Ultrasonic Transducer Sensor

Ultrasonic transducer sensor is a power ultrasonic cleaning transducer that converts electrical energy into mechanical vibration. Ultrasonic cleaning transducer is mainly composed of piezoelectric ceramics, electrodes, front cover plate, rear cover plate, fastening bolt and insulation sleeve.

The ultrasonic cleaning transducer is installed on the container (to ensure the effectiveness of ultrasonic transmission, the ultrasonic transducer must be installed on the surface of the metal container). When powered on, the entire container acts as the negative electrode. At this time, the transducer and container form a circuit, which serves as grounding through the entire equipment. The powered circuit and equipment can achieve good grounding and other safety requirements as required, and can be used relatively safely.

Product features:

1.High performance: high mechanical Q value, electro-acoustic conversion efficiency of more than 90%.

2.Large amplitude: when compared with the magnetostrictive transducer, it's amplitude increased by more than 50%,

3.Heat resistance: the use of materials which has good heat resistance, low resonant impedance and small heat.

4.Strong structure: standard steel bolt fastening that has high reliability.

FAQ:

Q：What about 40khz 50W/60W/100W ultrasonic transducer oscillator

The 40khz ultrasonic transducer oscillator is usually suitable for a power of 50W or 60W, and 100W is only used in special circumstances because of its high cost. The 40khz ultrasonic transducer uses two positive and negative electrode plates, two piezoelectric ceramic plates with a diameter of 35 or 38.1; The materials of piezoelectric ceramic plates for 40khz ultrasonic transducers are divided into black PZT-4 material and yellow PZT-8 material. The black plate cleaning force is strong, and the yellow plate output is stable. The capacitance value of the 40khz ultrasonic transducer oscillator is between 1600 and 1800, the impedance is between 10 and 20, and the frequency is between positive and negative 0.3 khz. The capacitance value of the ultrasonic cleaning transducer is low, the impedance is small, and it is easy to match with the ultrasonic generator. Moreover, the ultrasonic transducer has low heat generation, strong ultrasonic output amplitude, and good industrial cleaning effect. The 40khz ultrasonic transducer oscillator is mainly used in household ultrasonic dishwashers, ultrasonic vegetable washers, industrial ultrasonic cleaning equipment, ultrasonic vibration plate boxes, digital ultrasonic cleaning machines, large-scale ultrasonic cleaning systems, and so on.

Q：What is the Installation process of ultrasonic transducer sensor？

When to make a high quality ultrasonic cleaning machine, it‘s not only the selection of high quality ultrasonic generator, high quality ultrasonic transducer and high quality steel ultrasonic tank, but also must consider many aspects: such as ultrasonic transducer paste, steel plate is flat, thickness is enough.

1. Steel plate generally uses 304# or 316# 1mm to 2.5mm thick steel plate to ensure that the ultrasonic tank plate is smooth and clean.

2. When to screw welding of the ultrasonic cleaning transducer at the bottom of the tank, the screw must be welded firmly and must be vertical with the bottom of the tank

3. Gently polish the area around the screw with sandpaper, and then clean it with alcohol.

4. Glue proportioned, to mix the glue repeatedly.

5. Evenly apply the glue to the bottom of the transducer

6. Repeatedly rotate the transducer and tank surface several times, so that the air and excess glue between the transducer bottom and the cylinder bottom contact surface are extruded out, and the thinner the glue is, the better!

7. Tighten and fix the transducer with a wrench, so that the bonded transducer can not shift. But not too hard, so as not to screw broken.

8. Wiring: all the positive electrode of the transducer with 2.5 flat wire welding, all the negative electrode of the transducer with the same wire welding

9. Generally after 6-48 hours（according to the specified time of the glue), power on after the glue is fully fixed
