Yuav Ua Li Cas Tuning Fork Densiometer Ua Haujlwm

Lub suab rab rawg densitometer sensor yog tsim los raws li lub hauv paus ntsiab lus ntawm kev co, qhov kev vibration no zoo ib yam li lub suab diav rawg ntawm ob tug hniav, diav rawg lub cev los ntawm piezoelectric siv lead ua nyob rau hauv lub hauv paus ntawm cov hniav kev co, kev co zaus yog kuaj los ntawm lwm piezoelectric siv lead ua. , los ntawm kev hloov pauv theem thiab kev ua kom muaj zog, lub cev diav rawg yog stabilized ntawm qhov inherent resonance zaus. Thaum qhov nruab nrab ntws los ntawm rab rawg lub cev, qhov kev hloov ntawm lub resonance zaus yog tshwm sim los ntawm kev hloov ntawm nruab nrab loj.

Rationale: Lub suab diav rawg densitometer siv cov kev sib raug zoo ntawm qhov ntom ntawm cov khoom siv thiab nws cov nyhuv ntawm qhov ceev ntawm acoustic propagation.Thaum suab nthwv dej propagate rau hauv cov ntaub ntawv uas sib txawv ntom, lawv propagation ceev yuav hloov.

Vibrating suab diav rawg: Lub suab diav rawg siv nyob rau hauv lub suab diav rawg densitometer yog ua los ntawm ib tug slender hlau bar, zoo li tus inverted "U" lo lus.Lub suab diav rawg yuav vibrate los ntawm electromagnetic excitation los yog piezoelectric excitation.

Excitation thiab nrhiav kom tau: lub suab diav rawg yog zoo siab los ntawm lub electromagnetic los yog piezoelectric ntaus ntawv ua rau nws vibrate.Tam sim no, lub built-in sensor los yog detector soj ntsuam lub vibration xeev ntawm lub suab diav rawg.

Kev ntsuas ceev: Thaum lub vibration nthwv dej ntawm lub suab rab rawg propagated rau hauv cov khoom yuav tsum tau ntsuas, qhov ceev ntawm cov khoom yuav cuam tshuam rau propagation ceev ntawm lub suab nthwv dej.Thaum lub suab nthwv dej kis mus rau qhov teeb meem nrog ntau ntom, nws propagation ceev yuav hloov, yog li muaj kev cuam tshuam rau kev vibration ntawm lub suab diav rawg.

Resonance zaus ntsuas: qhov ceev ntawm cov khoom yog txiav txim los ntawm kev ntsuas lub resonance zaus ntawm lub suab diav rawg.Cov khoom uas muaj siab dua yuav txo cov propagation ceev ntawm lub suab yoj, uas txo cov resonance zaus ntawm lub suab diav rawg, thiab propagation ceev. thiab resonance zaus ntawm lub suab diav rawg.

Kev suav ceev: Raws li kev ntsuas yav dhau los thiab kev sim cov ntaub ntawv, qhov ntsuas resonance zaus tau muab piv nrog qhov sib thooj los txiav txim siab qhov ntom ntawm cov khoom yuav ntsuas.
