How does ultrasonic sensor help in Non-Destructive Testing? Ultrasonic testing is a way to test material, to know more details about its internal state and details like thickness. It is a non-destructive testing method which the material does not get damaged or chipped when testing. The equipment used for this testing is the ultrasonic sensor. This device sends high-frequency sound waves into the material under investigation, and as the wave travels back, the time travelled is measured and deduced to its condition. How does ultrasonic sensor work? It has a transducer to emit high-frequency sound waves into the material under test. The frequency is much higher than the normal hearing range and can go up to 5000 kHz. These sound waves travel through layers and act only when they experience a change in medium or a defect. Upon striking a varied surface, the waves travel back to the source, an ultrasonic sensor. The sensor records the time travelled from the sensor, to the material and return to the sensor. It also notes any change in its frequency. Experts study and analyze these reports to understand if there is a flaw in the specimen. The premium quality, feature-rich sensor also stores the records for future reference. It is non-destructive The ultrasonic sensor is a piece of equipment that falls under the category of non-destructive testing techniques. Unlike destructive methods, you wouldn't have to dig through the layers to measure the thickness. Moreover, there will not be any chipping of the topmost layer to identify the material or test its durability. You only have to place the sensor on the object to get the desired results. Perks of using the sensor There are countless benefits of using the ultrasonic tester. Some of them are: ·
High penetration and sensitivity allow the deep detection and small flaw detection.
