Model: HNC-4SH-3828 Resonance frequency( KHz ): 28 Static capacitance( pF ): 4800 Resonance impedance(oum): 20 Size(D*H): 59*68 mm Power( W ): 60W Insulation impedance(2500V DC ): 100M Notes: Black chip(PZT4) "Ultrasonic transducer" is commonly known as "ultrasonic oscillator" or "ultrasonic oscillator." Used for ultrasonic cleaning industry, known as the "ultrasonic cleaning transducer." It is through the ultrasonic vibration-wave of the transducer occurring cavitations in the water and generates high-pressure vacuole to impact the cleaning materials, so as to achieve an excellent cleaning effect. *Features The ultrasonic transducer adopts the high steady piezoelectric ceramic chip and the design of front and back cover with best acoustic matching. The production produced has some features as follows: A. low resonance impedance B. high Q mechanical value C. high efficiency of mechanical and electrical transforming D. good hot staility E. low calorific capacity F. good consistency of frequency and static capacitance G. large amplitude, high vibration speed.
