long service life, low capacitance can make the circuit easy to match and good stability, small amplitude is shortcomings, display is small liquid level bubble, available liquid level is low.
Large black piece of pottery and porcelainultrasonic dispersion machineis characterized by fever, amplitude is larger and larger capacitance, fever is ambassador ceramic performance attenuation fast, short service life, capacitance is ambassador circuit not easy match, large amplitude is of advantages, hig
