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.
A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion and erosion. Ultrasonic testing is extensively used to detect flaws in welds.
Ultrasonic sensors are also used to detect intruders; the ultrasound can cover a wide area from a single point. The flow in pipes or open channels can be measured by ultrasonic flowmeters, which measure the average velocity of flowing liquid. In rheology, an acoustic rheometer relies on the principle of ultrasound.
Ultrasonic density meters work on various principles to calculate the density. One of the methods is the transit-time principle (also known as the time of flight principle). With this technique, a sensor is typically installed in the pipe, which has an ultrasonic transmitter and an ultrasonic receiver in one construction.
Optical interferometry, applied to biology and medicine, provides sensitive metrology capabilities for the measurement of biomolecules, subcellular components, cells and tissues. [101] Many forms of label-free biosensors rely on interferometry because the direct interaction of electromagnetic fields with local molecular polarizability ...
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.
Different types of analysis modes are available in high-definition SAM. The main three modes are A-scans, B-scans, and C-scans. Each one provides different information about the integrity of the sample’s structure. [6] The A-scan is the amplitude of the echo signal over ToF. The transducer is mounted on the z-axis of the SAM.
Instead of amplitude, TOFD uses the time of flight of an ultrasonic pulse to determine the position and size of a reflector. In a TOFD system, a pair of ultrasonic probes sits on opposite sides of a weld. One of the probes, the transmitter, emits an ultrasonic pulse that is picked up by the probe on the other side, the receiver.
