YP-3535-4D 35 Khz ultrasonic transducer 1.High Efficiency: of high mechanical factor. High transfer efficiency is obtained when working in resonance frequency. 2.Big amplitude: designed and chosen by computer, high rate in oscillation speed and big amplitude in front operculum 3.Big Power: under the function of the pre-stressed force screw rod, the piezoelectricity ceramics can work freely in the highest level of power. 4.In good heat resistance: of small resonance impedance, less heat produced, can be used in a wide range of temperature with long life and high reliability.
