Olympus 38DL PLUS Ultrasonic Thickness Gauge

Unveiling a New Era of Precision

The Olympus 38DL PLUS Ultrasonic Thickness Gauge is not just another instrument; it’s a testament to the evolution of non-destructive testing. Designed and engineered by Olympus, a world leader in optical and digital solutions, this gauge redefines the standards of precision, portability, and versatility. It is an advanced ultrasonic device that excels in measuring the thickness of a vast array of materials, from the simplest single-layer components to complex, internally corroded structures. With its state-of-the-art technology, including THRU-COAT and Echo-to-Echo capabilities, it provides solutions for some of the most challenging measurement tasks across a wide spectrum of industries. This introductory exploration will delve into the core features, technological advancements, and extensive applications that make the 38DL PLUS an indispensable tool for engineers, inspectors, and quality assurance professionals worldwide.

The Science Behind the Measurement

At the heart of the 38DL PLUS lies a sophisticated application of ultrasonic technology. The gauge operates by emitting high-frequency sound waves from a transducer into the test material. These waves travel through the material and reflect off the opposite side or any internal boundaries, such as corrosion pits or a change in material. The gauge then precisely measures the time it takes for these sound waves to travel and return. By knowing the speed of sound within the specific material, the gauge’s advanced algorithms can instantly calculate the thickness with remarkable accuracy. The 38DL PLUS stands out with its ability to use both dual-element and single-element transducers. Dual-element transducers are ideal for internally corroded applications, where they can measure the remaining wall thickness by ignoring the coating. Single-element transducers are used for high-precision measurements of very thin, very thick, or multi-layered materials, providing unmatched versatility for a single device.

Advanced Features for Unparalleled Performance

The Olympus 38DL PLUS is a masterclass in combining ease of use with robust, high-performance features. It boasts a thickness measurement range from a minuscule 0.08 mm (0.003 in.) up to a substantial 635 mm (25 in.), catering to both micro-level and large-scale applications. The instrument’s full-color transflective VGA display ensures excellent visibility in any lighting condition, from bright sunlight to dimly lit inspection sites. One of its most powerful features is its ability to handle complex measurements with advanced algorithms and fast scanning capabilities. This makes it particularly effective for measuring the thickness of very thin layers in demanding applications. The device also includes an extensive internal data logger with a massive capacity to store up to 475,000 thickness measurements or 20,000 waveforms, complete with location codes and comments. This data can be easily transferred to a PC via USB or RS-232 for detailed analysis and reporting, streamlining workflow and documentation.

The Power of Specialized Measurement Modes

A key differentiator of the Olympus 38DL PLUS is its suite of specialized measurement modes, each designed to tackle a specific challenge. The THRU-COAT mode is a game-changer for measuring the thickness of a metal substrate while ignoring the thickness of an overlying coating, such as paint or rust. This is achieved by using a dual-element transducer and a single back-wall echo, eliminating the need for time-consuming coating removal. The Echo-to-Echo mode takes this a step further by using the time interval between two successive back-wall echoes to subtract the coating thickness. For more precise or challenging applications, the single-element transducer modes provide three distinct measurement methods. These modes allow for everything from standard thickness measurements to detailed analysis of internal structures, including optional Oxide and Multilayer modes that are crucial for specific industrial applications like boiler tube inspections or specialized coatings. This comprehensive set of tools makes the 38DL PLUS an incredibly flexible instrument.

Specific Applications in Key Industries

The Olympus 38DL PLUS is a versatile powerhouse with a multitude of specific applications across various industries, providing critical data for quality control, safety, and maintenance. In the aerospace industry, it is used to measure the thickness of composite materials, ensuring structural integrity in a field where precision is non-negotiable. Its ability to handle multi-layered materials is essential for inspecting aircraft components. The automotive industry leverages the 38DL PLUS to measure paint layers, plastics, metals, and multi-layer coatings, which is vital for quality assurance in vehicle manufacturing. For example, it can precisely measure the thickness of a car’s paint job without damaging the finish. In the petrochemical and oil & gas sectors, the gauge is invaluable for measuring the wall thickness of pipes and pressure vessels, especially in areas affected by internal corrosion. This helps prevent catastrophic failures and ensures regulatory compliance. Other specific applications include:

• Boiler tube inspection in power generation plants to detect and measure internal corrosion.
• Chemical processing equipment wall thickness checks to ensure safety and integrity.
• Ship hull inspection to assess wear and tear from corrosion and abrasion.
• Pipeline maintenance and integrity management to monitor for internal corrosion and erosion.
• Precision machining for quality control of metal parts and components.
• Plastics manufacturing to ensure uniform thickness of plastic bottles, containers, and sheets.
• Aerospace component inspection for both composite and metal parts, including fuselage and wing structures.

The Advantage of Portability and Durability

Beyond its advanced technical capabilities, the Olympus 38DL PLUS is designed for the reality of field work. It is remarkably lightweight and compact, weighing just 0.814 kg (1.80 lb), making it easy to carry for extended periods. Its durable, impact-resistant, and water-resistant case is designed to meet IP67 standards, providing excellent protection against dust and water ingress. This rugged design ensures reliable performance in harsh industrial environments. The device’s power system is equally versatile, offering a lithium-ion battery with over 12 hours of operating time as well as the option to use 4 AA auxiliary batteries for extended use in remote locations. This combination of portability and durability means that the 38DL PLUS can be trusted to perform reliably in any setting, from a manufacturing floor to an offshore oil rig.
