In the past 20 years, piezoelectric ceramics transducers have developed rapidly at home and abroad. Due to its simple production, low cost and good stability, it has been widely used in the fields of electronics, light, heat and acoustics, and has a broad development. prospect. Ultrasonic transducer

Design of single chip circuit:Because the microcontroller integrates the watchdog, CCU comparison unit, analog comparator, A/D converter and other components, it simplifies the circuit design and saves costs.The MCU is powered by +3V and is supplied by the regulator chip HT7130. It uses a 2.4576MHz

A pulse (emission wave) generated by the high-frequency pulse generator is applied to the ultrasonic sensor probe to excite the piezoelectric crystal to oscillate to generate ultrasonic waves. Ultrasonic waves propagate to the inside of the workpiece at a certain speed. A part of the ultrasonic wave

Ultrasound refers to mechanical waves with a frequency higher than 20 kHz. In order to use ultrasonic waves as a detecting means, it is necessary to generate ultrasonic waves and receiving ultrasonic waves. The device that performs this function is an ultrasonic sensor, which is customarily called a

Ultrasonic ranging transducer at low SNR and low sampling rates based on cross-correlation function. The specific method is as follows the ultrasonic signal sent by the transmitter is used as a reference signal, and the output of the receiver is immediately sampled at the end of each transmission of

The ultrasonic distance measuring transducer with double crystal oscillator is a bimorph ceramic that is bonded together and has opposite polarization directions.The working principle of the sheet is to apply an alternating electric field of opposite polarity to the upper and lower ceramic sheets in

Ultrasonic transducers are essentially a class of electromechanical energy conversion devices, which can be divided into piezoelectric, electromagnetic and magnetostrictive types according to their working principles. At present, common ultrasonic transducers are generally piezoelectric, which works

At present, foreign big car companies have invested a lot of resources to develop advanced anti-collision and safety warning systems for advanced cars with GPS, but the excessive cost limits its application in ordinary cars. To this end, greatly reducing the cost of the car's active anti-collision a

Ultrasonic transducers, what kind of pulses do they need to generate or obtain ultrasound? How to confirm the resonance frequency ?About ultrasonic transducer, the pulse required is a high-frequency pulse signal, and is determined by its driving frequency. As for the resonant frequency of the trans

At present, there are two types of ultrasonic transducer sensor, one is an in-vehicle integrated probe, other is an integrated transmitting and receiving probe . The other is a separating design for sending and receiving. The basic principle of its implementation is that the transmitting probe emits

Principle and application of ultrasonic position sensorUltrasound waves is a general term for mechanical waves whose frequency exceeds the human 's auditory frequency limit (approximately 20 kHz). Ultrasonic waves are generated by vibration transducer under the excitation of voltage. Distance measur

The factors to affect the ultrasonic distance transducer

Combinated dual-crystal probe will send receiving mode in the detection of work , the two wafers were launched and receiving ultrasonic transducers for distance, so that the sound of the ultrasonic transducer datasheet

The basic ultrasonic transducer is commonly known as flat probe or straight probe, its structure includes many functions,like piezoelectric chip, the function of protective film and fast absorption
