Information on Ultrasound Technology

Posted on

Ultrasonic technology is a method of measuring the density of materials using sound waves. It works by sending high frequency sound waves through a material, and then analyzing how much time it takes for those waves to return back to the transducer (the device that sends out the sound). By knowing the speed at which the wave travels through the material, we can calculate its density.

Ultrasonic technology was first developed in the 1930’s, and has since been used in many different industries including food processing, pharmaceutical manufacturing, and oil exploration. In the medical industry, ultrasound technology is commonly used to measure blood flow, detect tumors, and guide surgeries.

Ultrasonic testing equipment consists of two major components: the transmitter and receiver. The transmitter emits ultrasonic waves, while the receiver detects them. There are three types of transmitters: single-element, multi-element, and phased array. Single-element transmitters emit a single beam of ultrasonic waves. Multi-element transmitters emit several beams of ultrasonic waves simultaneously. Phased array transmitters emit a series of pulses of ultrasonic waves, which bounce off the object being tested and create a pattern of echoes.

The receiver converts the received signals into electrical impulses, which are then analyzed by a computer. The computer processes these impulses and displays the results on a screen.

There are two ways to use ultrasonic testing equipment: contact mode and noncontact mode. Contact mode uses a probe to touch the surface of the material being measured. Noncontact mode does not require physical contact with the material being tested. Instead, it uses a sensor to send out ultrasonic waves and analyze the reflected signal.

Contact mode is often used for testing metals, plastics, ceramics, and composite materials. Noncontact mode is used for testing wood, concrete, stone, and asphalt.
