Structural Diagnostics, Inc. was formed in 1994 and is a leading manufacturer of automated inspection systems used to determine the fitness for use of high value components and systems. The branch of technology used for undertaking these critical inspections is known as Non Destructive Testing (NDT). The requirement is to perform tests to identify defects within a structure without damaging or impairing its fitness for use in any way.

Many of the techniques used are closely related to medical diagnostics and employ much of the same technology; ultrasonics, X-ray, computed tomography, NMR. Others take advantage of changes in the physical properties of the structure such as electrical conductivity, heat transfer and vibration characteristics.

The staff of SDI is highly qualified in the field of NDT and have recognized expertise and national accreditation in its application. They are well known to the customer base and have a proven track record in supplying effective solutions to inspection problems rather than merely supplying equipment.

SDI has an established national and international distribution network through local agents. Historically, 30% of SDI's sales have been into overseas markets. SDI's focus is on the automation of these NDT test methods and the development of improved instrumentation. This has resulted in a product line with three main groups:

• Automated Test Systems
• System Accessories
• Instrumentation

In addition, a number of spin-off products have been developed with general applicability beyond the NDT market. These include low cost propriety motion control hardware and software suitable for a wide range of robotics applications. All aspects of product design and manufacturing are carried out in house. In addition to the UT systems, SDI manufactures a range of specialized UT instrumentation and motion control products.
