DMS Go Thickness Gauge

a high-end thickness gauge which combines an innovative, easy-to-use user interface

The DMS Go from GEs Inspection Technologies business is a high-end thickness gauge which combines an innovative, easy-to-use user interface, powerful data management and an ability to provide accurate, reliable and comprehensive thickness inspection data. It is ideally suited for a wide range of applications including measuring for corrosion in the oil and gas sector and in power generation.
The DMS Go uses the same operating platform as the USM Go portable flaw detector. By means of a simple software purchase your DMS Go can benefit from all the USM Go functionalities and perform advanced flaw detections.


High Performance Thickness Measurement
-High measurement stability and reliability resulting from zero crossing measurement technique.
* Automatic gain control for excellent repeatability and corrosion monitoring
* Built-in temperature compensation algorithm allows accurate measurement up to 540C (1000F).
* Multiple Calibration and Zeroing modes for repeatable accuracy, including:
*2-point calibration
*1-point calibration with Manual on-block zeroing
* 1-point calibration with Auto zeroing for every measurement (coupled)
1-point calibration with User zeroing in the air (uncoupled)
* Multiple measurement modes, for every application, including:
* A-Scan
* Thickness
* B-Scan
* Min /Max
* Differential
* Support of several standard probes and the capability to support virtually any probe using the custom probe setup feature
* Ability to operate in harsh environments with IP67 sealing
Topcoat Technology Supported
-With the patented TopCOAT method we have been able to optimize the corrosion measurement through paint coatings: this method makes it possible to measure materials showing heavy corrosion on backwall surfaces, and even the slightest pitting can be detected thanks to a high gain. The paint coating and base metal are measured in one measurement process, and displayed simultaneously.
Auto-V Supported
-If your components are uncoated, you have the Auto-V feature at your disposal. It is a clearly simplified version of the conventional thickness measurement and, as such, a unique method. Auto-V even allows you to measure the thickness of components with unknown material velocity. This enables you to measure different uncoated materials without any additional calibration and without any calibration standards. Its not necessary to know the material velocity to be able to measure this previous disadvantage no longer exists.
Robust Construction
* A robust moulded rubber casing to withstand the harshest environments and significantly reduce downtime.
* IP 67 immersion test (P67 / IEC529 - dust proof / dripping water proof as per IEC 529 specification for IP67 classification)
* Drop test (514.5 Procedure II; 516.5 Procedure IV)
* Vibration test (Mil-Std-810F; 514.5-5 Procedure I, Annex C)

High Capacity Data Recorder and Compatibility with Powerful Data Management Systems

The DMS Go offers powerful data recording and data management capability to meet the most demanding of thickness gauging and corrosion inspections. Important features include:
* Powerful on-board data recorder has capacity of hundreds of thousands readings and permits the storage of A-scan, B-scan and MicroGRID attachments to thickness readings.
* Data can be organized using pre-set (linear, grid, boiler), custom (custom linear, custom grid) or advanced (3D and 4D in UltraMATE) files structures.
* Data transfer is via industry standard removable SD card up to 16 GB.
* A USB port is included to allow instrument to PC connection if preferred no driver needed, works with all versions of Windows.
* Export in different file formats (xls, html, dat, csv, pdf) to allow easy integration with user data management softwares and user quality control systems.
* Compatible with UltraMATE and UltraMATE lite data management programs to allow for comprehensive analysis and documentation of data.
* The data recorder files can be interfaced with other 3rd party software programs using a GEsoftware development kit, supplied on CD.

HT350x Sensor
* Nominal frequency: 5.0Mhz
* Nominal bandwidth: 100%
* Operating Mode: Delay
* Typical measuring range: 2 - 13 mm (0.080 - 0.5)
Measuring range is affected by material properties, coupling and other factors
* Contact diameter: 21 mm (0.820)
* Couplant: Metal foil
* Coupling pressure: Varies depending on test surface dimensions and finish
* Mounting: Adaptable clamping system
* Cabling: CMX configuration 5 m (16.4 ft) length armor jacket coax cable to open leads (no connector)
Stand Alone configuration - 5 m (16.4 ft) length coax cable to Lemo #1 connector
* Delay length: 17.7 mm (0.7)
* Delat material: 303 Stainless steel / Delay sound velocity : 5790 m/S (0.0228/S) (approx. values)
CMX-HT Sensor Node
* Probe system: Single element 5Mhz probe with stainless steel delay line. The probe is clamped onto the pipe and coupled to the surface with a gold foil.
* System thickness resolution: The resolution of the thickness reading through the complete system is the smallest change that can be reliably detected. This is influenced by short-term temperature fluctuations. These variations will result in changes in the temperature profile across the pipe wall.
* Thickness accuracy: Accuracy depends on correct system configuration of material velocity. Calibration standards or material specifications of the material are required for accurate results.
This accuracy applies for uniformly corroded inside wall. Highly localized pitting may not be detected.
* Thickness resolution single reading: With temperature variations at rates less then 1C (33.8F) per minute over a 5C (41F) range, the resolution is improved to the value obtained using regression analysis.
* Thickness reolution with regression: Reading errors due to short-term fluctuations are removed after taking a series of readings over time and performing a regression analysis.

Intelligent Storing and Managing

The DMS 2s on-board Data Recorder makes all the options for up-to-date documentation and modern data management available to you:
* Memory capacity for 150,000 readings and 1,100 A- or B-scans (extendable)
* Flexible adaptation to the measurement task by eight different file structures according to the arrangement of measuring points most often encountered.
* Subsequent insertion/deletion of readings within a file
* Storage of additional information for each measurement location: probe, material velocity, date, time, calibration, etc.
* Comment line with 64 characters accessible at any time.
* Microgrid: You can insert up to 81 readings, in 2 x 2 to 9 x 9 grids, per measurement point at any time during the test using this function. By doing this, an analysis can be made in the direct vicinity of a critical measurement point.

Connectivity

A standard USB connection to allow data to be downloaded from the flaw detector for further analysis or storage. The instrument is standard delivered with a 2 GB SD memory card (can accommodate up to 16GB card size).

Reports are produced in jpeg or bmp format so there is no need for special reading software.
A simple on-board data logger to collect and save thickness measurements.
