  • 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
  • Ultrasonic Primer: The Theory Behind Ultrasonic Cleaning
    The heart of any ultrasonic cleaning system is the transducer. At the present time, the two types of transducers offered are magnetostrictive, made of nickel or its alloys, and electrostrictive, made of lead zirconate titanate or other ceramics. Electrostrictive materials change their physical
  • Ultrasonic Medical Immersion System
    The customer manufactures ultrasonic water immersion systems. A commercial ultrasonic transducer is positioned in front of a test object. The transducer, excited by driving electronics, emits a burst of ultrasonic energy. This same transducer then detects echoes reflected off the test object, which
  • 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 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
  • How Ultrasonic Welding Works
    Ultrasonic assembly utilizes an acoustic tool called a horn to transfer vibratory energy through the part to the joint area, where it is converted to heat through friction that melts the plastic. Ultrasonics can be used to join not only rigid thermoplastics, but fabrics and films as well. Branson
  • Checklist for Superior Ultrasonic Cleaning
    Ultrasonic cleaning is a result of sound waves introduced into a cleaning liquid by means of a series of mounted to the cleaning tank. The sound travels throughout the tank and creates waves of compression and expansion in the liquid. In the compression wave, the molecules of the cleaning liquid
  • 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
  • Arbitrary Ultrasonic Generator
    Ultrasonic generation pulses must be varied to accommodate different types of ultrasonic transducers. General-purpose highly damped contact transducers are usually excited by a wideband, spike-like pulse that is provided by many common pulser/receiver units. Lightly damped transducers, used
