What is an ultrasonic converter?

Ultrasonic converter is an electrical component that converts ultrasonic sound waves outside the range of human hearing into AC (AC) or direct current (DC) electrical signals, which are then transmitted or recorded. Usually, such devices are built on crystals that show a piezoelectric effect that performs electrical current in response to mechanical voltages or vibrations. Crystals have a directly proportional output to the power of input sound waves or voltages, making them useful measuring devices as an ultrasonic converter. They have been used in industrial applications to monitor the level of fluid in the tank and in modern cars since 2011 for the sensors of the echo position to indicate objects in close proximity to the roadproof, which backs up or pulls into the garage. Because the ultrasonic converter can also play the role of ultrasonic transmitter via input electrical output, in many cases they offer the ability of a primitive Sonar type. Sound waves can reflectFrom the surface and the distance to this surface measured by the time and frequency of the wool that bounces back.

electrical devices that convert one form of energy into another, such as ultrasonic sensors, often have extended applications in electronics and industry. Now there are many diverse uses for an ultrasonic converter, including environmental inspections of buildings, for example in humidifiers where they evaporate the surface of water and in Burl burgers detect objects moving otherwise clear. Ultrasonography also relies on the principle of ultrasonic converter in medicine, where 1o 30 megaertz sound waves are used to remotely generate images for muscle, internal organs and blood vessels in the human body, as well as fetal condition during pregnancy.

Since the age of 40 of the 20th century, an ultrasound converter has been incorporated into a test device to detect deficiencies in a number of applications related to Sonar. They can be used to find fine cracks, cavities or porous sections in concrete and foundations, damaged or broken metal welds and deficiencies in other materials such as plastic, ceramics and composites. The devices are versatile because the sound waves that emit are affected by any medium, whether liquid, solid or gas. However, in the detector used to measure the condition of the gas and ultrasonic converter, the intermediate is usually placed, because the sound waves are otherwise poorly performed and recorded in the gas medium.

Field of defect detection for ultrasonic technology is divided into five different converter constructions: contact, beam angle, delay line, immersion and converters with double element. Contact converters must be close to contact with what it measures, such as a shame search engine in a building used to detect wooden beams behind the walls. The dipping converter is waterproof and placed in the flow of liquid. To measure welds and under the conditions of highTemperatures are used both the angle of the beam and the delay of the lines of the ultrasonic converter. The converter with a double element is simultaneously transmitter and receiver for continuous monitoring of harsh or potentially defective surfaces.
