  • Ultrasonic sensors
    Ultrasonic sensors can measure distance without contact. Typical ultrasonic sensors emit highfrequency sound waves that are reflected by the target. A target in the path of the sound wave reflects the sound back to the sensor where it is detected, triggering the sensor output. Special programmable
  • Implementing Ultrasonic Ranging
    Object ranging is essential in many types of systems. One of the most popular ranging techniques is ultrasonic ranging. Ultrasonic ranging is used in a wide variety of applications including: ? Autofocus cameras ? Motion detection ? Robotics guidance ? Proximity sensing ? Object ranging
  • Ultrasonic Transducers Technical Notes
    The Technical Notes section is designed to provide a brief overview of the ultrasonic principles important to transducer application and design. The Technical Notes are organized in the following sections.
  • Ultrasonic Sensor Applications
    The key to ultrasonic liquid detection is to keep the beam perpendicular to the liquid level and away from structures like tank walls, internal ladders, and impellers.
  • Introduction to Ultrasonic Cleaning
    Ultrasonic energy exists in a liquid as alternate rarefac­tions and compressions of the liquid. During rarefaction, small vacuum cavities are formed which collapse, or implode, during compression. This continuing rapid process, called cavitation, is responsible for the scrubbing effect which
  • Intro to Ultrasonic Phased Array
    Many people are familiar with the medical applications of ultrasonic imaging, in which high frequency sound waves are used to create highly detailed cross-sectional pictures of internal organs. Medical sonograms are commonly made with specialized multi-element transducers known as phased arrays
  • The Basic Principle Of Ultrasonic Assembly
    Ultrasonic plastics assembly is the joining or reforming of thermoplastics through the use of heat generated from high-frequency mechanical motion. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. That mechanical motion, along with applied
  • Application of Ultrasonic Cleaning
    Many articles exist describing "how ultrasonic cleaning works". The goal of this article is to help develop an understanding of the various components that ensure good ultrasonic cleaning. First, establish a cleaning need, along with a determination as to how to measure the level of cleanliness
  • Ultrasonic Processing of Fabric and Film
    Fabrics and films used in the nonwoven, medical, filtration, textile and packaging industries can be processed using ultrasonic energy. Several of the common techniques applied are ultrasonic rotary/continuous bonding, ultrasonic slitting, plunge and traversing. Ultrasonic bonding assembles two
  • Ultrasonic Staking Configurations
    Ultrasonic staking, or riveting, is an assembly procedure used to join dissimilar materials, usually plastic to metal or dissimilar plastics. A hole in the metal part receives the plastic rivet, or stud, and a specially contoured horn contacts the stud. The stud melts and reforms to create
  • Ultrasonic Material Analysis
    Ultrasonic nondestructive testing is a versatile technique that can be applied to a wide variety of material analysis applications. While ultrasonic NDT is perhaps better known in its more common applications for thickness gaging, flaw detection, and acoustic imaging, high frequency sound waves can
  • Ultrasonic Flaw Detection
    Of all the applications of industrial ultrasonic testing, flaw detection is the oldest and the most common. Since the 1940s, the laws of physics that govern the propagation of sound waves through solid materials have been used to detect hidden cracks, voids, porosity, and other internal
  • Fundamentals Of Ultrasonic plastic welding
    An understanding of ultrasonic welders helps designers apply this assembly method efficiently. Actuator shown is used for semiautomatic or fully automated CNC plastic-welding applications and includes a converter and booster horn. Modular press system for manual ultrasonic plastic welding includes
  • Ultrasonic Thickness Gaging
    Ultrasonic thickness gaging is a widely used nondestructive test technique for measuring the thickness of a material from one side. It is fast, reliable, and versatile, and unlike a micrometer or caliper it requires access to only one side of the test piece. The first commercial ultrasonic gages
  • Miscellaneous Ultrasonic Applications
    While a majority of the applications for ultrasonic nondestructive testing fall into a few well-known categories, the range of possibilities for the technology is large and new tests are constantly being developed and implemented. The applications section of the Olympus website is meant to cover
