Ultrasonic transducer sensors are widely used to measure wind speed and wind direction. The design of the front-end circuit is directly related to the performance of the system. In order to achieve a stable driving effect, the driving circuit adopts a low-voltage driving method. In order to receive

In industry, the typical applications of ultrasonic are non-destructive testing of metals and ultrasonic thickness measurement. In the past, many technologies were hindered because they were unable to detect the inside of the object's tissues. The emergence of ultrasonic sensing technology has chang

In daily production and life, ultrasonic distance sensors are mainly used in car reversing radar, automatic obstacle avoidance walking of robots, construction sites and some industrial sites, such as liquid level, well depth, pipeline length, etc., which require automatic non-contact ranging. There

introductionAt present, one of the difficult problems faced in the extraction of crude oil in oil fields is the online measurement of the extracted crude oil. The main reason is that the composition of crude oil is very complex. The crude oil contains oil, water, gas and other impurities. It is a mu

Ultrasonic level gauge is a non-contact liquid level measuring instrument. In actual work, the ultrasonic probe emits a pulse wave. After reaching the surface of the liquid level, it returns to be received by the sensor. The measured level gauge is calculated by the time difference between sound wav

Piezoelectric transducers are ultrasonic sensors made by using the piezoelectric effect produced by certain dielectrics. The so-called piezoelectric effect refers to the phenomenon that when certain dielectrics undergo deformation (including bending and stretching deformation) due to the polarizatio

Question 1: Under the excitation of the piezoelectric ceramic driving power, the maximum drive displacement drops from 45um to 33um. What is the reason?We need to explain in different situations. If there is no ignition, it means there is no breakdown or short circuit, and there is displacement outp

basic introduction:Ultrasonic transducers sensor are developed by using the characteristics of ultrasound. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, which can become rays and propagate directionally. Ultrasonic waves ha

Application of Ultrasonic Level Gauge in Sewage Treatment Plant

Indoor positioning is an application that has been proposed in recent years. How to use ultrasonic transducers for indoor positioning? Take a recent university experiment with the DYA-21-G ultrasonic transducer as an example, here is a brief introduction.

Using the flexural vibration of the conventional piezoelectric bimorph element vibrator, it is impossible to achieve this purpose when the frequency of ultrasonic module distance measuring transducer is higher than 70kHz. Therefore,by high frequency detection, piezoelectric ceramics with vertical th

With the further development of information technology in the chemical, petroleum and hydropower sectors, ultrasonic transducer sensor are widely used in oil level, water level and other liquid level measurement. Utilizing the characteristics of ultrasonic, we know that it can also be made into an u

An extension of the ultrasonic sensor is a good supplement to the existing detection system of mobile robots. It has been fully demonstrated in experimental applications, and it has certain practicality in obstacle detection and robot pose adjustment. However, this method needs to be further improve

Analysis of interference factors and measures are takenOne of the biggest disadvantages of using multiple sensors to transmit ultrasonic waves in parallel is that the interference is more serious, especially the signal interference between the sensors. The main factors that cause interference are as
