An ultrasonic thickness gauge is a measuring instrument for the non-destructive investigation of a material's thickness using ultrasonic waves. The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements.
Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...
The first efforts to use ultrasonic testing to detect flaws in solid material occurred in the 1930s. [1] On May 27, 1940, U.S. researcher Dr. Floyd Firestone of the University of Michigan applies for a U.S. invention patent for the first practical ultrasonic testing method.
In some cases, hundreds of meters can be inspected from a single location. There are also some applications for inspecting rail tracks , rods and metal plate structures. Although guided wave testing is also commonly known as guided wave ultrasonic testing (GWUT) or ultrasonic guided waves (UGWs) or long range ultrasonic testing (LRUT), it is ...
Toyota introduced ultrasonic Back Sonar on the 1982 Toyota Corona, offering it until 1988. [7] On December 13, 1984, Massimo Ciccarello and Ruggero Lenci (see List of Italian inventors ) entered in Italy the patent request for ultrasonics Parking sensors, and on November 16, 1988, the Ministry of Industry granted them the Patent for industrial ...
The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine.
Laser-ultrasonics uses lasers to generate and detect ultrasonic waves. [1] It is a non-contact technique used to measure materials thickness, detect flaws and carry out materials characterization. The basic components of a laser-ultrasonic system are a generation laser, a detection laser and a detector.
The company was founded in 1946 by Norman G. Branson, a research engineer for General Electric.He remained president and CEO of the company until 1967. In 1984, Branson Ultrasonics was purchased by Emerson Electric.
