Chapter 3 Ultrasonic Waves Method for Interface Pressure
Detection of Ultrasonic Waves. Home > Detection of Ultrasonic Waves . 1. Piezoelectric Detector. Piezoelectric effect can also be used to detect ultrasonics. If ultrasonics comprising of compressions and rarefactions are allowed to fall upon a quartz crystal a certain potential difference is developed across the faces which after amplification by a value amplifier can be used to detect... Ultrasonic piezo transducers ensure efficient production of particularly homogeneous aerosols with ultrasonic vibrations above 100 kHz. Piezo Micropumps Piezoelectric micropumps are used in laboratory technology, medical technology, biotechnology, chemical analytics and process engineering.
Production of Homogeneous Aerosols with Ultrasonic Piezo
Many ultrasonic devices, among which are surface and bulk acoustic wave devices and ultrasonic transducers, are based on multilayers of heterogeneous materials, i.e., piezoelectrics, dielectrics, metals, and conducting or insulating fluids.... Ultrasonic nondestructive testing introduces high frequency sound waves into a test object to obtain information about the object without altering or damaging it in any way.

Introduction to Ultrasonics. Properties of Ultrasonic waves. Ultrasonic Production- Magnetostriction Method. Piezo Electric Method. Detection Methods
- Ultrasonic waves can be created by periodically exciting so-called piezoelectric material with ac voltage. The so-called piezo element is the core of an ultrasonic head. During ultrasound testing, the ultrasound created in the test head has to be transferred to the test material.
- The device generates probing ultrasonic waves (one longitudinal and two transverse, polarized in mutually perpendicular directions) by piezoelectric transducers (PETs) serving as piezo-actuators. The reflected elastic waves excited in the material of the controlled object are also received by the same PETs via converting mechanical vibrations to a potential difference.
- (5) Ultrasonic cutting and machining(5) Ultrasonic cutting and machining Ultrasonic waves are used for cutting and machining. 31 (6) Ultrasonic cleaning It is the most cheap technique employed for cleaning various parts of the machine, electronic assembles, armatures, watches etc., which cannot be easily cleaned by other methods.
- PRODUCTION OF ULTRASONIC WAVE (1) Magneto-striction generator or oscillator (2) Piezo-electric generator or oscillator . MAGNETO-STRICTION GENERATOR Principle: Magnetostriction effect When a ferromagnetic rod like iron or nickel is placed in an alternating magnetic field parallel to its length, the rod experiences a small change in its length. The change in length (increase or decrease
