- The built-in sensor of the ultrasonic transducer has the ability to emit ultrasonic waves to the outsideBefore making a related introduction, let's first introduce a commonly used field, such as reversing radar. When we buy a new car, the salesman will often introduce us to the relevant hardware in the car. Today, reversing radar has become the standard equipment of today's cars. When we are reversingUltrasonic Transducer information February 24, 2023
- How does ultrasonic transducer workThe sound that people can hear is due to the vibration of objects. Its frequency is within the range of 20HZ-20KHZ ultrasonic sensor. If it exceeds 20KHZ, it is called ultrasonic wave, and if it is lower than 20HZ, it is called infrasonic wave. Commonly used ultrasonic frequencies are tens of KHZ-teUltrasonic Transducer information February 23, 2023
- How to choose between photoelectric sensor and ultrasonic sensor in the technology difference?In recent years, there has been a growing demand from customers for machine solutions that handle the sensing of heterogeneous materials. Ultrasonic sensors use the time-of-flight principle, and other industrial technologies such as inductive and photoelectric sensors are blank. 1. How to choose phoUltrasonic Transducer information February 16, 2023
- What are the practical applications of ultrasonic transducers with circuits?Ultrasonic Sensors - Transducers that work on principles similar to sonar or radar and estimate target properties by interpretation are called ultrasonic sensors or transceivers. There are different types of sensors, which can be divided into active and passive ultrasonic transducers, which can be dUltrasonic Transducer information February 16, 2023
- Introduction to Piezoelectric Materials and Technical ParametersPiezoelectric materials are crystalline materials that generate a voltage between their two ends when pressure is applied. In 1880, French physicists P. Curie and J. Curie brothers discovered that when a heavy object is placed on a quartz crystal, some surfaces of the crystal will generate charges,Basics of Piezoelectric Ceramics February 14, 2023
- Properties and functions of piezo ceramic materialsMechanical properties Piezoceramic materials are materials with good rigidity and high hardness among engineering materials, and their hardness is mostly above 1500HV. Ceramics have high compressive strength, but low tensile strength, poor plasticity and toughness. thermal properties Ceramic materBasics of Piezoelectric Ceramics February 14, 2023
- Piezoelectric Polarization and Hysteresis LoopPolarization of piezoelectric ceramics Before the piezoelectric ceramic material is not polarized, the free electrons are arranged in disorder; after the polarization treatment, remanent polarization is generated along the polarization direction to become an anisotropic polycrystal, the free electroBasics of Piezoelectric Ceramics February 13, 2023
- Piezo Ceramic material introduceAbout the application of piezoelectric ceramic material is very much. Piezoelectric ceramic is a product of contemporary new technology, using a piezoelectric effect. Piezoelectric effect is a kind of information conversion device, mainly used in sound transducer, piezoelectric det, piezoelectric liBasics of Piezoelectric Ceramics August 08, 2017
- Piezoelectric properties of common piezoelectric ceramics and piezoelectric materialsPiezoelectric ceramics are artificial polycrystalline piezoelectric materials. The crystal grains inside the material have many spontaneously polarized electric domains, which have a certain polarization direction, so that there is an electric field. When there is no external electric field, the el
- Classification of piezoelectric materials of piezoceramicsOne is inorganic piezoelectric materials, which are divided into piezoelectric crystals and piezoelectric ceramics. Piezoelectric crystals generally refer to piezoelectric single crystals; piezoelectric ceramics generally refer to piezoelectric polycrystals.Piezoelectric ceramics refer to the polycrBasics of Piezoelectric Ceramics February 09, 2023
