High Frequency inoenderana 1khz Ultrasonic Impedance Alyzer

Yakakwira frequency inowirirana ultrasonic isina kukodzera kuongorora kune Ultrasound transducers

Ndoita seiKuongorora mashandiro eiyo Ultrasonic transducer?

Kuti uongorore kuitwa kwekuita kweiyo ultrasonic vibration system, inodikanwa kuongorora kubva pane zviviri zvikamu: paramita uye kubvumirana curves:

1) paramita:

Iyo isingacheki inoongorora inogona kuongorora mashandiro emhando dzakasiyana-siyana senge piezoelectric ceramic masheets Kuongororwa kweiyo Ultrasonic midziyo yekushandisa neyakakundwa anoongorora, iyo inonyanya kukosha parameter ndeye inotevera:

FS: Iyo yekudyidzana yekukwira frequency, kureva kuti iyo yekushandisa frequency yeiyo vibration system, inofanira kunge iri pedyo neiyo kukosha kwekutarisirwa sezvinobvira mukugadzirwa uye kunofanirwa kuenderana neyekupa simba rekushandisa.

Kumuchina wekuchenesa, wepamusoro-soro raidonhedza nguva yekuwirirana kweVibrator, zviri nani.

Kune vepurasitiki vepurasitiki kana chishandiso chekupedzisira, kana runyanga kana ruvara rwekugadzira zvisina musoro, iyo yekukanda frequency yeVibrator ichatsauka kubva pane yekushanda.

R1: Dynamic Kuramba, kupokana kwenhare dzevatevedzeri vePizoelectric Vibrators, zvidiki zviri nani pasi pemamiriro ezvinhu akafanana. Yekuchenesa kana kufambisa vibrators, kazhinji iri pakati5 ω and ω ω Kana zvakakura kwazvo, vibrator kana vibrator kana yekubvunda system ichave nematambudziko, yakadai sedunhu risingakwanisi kugona kana kushandurwa kwakaderera, uye hupenyu hupfupi hwemberi.

QM: Mechanical mhando Factor, yakatemwa neiyo inofambidzana curve nzira, QM = FS / (F2 - F1), iyo hIKher the qm, iri nani, nekuti yakakwira qm, yakakwira iyo vibrator yekubudirira; Asi QM inofanirwa kuenderana neSimba Simba, iyo QM kukosha yakanyanya kukwirisa simba rinowanikwa.

Kuti uchenese vibrator, yakakwira iyo QM kukosha, zvirinani. Kazhinji, iyo QM yeVibrator Vibrator vanofanirwa kunge vari pakati pe500 uye 1000. Kana zvakanyanyisa kuderera, iyo vibrator kugona kwakaderera. Kana zvakanyanyisa, iyo simba risina simba harigone kufananidzwa.

Zvekusimbisa kwelting Kana zvakanyanyisa kuderera, kugona kwehunyanzvi kwakaderera, asi hakugone kuve kwakanyanya, nekuti iyo Bandwidth yakamanikana

CT: Mahara emahara, iyo capacitance kukosha kweiyo piezoelectric mudziyo pa1 KHz. Ukoshi uhwu hunoenderana neicho kukosha kuyerwa neiyo dijitital capacitance mita. Iyi kukosha inobvisa iyo Dynamic capacitor c1 kuti uwane iyo chaiyo static capacitance c0, c0 = ct - c1. Paunenge uchishandisa, Balance C0 neKufarira.

Mudunhu redunhu remushini rekuwachisa kana ultrasonic yekugadzirisa muchina, nenzira yakakodzera c0 inogona kuwedzera simba rezvinhu zvekuwanikwa kwesimba. Kune nzira mbiri dzekushandisa iyo Inductor Balance, kufanana tuning uye kutevedzana tuning.

FP: Anti - Resonance Frequency, iyo yekukwira yekufambisa kwebazi rakafanana rePiezoelectric vibrator vibrator vibrator. Panguva ino yekufambisa, iyo isingakunde zmax yeiyo piezoelectric vibrator ndiyo yakakura. Kana iyo anti - Resonant aregedza Zmax yakaderera, vibrator ine dambudziko.

2) mifananidzo

Iyo yekukundwa inoongorora marudzi mashanu ehurongwa hwekurongedza hunhu, uye iyo logarithmic yemunhu diagram ine kukosha kwakakosha kwekuonekwa kwe piezoelectric zvishandiso. Kuita kwehunyanzvi hwekuita kwe piezoelectric vibrator kana system yekubvunda inogona kutongwa zvakananga neiyo logarithmic girafu, iyo inonyatsojekesa uye inoshanda.

Mumamiriro ezvinhu akajairwa, iyo yekubvuma denderedzwa uye iyo curve curve inoratidzwa mune inotevera nhamba.

Kuita:

Iyo yekubvuma denderedzwa idenderedzwa imwe chete, uye iyo logarithmic graph ine chete maviri mashoma uye huwandu hwakanyanya:
