38DL PLUS® Ultrasonic Thickness Gage:
The 38DL PLUS is an innovative instrument that signals a new era in ultrasonic thickness gaging. Ideally suited for almost every ultrasonic thickness application, this handheld thickness gage is fully compatible with a full line of dual and single element transducers. The versatile 38DL PLUS can be used 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 comes standard with many powerful but easy-to-use measurement features and a host of application-specific software options. Its sealed case is designed to meet IP67 requirements to withstand the rigors of very wet or dusty environments. The color transflective VGA display provides superior readability from bright sunlight to complete darkness. It features a simple, ergonomic keypad that can be operated with the left or right hand for easy access to all functions.
The 38DL PLUS is designed to meet the challenges of demanding applications and built to withstand tough conditions in the field and on the production floor. Whether you work in very wet or dusty conditions, cold or hot climates, or bright or dark areas, the 38DL PLUS can handle any inspection job. Need an instrument tough enough to tolerate shocks, drops, and rough handling? The 38DL PLUS with its protective rubber boot and designed for IP67 rating is your answer.
The optional 38-Link wireless adaptor enables any existing 38DL PLUS thickness gage to send and receive data using Bluetooth® or wireless LAN*.
The 38-Link adaptor provides three powerful wireless communication capabilities:

One of the major applications of the 38DL PLUS 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.
This powerful optional feature allows the 38DL PLUS to be connected to a linear encoded scanner to generate encoded B-scans. The 38DL PLUS will capture and store the distance traveled information along with corresponding thickness readings. The waveform at the minimum thickness is also captured. The user can select the distance between measurements and select between bidirectional and unidirectional modes. Up to 10,000 thickness readings can be stored in a single B-scan.
A single back-wall echo is used to measure true metal thickness. You can display the metal and coating thicknesses, each adjusted for their correct material sound velocities. There is no need to remove paint and coatings from surfaces. THRU-COAT measurements use the D7906-SM, D7906-RM, and D7908 dual element transducers.
Variations in material temperature affect sound velocity and accuracy of thickness measurements. The temperature compensation feature allows you to manually enter the calibration block's temperature and the current (high) temperature at the measurement points. The 38DL PLUS automatically displays the temperature-corrected thickness.
38DL PLUS uses advanced algorithms to measure the thickness of oxide/scale buildups inside boiler tubes. The gage simultaneously displays the metal thickness of the boiler tube and the thickness of the oxide layer. Knowing the thickness of the oxide/scale helps predict tube life. We recommend using M2017 or M2091 transducers in this application.
This new and patented feature allows you to build a custom V-Path compensation curve for almost any dual element transducer. These curves can be saved and recalled along with custom setups for most dual element transducers.
You simply calibrate and enter the known thickness with a minimum of 3 and up to 10 calibration points, and the instrument will create the V-path.
All standard dual element transducers feature Automatic Probe Recognition, which automatically recalls a default V-path correction for each specific transducer.
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 allows you to make very precise measurements at a resolution of 0.0001 in. or 0.001 mm.
This option allows you to use low frequency single element transducers (as low as 0.5 MHz) to measure thick or sound attenuating materials such as rubber, fiberglass, castings, and composites.
This software option calculates and simultaneously displays thickness measurements of up to four individual layers.
It also displays total thickness of selected layers. Typical applications include thickness of barrier layers in plastic fuel tanks, bottle preforms, and soft contact lenses.
Ultrasonic thickness gage inspections can be time consuming—thousands of individual measurements recorded in the field and painstakingly compiled into data management software. And if these readings are recorded by hand, inaccuracies can lead to longer equipment shutdowns and added time and costs for owner-operators.
The 38-Link adaptor enables any 38DL PLUS® thickness gage to send and receive data using a Bluetooth® or wireless LAN connection*, simplifying data management and enabling a more efficient workflow. Upgrading is simple—the 38-Link adaptor easily attaches to the gage’s rubber boot.
*Wireless LAN and Bluetooth dongle availability depends on your region. Contact your local Olympus sales representative for more information.
Wirelessly connect to the Olympus Scientific Cloud (OSC) to take advantage of powerful tools. With a free OSC account and the 38-Link adaptor, you can:
Use the Olympus Link mobile app and Bluetooth® to send thickness data to your phone or tablet. From your mobile device, share thickness data over text message or email, or save the data as a text file for easy import to a spreadsheet. You can also send data to compatible third-party mobile applications.
Use the optional Link-Wedge software and Bluetooth to send data from your gage to an active Windows® software application. The software can populate data into almost any Windows-based data entry program. The Link-Wedge is only compatible with Windows 10.
Olympus NDT offers a complete selection of transducers, cables, couplants, calibration test blocks, and accessories to meet a wide variety of ultrasonic precision thickness gaging applications.
