DM5E SERIES WALL THICKNESS GAUGE
The DM5E is a basic ultrasonic thickness gauge designed to perform thickness tests on equipment such as pipes or tanks in the oil & gas industry or the petrochemical and power industries.
The DM5E series replaces the Krautkramer DM4E, DM4, DM4DL and StressTel TMIKE E family of corrosion thickness gauges. The DM5E is designed for operation in the harshest of working environments, performing wall thickness measurements on pipelines, pressure vessels and storage tanks in the oil and gas industry, as well as the petrochemical and power generation sectors.
The battery powered gauge is able to perform for up to 60 hours of use and includes features such as Min/Max capture and B-Scan generation. Differential thickness measurement allows it to compare measured and nominal thickness as well. The lightweight unit includes 2 AA batteries, a 100 g bottle of couplant, a plastic carrying case, a brief instruction card, an operating manual and an ISO 17025 certificate of calibration.
Product Data Sheet
All versions of the DM5E have the same user-friendly operator keypad interface. This has a central Mode key, a calibration/on/off key, two function arrow keys to activate and set functional control and four arrow keys for adjusting parameter values and for navigating through the intuitive single level menu. The keypad allows access to all calibration, set-up and measurement display modes of the instrument. With the DL version, a file display mode allows users to create and store thickness reading s in files. All calibration is menu-driven and the operator is guided through every step. There is a built-in calibration reminder, which can be set to remind the user to calibrate after a specified number of measurements or after a given time period
HIGH PERFORMANCE PROBES
A new set of ultrasonic probes has been developed for the DM5E family to provide the instruments with optimized performance, even at very high temperatures. The DA5xx series includes a 5 MHz standard probe for general purpose applications, a 2MHz version, for high penetration as well as a 7.5MHz fingertip probe to be used for “thin” materials. A newly developed 5MHz high temperature probe offers an operating range from -10°C up to +204°C(continuously).
MEASUREMENT THROUGH COATING
Both the DM5EDM and the DM5E DL offer Dual Multi Measurement. Virtually all components and structures subjected to thickness measurement will have some kind of protective coating. Such coatings, including paint, contribute significant error to thickness measurements of underlying metal walls when using conventional methods. In addition, the removal of coatings, and their subsequent reapplication, involves considerable cost and time. With the field proven Dual Multi feature there is no need to remove any protective coating. It is only necessary to select Dual Multi mode, place the probe in position and take the measurement.
ALL VERSIONS OF THE DM5E OFFER A RANGE OF MEASUREMENT DISPLAYS.
- Normal where the thickness value appears as large digits in the centre of the display
- Mini Scan This is a minimum thickness scan and allows the user to run the probe over the wall surface. After the evaluation period, the minimum material thickness measured is displayed.
- Maxi Scan. This is a maximum thickness scan and is exactly the same as a Mini Scan apart from the fact that the maximum thickness measured is displayed.
- DIFF/RR%. This scan compares the measured thickness with a user-specified nominal thickness. The dimensional difference between the two values is displayed, as is the percentage difference.
- B-Scan This displays a graphic representation of a B-scan showing minimum thickness values. The graph is derived by measuring and recording at 1 point per second.
Although thickness measurements are considered as a simple inspection task studies have shown that there is a risk for wrong thickness measurements. Due to the complexity of certain thickness gages wrong instrument settings could result in faulty results.
With the new DM5E we offer the field approved, simple intuitive CL5 user interface and in addition to that the password protected Advanced Configuration Menu allows you to lock important settings and functions.
This means: no more faulty reading as a result of wrong calibration, or unintended changes to the instrument configuration.
Fast, reliable measurement and reporting is in demand, enabling you to act fast on corrosion issues to ensure uptime and long life of your equipment and operations. Especially in the current economic conditions, investments have to be evaluated very carefully - the DM5E series offers flexible solutions, that are easily upgradeable to the changing situations and the related functionality needed.
