  • Ultrasonic Transducers
    Ultrasonic transducers are used for a variety of purposes such as flaw detection, thickness gauging, material research & medical diagnostics, biomedical applications, nondestructive application evaluations, penetration of thick materials. The basic mechanism used in these devices involves the transformation of sound energy into electrical energy and vice versa.
  • Ultrasonic Sensors
    Ultrasonic sensors are small devices used to detect the presence of intruders and other foreign objects. These can discreetly be placed in courtyards and inside homes to detect the presence of moving objects alien to the surroundings. They operate at frequencies in the range of twenty-five to forty kilohertz, which is way above the human hearing range.
  • Ultrasonic Nebulizers
    Ultrasonic Nebulizers are devices that use ultrasonic sound waves to convert liquid medication into fine mist that can be inhaled directly into the lungs through a facemask or mouthpiece. These are generally used by asthmatic patients and other individuals suffering from allergies. They are also preferred due to their ability to perform quickly and quietly.
  • A Guide To Ultrasonic
    Ultrasonic generally refers to acoustic frequencies above twenty thousand hertz, which is the upper limit of human hearing range. These frequencies are however audible to certain animals such as mice, bats, dolphins, and dogs that have a higher hearing range as compared to humans. The human inability to hear ultrasonic sound waves is caused by the middle ear that acts as a low-pass filter.
  • Touch Screen Displays
    A touch screen display is a touch sensitive input device that performs both the functions of the video display unit and the input devices (keyboard and mouse).
