Dual-frequency multifunctional ultrasonic transducer

Abstract

The invention discloses a dual-frequency multifunctional ultrasonic transducer. A fixed bolt sequentially penetrates through a transducer pressure plate, a first lug plate, a first cleaning transduction sheet, a second lug plate, a second cleaning transduction sheet, a transducer vibration block and a measurement transduction sheet; the tail end of the fixed bolt is fixedly connected with the measurement transduction sheet, the first lug plate and the second lug plate are connected with a power supply, the first cleaning transduction sheet and the second cleaning transduction sheet jointly generate ultrasonic waves with frequency of 20-3000K; and the measurement transduction sheet generates ultrasonic waves with the frequency of 800K-5M for measurement, and the frequencies of the two transduction sheets alternatively work. The invention has the advantage that liquid measurement devices such as an ultrasonic heat meter, an ultrasonic water meter and the like can achieve actual cleaning without disassembly by using the dual-frequency multifunctional ultrasonic transducer provided by the invention.

Description

Technical field [0001] The invention relates to an energy conversion device for measurement industries such as an ultrasonic heat meter, an ultrasonic water meter, and ultrasonic liquid measurement. Background technique [0002] The existing ultrasonic liquid metering equipment will generate dirt after one or two years of operation, which will affect the measurement accuracy. The existing solution is to remove the ultrasonic liquid metering equipment for cleaning, and then re-calibrate it before installing it. This method requires a lot of money, time and manpower to clean once, and the time required to disassemble and assemble a watch needs at least one hour. The maintenance of the metering industry is difficult and expensive. At present, all ultrasonic transducers used in ultrasonic heat meters, ultrasonic water meters, ultrasonic liquid metering and other industries use a single fixed frequency, and it is difficult for such ultrasonic transducers to give full play to the ...

[0002] The existing ultrasonic liquid metering equipment will generate dirt after one or two years of operation, which will affect the measurement accuracy. The existing solution is to remove the ultrasonic liquid metering equipment for cleaning, and then re-calibrate it before installing it. This method needs to invest a lot of money, time and manpower to clean once, and it takes at least one hour to disassemble and assemble a watch. The maintenance of the measurement industry is difficult and expensive.

At present, all ultrasonic transducers used in ultrasonic heat meters, ultrasonic water meters, ultrasonic liquid metering and other industries use a single fixed frequency. It is difficult for such ultrasonic transducers to give full play to the versatility of ultrasonic waves.
