I-LMEC-19 Doppler Effect Experiment

Incazelo emfushane:

Ukulinganisa umphumela we-doppler kanye nesivinini somsindo.Izinga eliphezulu ukusetshenziswa enyuvesi.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izivivinyo
1. I-resonant frequency ye-ultrasonic transducer;
2. Ukulinganisa umphumela we-Doppler
3. Isivinini somsindo silinganiswa ngomphumela we-Doppler.
Imingcele yezobuchwepheshe eyinhloko

Incazelo	Imininingwane
Umthombo wesignali yamandla	Imvamisa yesignali: 20hz ~ 60khz Inani elincane lesinyathelo: 0.0011 hz Ukunemba kwemvamisa: ±20ppm Amandla okukhipha amandla: 1mv ~ 20vp-p Impedance 50 ohm
I-stepping motor intelligent motion control system	Ukunyakaza komfaniswano womugqa ongu-0.01 ~ 0.2m/s okulungiswayo, okulungile nokungalungile kokusebenza kwesikhombisi-ndlela.ngokuvikelwa okukhawulelwe: Umkhawulo we-Photoelectric, umkhawulo wokushintsha ukuhamba
I-Doppler frequency shift	0 kuya ku-± 10hz
Ukunemba kokulinganisa imvamisa yesistimu	±0.02hz
Ukulungiswa kokulinganisa imvamisa	0.01hz
I-double trace oscilloscope	Ukuzilungiselela
