Ultrasonic transducer, also known as ultrasonic probe, is a key component of the ultrasonic level meter, and it is not too much to say that it is the "heart" of the ultrasonic level meter. The ultrasonic transducer converts high-frequency high-voltage power into high-frequency mechanical vibration, and the maximum power output can reach several kilowatts, so the stability and power output of the ultrasonic transducer for cleaning plays a very important role in the performance of the ultrasonic level transmitter. It can be said that the ultrasonic transducer is the most valuable part of the ultrasonic level meter, and its quality directly affects the quality of the whole meter. Since the ultrasonic transducer is so important to the ultrasonic level meter, how to detect the good or bad of the ultrasonic transducer?

To detect the good or bad of the ultrasonic transducer, in general, the following detection methods are more common: 

　　1, from the process design and use of materials to identify: because the quality of the materials selected has a direct impact on the quality of the product, so to determine the quality of the product and whether the process design is reasonable, should be based on the materials selected to determine. The same specification of the material, if the origin is not the same, the quality difference will be larger. If the quality of the material is poor, it is difficult to use the best technology to make a better quality product. To do a good job on the process design and the use of material identification, there is a prerequisite, that is, the ultrasonic sensors material to be more familiar and understanding.

　　2, from the production process and product appearance to identify: this is because on the one hand, the design and production process has a direct impact on the quality of the product, the other side of the production process and product appearance is good or bad, is also an important basis for determining whether the manufacturer attaches importance to product quality. Although not absolute, but in general, the process and the appearance of good product quality is not bad to where.

　　3, parameter detection: in order not to affect the normal use, should test the parameters of the ultrasonic level sensor wholesale and electrical box parameters match.

4, on the machine test.

　　(1) stability test: also known as simulated aging test, specifically bring the rated load of the equipment, test the power output stability of the electrical box and transducer.

　　(2) overload operation test: through the test, test the stability of product quality and service life. This test only needs to bring the rated load continuous uninterrupted operation for 8 hours.

　　(3) Power output test: This test can detect whether the transducer and the electric box are matched, and at the same time can reflect the size of the electric box and the load power output of the transducer.
