Customised ultrasonic measurement products

5 October 2017

As specialists in the design, development and manufacture of a wide range of ultrasonic measuring equipment devices, our offering goes far beyond just a catalogue of standard products.

Our highly skilled Engineering and Research team have over 25 years’ experience in the development of cutting-edge ultrasonic measurement products used extensively in the QA of medical devices, to provide industry with ultrasonic non-destructive testing (NDT) capability and within academia and national measurement institutes throughout the world.

ultrasonic technologyThis means that the company is ideally placed to help customers with the research and development of customised ultrasonic design concepts to fulfil a particular need.

To illustrate this capability let us look at an example of the challenging work we have recently completed.

The requirement of this particular customer was for a short-range, high-resolution ultrasonic depth gauge. The novel application for ultrasonic technology involved a high-resolution, two-dimensional array. Each element of the array was capable of functioning as a short-range pulse/echo transducer for depth gauging. The intended outcome was a high-resolution image of an irregular surface.

In order to advance this concept beyond the research stage within a university, the company sought an industrial partner capable of developing the project to completion. We became involved with the project to look specifically at the front-end ultrasonic sensor.

The product development process was based upon a high degree of interaction and co-operation between Precision Acoustics and the customer and the sensor development considered many aspects including optimisation of backing material; preparation of high-density sensor arrays; generation of short duration ultrasonic pulses; and simple but reliable inter-connection methods.

One of the critical factors in the success of this project has been the application of cutting edge electronic process to the ultrasonic sensor production. We have now completed the first batch of pre-production arrays (with 4096 sensor) and have also produced next-generation devices with 16,384 sensors.

Do you have a challenging project or application in the field of ultrasonic measurement? We’d love to hear from you.
