The transducer of the ultrasonic cleaning machine is an energy converter. Its function is to convert the input electrical energy into mechanical energy (i.e. ultrasound) and then emit it. It only consumes a small portion of energy (less than 10%). Therefore, when using ultrasound transducers, the most important consideration is the matching of input and output, followed by mechanical installation and matching dimensions. There are many types of ultrasonic machines in the mall. It is necessary for customers to provide precise and reliable targets to ensure that the sensor products supplied by the company can match your machine well and fully function.

Due to the wide variety of sensors, this article only provides some sensor parameters.

(1) Resonant frequency: F， Company: kHz

This frequency refers to the frequency measured by transmission line methods such as frequency generators, millivolt meters, or impedance characteristic analyzers. It is generally referred to as small signal frequency. The opposite is the online frequency, which refers to the actual operating frequency measured by the user when connecting the sensor to the driving power supply through cables, no-load or loaded after power on. Due to the different matching circuits of users, the frequency displayed by different driving power sources of the same frequency converter is different and cannot be used as a basis for ordering.

(2) Sensor capacitance: ct， Company: pf

That is to say, the free capacitance of the sensor can be measured using a capacitance bridge or impedance characteristic analyzer with frequencies ranging from 400Hz to 1000Hz. Simply put, portable capacitance meters can also meet measurement requirements.

Due to different processing methods and requirements, transducers can be roughly divided into continuous processing (such as lace machines, CD machines, zipper machines, metal welding machines, etc.) and pulse processing (such as plastic welding machines). Different homework methods have different requirements for sensors. Generally speaking, there are almost no interruptions in continuous operation, but the operating current is not very high. Pulse operation is intermittent with interruptions, but the instantaneous current is high. On average, both states have high levels of power.

Manufacturers may have different requirements regarding the rated power of machines for different purposes and applications. In other words, the nominal power of the same sensor used on different machines may vary. To avoid ambiguity, customers should specify the structure of the transducer, such as cylindrical shape, inverted horn, and the diameter and quantity of piezoelectric ceramic plates.

Mainly includes speaker materials, surface treatment, and shape. Use threaded connections between the sensor and the horn, and between the horn and the mold. Confirm the diameter, thickness, quantity, and position of the notches or holes on the horn flange.
