Roj siab sensor 3083716 rau Dongfeng lub cev muaj zog excavator

Siab sensor yog ib qho cuab yeej nrog lub siab rhiab heev, uas ntsuas lub siab ntawm cov pa roj los yog kua los ntawm lub diaphragm ua los ntawm stainless hlau thiab silicon. Thaum siv lub siab sensor, qee qhov teeb meem yuav tshwm sim, xws li suab nrov. Dab tsi yog qhov ua rau lub suab nrov? Qhov no tuaj yeem yog vim qhov tsis sib xws ntawm cov khoom siv hluav taws xob sab hauv, lossis cov suab nrov uas tsim los ntawm cov khoom siv semiconductor. Lwm yam laj thawj yuav tau piav qhia hauv qab no.

Ua rau lub suab nrov hauv siab sensor

1. Lub suab nrov qis ntawm lub siab sensor feem ntau yog tshwm sim los ntawm qhov tsis sib xws ntawm cov khoom siv hluav taws xob sab hauv. Tshwj xeeb tshaj yog rau carbon zaj duab xis kuj, feem ntau muaj ntau me me hais nyob rau hauv cov ntaub ntawv carbon, thiab cov hais yog discontinuous. Nyob rau hauv tus txheej txheem ntawm tam sim no ntws, conductivity ntawm tus resistor yuav hloov, thiab tam sim no kuj yuav hloov, uas ua rau ib tug flash arc zoo li cov neeg pluag kev sib cuag.

2. Lub suab nrov ntawm cov khoom siv hluav taws xob tawg ua los ntawm cov khoom siv semiconductor feem ntau yog vim qhov kev hloov pauv ntawm qhov hluav taws xob ntawm thaj tsam barrier ntawm ob qho kawg ntawm lub semiconductor PN hlws ris, uas ua rau kev hloov pauv ntawm cov khoom siv hauv cheeb tsam no, yog li qhia txog kev cuam tshuam ntawm capacitance. Thaum qhov hluav taws xob ncaj qha txo qis, thaj tsam depletion ntawm electrons thiab qhov qhov dav dav, uas yog sib npaug rau qhov tso tawm capacitor.

3. Thaum rov qab voltage yog thov, lub depletion cheeb tsam hloov nyob rau hauv lub opposite kev taw qhia. Thaum qhov tam sim no ntws los ntawm cheeb tsam barrier, qhov kev hloov no yuav ua rau cov dej ntws tam sim no los ntawm cheeb tsam barrier hloov pauv me ntsis, yog li tsim cov suab nrov tam sim no. Feem ntau, nyob rau hauv cov khoom siv electromagnetic ntawm lub siab sensor Circuit Court board, yog tias muaj kev cuam tshuam, ntau lub Circuit Court boards muaj electromagnetic Cheebtsam xws li relays thiab coils. Nyob rau hauv tus txheej txheem ntawm tsis tu ncua tam sim no ntws, lub inductance ntawm lub kauj thiab cov faib capacitance ntawm lub plhaub radiate lub zog mus rau ib ncig. Lub zog yuav cuam tshuam nrog cov voj voog nyob ze.

4. Ua hauj lwm ntau zaus xws li relays thiab lwm yam khoom. Lub hwj chim-on thiab lub hwj chim-off yuav tsim instantaneous rov qab high voltage thiab instantaneous surge tam sim no. Qhov hluav taws xob tam sim no yuav muaj kev cuam tshuam zoo rau hauv Circuit Court, uas yuav cuam tshuam rau kev ua haujlwm ntawm lub zog ib txwm muaj. Circuit.
