus nqi tau los ntawm kev sim hauv lub xeev xav tau los ntawm kev tsim, kev teeb tsa thiab kev siv ntawm lub sensor kom tiv thaiv kev cuam tshuam tsis raug los ntawm qhov hnyav ntawm lub sensor nws tus kheej. 2. Sim qhov tsis kam ntawm rwb thaiv tsev Feem ntau, peb yuav tsum sim qhov impedance ntawm cov hlau txhuas ntawm lub sensor thiab lub cev sensor (elastomer, plhaub, thiab lwm yam). Nco ntsoov, txiav lub sensor ntawm lub thawv sib txuas thiab lub 'meter'.

Debug lub thawv kuaj rwb thaiv tsev (meter), tom qab ntawd txuas ib kawg ntawm cov hlau sim rau lub sensor cable (tso zis, nkag, hlau tiv thaiv, thiab lwm yam), thiab lwm qhov kawg rau lub cev sensor (elastomer, plhaub, thiab lwm yam). Raws li qhov yuav tsum tau ua dav dav, qhov impedance no ≥ 5000MΩ. 3. Kev kuaj choj impedance Kev kuaj choj impedance yog los sim qhov kev ncaj ncees ntawm lub sensor choj. Thaum kuaj, lub sensor yuav tsum raug txiav tawm ntawm lub thawv sib txuas thiab lwm yam khoom siv kuaj.

Qhov kev sim impedance input thiab output yog ntsuas tus nqi impedance ntawm lub input terminal thiab output terminal ntawm lub sensor nrog cov digital multimeter test leads, thiab piv tus nqi xeem nrog tus nqi ntawm daim ntawv pov thawj khoom; qhov kev lees paub ntawm kev sib txuas ntawm choj yog hais txog kev siv digital multimeter. Siv qhov impedance ntawm qhov kawg input thiab qhov kawg output, thiab ntsuas lawv ib zaug kom tau txais 4 pawg ntawm cov nqi impedance. Hauv lub sensor uas tau them rov qab tag nrho, qhov sib txawv ntawm plaub pawg ntawm cov nqi impedance yuav tsum tsis pub ntau dua 1Ω (tus nqi ntawm multimeter nrog qhov tseeb tsawg). yuav tsum tsis pub ntau dua 2Ω). 4. Sim cov zis sensor Txuas lub sensor rau lub zog fais fab tswj hwm sib cais, thiab siv lub zog excitation ntawm 10 ~ 15VDC. Txuas qhov kawg ntawm lub sensor rau millivoltmeter (lossis teeb tsa multimeter rau DC millivolt iav), thauj cov khoom thauj ntawm qhov kawg ntawm lub sensor raws li qhov kev teeb tsa thiab siv xwm txheej ntawm lub sensor, thiab saib qhov hloov pauv ntawm lub sensor.
