Yuav ua li cas yuav ua rau ib tug magnetostrictive transducer nrog koj ob txhais tes: qhov kev piav qhia ntawm lub tswvyim thiab cov tswv yim

Yuav kom tsim ultrasonic magnetostrictive transducers yog siv tshwj xeeb. Qhov loj ntaus ntawv tsis txog kuj thiab conductivity. Tsis tas li ntawd coj mus rau hauv tus account lub permissible nqi ntawm cov zaus. Los ntawm kev siv ntawm cov ntaus ntawv tej zaum yuav txawv. Nws yuav tsum tau muab sau tseg tias cov qauv uas siv kev koom nyob rau hauv fishfinders. Yuav kom nkag siab txog cov dab, nws yog ib qho tseem ceeb los xav txog lawv cov tswvyim.

tsav ntaus ntawv

Standard magnetostrictive ultrasonic transducer muaj ib tug sawv thiab ib co ntawm cov terminals. Magnet ncaj qha nkag mus rau lub condenser. Nyob rau hauv lub qaum kev ib lub ntaus ntawv muaj ib tug winding. Tom qab ntawm dab feem ntau teem lub clamping nplhaib. Cov magnet yog tsim tsuas neodymium hom. Thaum lub sab saum toj ntawm tus qauv yog tus pas nrig. Rau nws kho nplhaib yog thov.

nplhaib kev hloov kho

Annular pab kiag li lawm khiav lag luam ntawm los ntawm 4 microns conductivity. Muaj ntau cov qauv no yog ua los nrog luv luv kev muag zaub. Nws yuav tsum raug sau tseg hais tias muaj kev hloov kho nyob rau hauv lub teb condensers. Yuav kom sib sau ua ke ib magnetostrictive transducer nrog koj ob txhais tes, siv ib tug solenoid kauj. Yog li ntawd nws yog ib qho tseem ceeb los mus teev terminals ntawm tsawg Harbor voltage. Ferrite pas nrig tsim nyog los xaiv ib tug me me txoj kab uas hla. Cov clamping nplhaib yog muab tso rau lub xeem.

Ntaus nrog kwj

Ua ib tug magnetostrictive transducer nrog koj txhais tes yog heev yooj yim. Feem ntau tua thiaj tom NQHAJ. Tom ntej no, nws yog ib qho tseem ceeb mus txiav txoj kev muag zaub. Ua li no, koj yuav siv tau ib tug hlau disc. Kws txawj hais tias txoj kev muag zaub txoj kab uas hla yuav tsum tsis muaj ntau tshaj li 3.5 cm. Terminals rau cov ntaus ntawv xaiv nyob rau hauv 20 V. Thaum lub sab saum toj ntawm lub nplhaib qauv tsau. Yog hais tias tsim nyog, koj muaj peev xwm poob rau daim kab xev. cov kuj muaj nqis nyob rau lub emitters ntawm no hom yog nyob ib ncig ntawm 30 ohms. Lawv ua hauj lwm nrog conductivity ntawm tsawg kawg yog 5 microns. Lub winding nyob rau hauv cov ntaub ntawv no tsis yog yuav tsum tau.

Model nrog ob winding

Devices nrog dual-chev ua los ntawm txawv diameters. Lub conductivity ntawm cov qauv ntawm ib ncig 4 microns. Feem ntau cov pab kiag li lawm muaj ib tug siab yam ntxwv impedance. Mus ua ib tug magnetostrictive transducer nrog lawv tus kheej txhais tes, siv xwb ib tug steel kev muag zaub. Lub insulator nyob rau hauv cov ntaub ntawv no tsis yog yuav tsum tau. Ferrite pas nrig yuav muab ntsia tau rau ntawm lub ncoo. Tshwj xeeb pom zoo kom ua ntej los npaj lub O-nplhaib. Nws yuav tsum tau muab sau tseg tias cov emitter ke yuav tsum tau teb yam capacitor. Lub kuj ntawm lub tswv yim ntawm cov qauv yuav tsum tsis txhob ntau tshaj 20 ohms. Lub windings yog muab tso rau ib sab mus rau lub pas.

Dab rau lub hauv paus ntawm lub Reflector

Dab ntawm no hom yog distinguished siab conductivity. Ua hauj lwm qauv ntawm ib tug voltage ntawm 35 V. Muaj ntau lub pab kiag li lawm yog nruab nrog teb condensers. Ua ib tug magnetostrictive transducer nrog lawv txhais tes yog theej problematic. Ua ntej peb yuav tsum khaws cov pas nrig ntawm me me txoj kab uas hla.
