- Ultrasonic metal flaw detection-ultrasonic transducerMetal ultrasonic flaw detector is a portable industrial nondestructive testing equipment, it can quickly, easily, without damage, accurate inside the workpiece a variety of defects (including longitudinal cracks, transverse cracks, loose, pores, slag, etc.) detection, positioning , Assessment and di
- Ultrasonic Acoustic Transducer IndustrialThe underwater acoustic transducer is operated by the piezoelectric effect of the crystal (quartz or potassium tartrate) piezoelectric ceramics (barium titanate and lead zirconate titanate) or the magnetostrictive effect of iron-nickel alloy. The so-called piezoelectric effect is to cut the crystal

- Piezoelectric Ceramics ParameterThe piezoelectric properties of ceramics were first discovered on barium titanate, but due to the difficulty of sintering pure barium titanate ceramics, and the Curie point (120 ℃), near room temperature (about 5 ℃) phase transition occurred, even if Change its doping characteristics, the piezoelect
- Piezoelectric gyroscopePiezoelectric gyroscope is a product of computer popularization and sensor technology development. Typical features are: measuring probe circuit is simple and reliable, only accurate to collect the sensor response value (electrical signal), communication, by the ground computer memory, storage data,
- Knock Sensor-piezoelectric ceramic sensorKnock sensor installed in the middle of the engine cylinder to four-cylinder machine as an example installed in the 2-cylinder and 3-cylinder, or 1, 2 cylinder in the middle of a 3,4-cylinder middle one. Its role is used to determine the engine jitter, when the engine is used to adjust the ignition
- The applications of the ultrasonic imaging technologyUltrasound imaging is the use of ultrasonic sound beam scanning the human body, through the reflection of the signal reception, processing, in order to obtain the image of the body organs. Commonly used ultrasound equipment has a variety of: A type (amplitude modulation type) is the level of the amp
- ultrasound imaging: the application of the ultrasonic transducerUltrasound imagingUltrasound medicine is a combination of acoustics, medicine, optics and electronics. Where the study of higher than the audible frequency of acoustic technology, in the field of medical applications that is the ultrasound medicine. Including ultrasound diagnosis, ultrasound therap
- Piezoelectric Ceramic Sensor-Knock SensorKnock sensor is used to detect the engine engine block deflagration strength. Once the deflagration occurs, the ECU is instructed to delay the ignition and turn to the closed timing control of the ignition timing in order to adjust the ignition timing.Installed in the cylinder on the specific detect
- Progress of Underwater Acoustic TransducerProgress of Underwater Acoustic TransducerSince the 1960s, in order to achieve the sonar remote detection, the development of a number of new materials, structural vibration and energy conversion mechanism; the development of the work in low-frequency, broadband, high power and deep water transmitte
