On June 1, 2010, Olympus Corporation (President: Tsuyoshi Kikukawa) will commence international sales of the 38DL PLUS Ultrasonic Thickness Gage. This new nondestructive testing device allows objects to be inspected without the need for destruction or disassembly. It will go on sale in Japan in the fall of 2010.

An ultrasonic thickness gage determines the thickness of objects by emitting ultrasonic waves and measuring the time required for the waves to bounce back. They are used for quality inspections of products made from plastic, metals, glass, composites, and various other materials, and also to measure the remaining wall thickness of internally corroded pipes and tanks.

Existing thickness gages manufactured by Olympus have been configured for a specific range of applications, which means that a different gage was required for each type of inspection. With the 38DL PLUS users can configure this single device to carry out a wide variety of inspection tasks by purchasing software options for additional capabilities, such as precision thickness measurement at resolutions of up to 0.001 mm (1µm), or the ability to take simultaneous thickness readings of individual layers in multilayered materials. Because the 38DL PLUS is designed to meet various durability standards, including the IP67 waterproofing standard, it can be used with confidence in a wide range of weather conditions and under harsh site conditions.

Main Features

1. All-in-One Model-Support for Multiple Inspection Needs in a Single Unit
Additional capabilities can be added to the standard functions of the 38DL PLUS simply by purchasing software options. In this way, the 38DL can be configured to carry out a variety of inspection tasks that would have required four different models from the existing Olympus range.

Code-Activated Options (License Purchase Required)

• Oxidation scale measurement
  - This optional feature allows the 38DL to measure oxidation scale on the inside of boiler tubes.
• High-resolution display
  This feature increases the display resolution from the standard 0.01 mm level to 0.001 mm (1µm).
• Multilayer measurement
  With this option, the 38DL can be used to measure the thickness of multilayered materials, such as preforms for PET bottles and plastic fuel tanks.
• High penetration
  This feature configures the 38DL PLUS to transmit low-frequency waves, allowing it to measure materials that are normally unsuitable for ultrasonic measurements, such as very thick layers of rubber and fiber glass.

2. Durability and Reliability under Harsh Conditions-Designed to Meet IP67 Waterproofing Standard
The 38DL PLUS is designed to meet the IP67 waterproofing standard and U.S. Department of Defense standards, including standards for shock and dropping tests. It will perform reliably under various weather conditions and in harsh environments.

3. Internal Data Logger-Storage for 475,000 Thickness Readings or 20,000 Waveforms
Measurement data can be stored and managed in the internal data logger. It can also be stored in text or CSV formats on standard micro SD cards.
