38DL PLUS™ Ultrasonic Thickness Gauge Advanced Features, Simple Operation

Advanced Features, Simple Operation, Rugged, and Reliable The 38DL PLUS™ ultrasonic thickness gauge combines ease of use and accuracy with a durable design. Ideally suited for almost every ultrasonic thickness gauging application, this versatile handheld gauge is compatible with a full line of dual and single element transducers. You can use it in applications ranging from wall thinning measurements of internally corroded pipes with dual element probes to very precise thickness measurements of thin or multilayer materials with single element transducers. The 38DL PLUS gauge comes standard...

What Makes This Thickness Gauge Different from Others? The 38DL PLUS™ thickness gauge is built to meet the challenges of demanding applications and withstand tough conditions in the field and on the production floor. Whether you work in wet or dusty conditions, cold or hot climates, or bright or dark areas, the 38DL PLUS gauge can handle any inspection job. Need an instrument tough enough to tolerate shocks, drops, and rough handling? The 38DL PLUS gauge, with its protective rubber boot and military-rugged design, is your answer. Built for Tough Environments ❯ Compact, weighs only 0.814 kg...

One of the major applications of the 38DL PLUS™ gauge is measuring the remaining thickness of pipes, tubes, tanks, pressure vessels, hulls, and other structures affected by corrosion or erosion. Dual element transducers are most commonly used for these applications. > Automatic Probe Recognition for standard D79X series dual element transducers > Ten custom dual element transducer setups > Optimized default gain during calibration for dual element transducer > V-Path Builder for custom V-path compensation > Calibration doubling warning when echo doubling may occur during calibration >...

Oxide/Scale Measurement Option Temperature Compensation Variations in material temperature affect sound velocity and the accuracy of thickness measurements. The temperature compensation feature enables you to manually enter the calibration block's temperature and the current (high) temperature at the measurement points. The The 38DL PLUS™ gauge automatically displays the temperature-corrected thickness. This feature uses advanced algorithms to measure the thickness of oxide/scale buildups inside boiler tubes. The gauge simultaneously displays the metal thickness of the boiler tube and the...

Dual Element Transducers for Corrosion Gauging All standard dual element transducers feature Automatic Probe Recognition, which automatically recalls a default V-path correction for each specific transducer. * Thickness range dependent on material, transducer type, surface conditions, and temperature. Full range may require Gain adjustment. ** Maximum temperature with intermittent contact only. t Stainless steel cable available; consult Olympus for details. n Not certified to EN15317; The MTD705 is issued a TP103 test certificate in accordance with ASTM E1065. tn Transducers used with...

Additional Products Couplants Calibration Test Blocks Transducer Cables Liquid couplant is almost always necessary to provide acoustic coupling between the transducer and the test piece. We offer various types of couplants to suit virtually all applications. Test blocks are necessary for the calibration of ultrasonic thickness gauges and should be used to maintain and verify the accuracy, dependability, and reliability of ultrasonic measurements. Blocks are held to tighter tolerances than stated in the ASTM E797 code. Metric test blocks are available. A wide selection of transducer cables...

Thickness Measurements on Plastics, Metals, Composites, Glass, Rubber, and Ceramics When using single element transducers, you can make accurate thickness measurements on metals, plastics, composites, glass, ceramics, and other materials. These transducers are available in a wide range of frequencies, diameters, and connector styles. The High Resolution software option enables you to make very precise measurements at a resolution of 0.0001 in. or 0.001 mm. ❯ Standard resolution of 0.01 mm (0.001 in.) for all transducers ❯ High Resolution software option can display measurements up to 0.001...

Data Logger and PC Interface The 38DL PLUS™ gauge has a full-featured internal, bidirectional alphanumeric data logger that is designed to easily collect and transfer thickness readings and waveform data. ❯ Internal memory of 475,000 thickness readings or 20,000 waveforms with thickness readings ❯ 32-character file name ❯ 20-character ID# (TML#) ❯ 9 file formats: Incremental, sequential, sequential with custom point, 2D grid, 2D grid with custom point, 3D grid, 3D custom, boiler, and manual ❯ Stores up to 4 comments (notes) per ID# (TML) ❯ Stores comments (notes) at an ID# or to a range of...

Delay Line Transducers Microscan™ delay line transducers provide excellent performance on very thin materials, at elevated temperatures, or with applications that require a high degree of thickness resolution. * Exact range depends on material sound velocity, transducer frequency, part geometry, and surface condition. Replaceable Delay Lines Delay lines function as a protective buffer between the surface of the test piece and the transducer element.
