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

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

Ultrasonic sensors are widely used in robot obstacle avoidance systems. Based on the ultrasonic ranging principle, a parallel ranging system is designed. The hardware composition and software realization method of the system are introduced. Aiming at the phenomenon that multi-sensor parallel ranging

For many years, ultrasonic sensors have been widely used in passenger cars. For example, ultrasonic parking system can help vehicles detect surrounding objects when it is parking at low speeds. In addition, kick-opening the trunk and intrusion detection alarm are two emerging applications of ultraso

Robot autonomous positioning and navigation of ultrasonic level sensor is simple, but it needs to be based on the combination of map data + algorithm to achieve true automatic automatic navigation; robot navigation can be divided into three parts, including positioning, mapping and motion control. W

As the name implies, the aircraft model is a recyclable model made to imitate the shape of a spacecraft. It belongs to the aerospace model. In the competition rules formulated by the International Aviation Federation, it is clearly stipulated that the aircraft model is heavier than air and has a siz

Ultrasonic sensor is a sensor that can measure distance and position by sending and receiving ultrasonic waves. Since the sunroofs of automobiles are almost transparent, various sensors based on optical principles cannot measure. The ultrasonic sensor can send out ultrasonic waves and receive echoes

Industrial ultrasonic sensor has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, which can become rays and propagate directionally, long range ultrasonic sensor has a great ability to penetrate liquids and solids, especially in soli
