Quantitative Analysis of Pulsed Ultrasonic Beam Patterns Using a Schlieren System
Abstract The acoustic output from pulsed ultrasonic transducers has traditionally been analyzed with a hydrophone. Recently, a new faster technique has been developed using the principles of optical diffraction. This schlieren method allows the direct two-dimensional visualization of the ultrasonic beam as a pulse train. In order to obtain quantitative information in the form of temporal-average ...

Approximate Material Properties in Isotropic Materials
A very important part of the design of ultrasonic transducers and ultrasonic measurement systems is the selection of materials. Typically, materials must be screened on the basis of their acoustic velocity, impedance, and attenuation. The final selection of a material is based upon many other factors, such as how well it adheres to epoxy, its linearity, or how much water it absorbs. This paper is ...

Silicon Substrate Ringing in Microfabricated Ultrasonic Transducers
Abstract Experimental and theoretical evidence of silicon substrate ringing in microfabricated ultrasonic transducers is presented. This ringing is clearly observed in immersion transducers with a 650 µm thick substrate at 7 MHz and harmonics. An analytical model of the ringing is introduced, and simulations based on the model are shown to agree with experimental observation. Experimental ...

Ultrasonic Level Sensor Working Principle
An ultrasonic level sensor is a device that utilizes sound waves to measure the level of a substance, such as a liquid or solid material, in a tank, container, bin or vessel. It is a continuous level measurement device that provides real-time, non-contact measurement. The basic working principle involves transmitting a short pulse of ultrasonic sound from the sensor and measuring the time it ...

Smco magnets facts
Samarium (Sm) magnets are rare earth magnets manufactured into two series. The first series is sometimes referred to as SmCo5 (Co means cobalt), which is usually a high energy product of about 18 to 22 MGOe. The second is the most commonly known as Sm2Co17, which is a higher energy product of about 22 to 30 MGOe. It combines 2 Sm atoms and Co atoms between 13 and 17. It is basically an alloy of ...

How an Ultrasonic Flow Meter Works
An ultrasonic flow meter utilizes ultrasound to measure the velocity of a fluid and is used in a variety of fluid applications. Ultrasonic flowmeters are ideal for water and other liquids. Clamp-on ultrasonic flow meters achieve high accuracy at low and high flows, save time with no pipe cutting or process shutdown, and are not affected by external noise. Here’s how ultrasonic flow meters ...

Two Technologies for Flow Measurement from Outside a Pipe
Doppler and Transit Time are two very popular types of flow meter for non-invasive measurement of flow in full pipes. We tend to confuse these technologies because they are both ultrasonic and both measure flow by using sensors clamped onto the outside of a pipe. In the real world they actually work best in opposite applications. Success in your installation depends on understanding the ...

Does Ultrasonic Testing Have Thickness Limitations?
Ultrasonic testing has become one of the most common and effective methods of nondestructive testing. Without the dangers posed by radiography, the cumbersome setup of liquid penetrant testing, or the surface-level limitations of visual inspection, ultrasonic testing allows fast, simple inspections of many materials. Ultrasonic inspection also achieves deeper material penetration than most other ...
