Progressive design
Not only does it look good; behind its modern looks the DuraVision also offers lots of special technical features. The use of PLC components is a guarantee for the highest degree of process precision. Furthermore, the modular kit concept enables the DuraVision to be completely tailored to your requirements. The DuraVision is as equally effective in clinically clean laboratory environment as it is in the dirt of everyday manufacturing processes.
|
|
|
| |
 |
|
Saving time
Fully automatic brightness adjustment, optimised autofocus, rapid turret-, swivel body- and cross slide movements, plus intuitive operation, all help to reduce test cycle durations. After test completion results and test reports can be imported straight into your company network. Especially when testing samples with different shapes or sizes, the intelligent design of the machine allows adaptations to be made very quickly, thus reducing re-equipping times. Another strength of the fully automatic DuraVision is seen when conducting serial tests on several work pieces, allowing even more valuable time to be saved.

CE protective housing (optional)
Maximum protection and maximum user-friendliness! — The DuraVision with CE protective housing complies with all international CE requirements. Because of the light barrier system it is not necessary to open any protective door to get into thetest area of the machine. Thus, user friendliness is increased without sacrificing safety. When the area between the light barrier is interrupted, the machine stops immediately all active movements and hardness tests. A status-LED indicates when the area between the light barrier is free again and the hardness tests can proceed without problems.

 |
|
Material and technology
Whether subjected to a 1 kgf or 3000 kgf test load, the rigid cast iron stand guarantees absolute test stability for the entire range of loads. By using precious components and materials we are also able to comply with North American safety standards (control unit ‘UL-listed’ for the highest standards of fire resistance for plastic covers).
|
|
| |
| |
 |
|
Overview camera (optional)
By using a Macro lens the camera produces a live image of the work piece, thus making it easier to set several test points and complex test rows. An unbeatable tool used in combination with the evaluation lenses!
|
|
| |
 |
|
Test unit
There are two ways of configurating the DuraVision test unit. Either with the standard swivel body or with an optional 6-fold-turret.
|
|
| |
 |
Motorised cross-slide
The cross slide’s broad ranges of x and y axis motion facilitate excellent, full automatic hardness testing. High definition makes it very easy to repeat actions and ensure positioning precision. |

Software that shows the way.
ecos Workflow technology shows the way ahead. Simple operation of even the most complex automation tasks is becoming increasingly important in the realm of hardness testing. The software takes over the task of directing the increasingly broad range of testing requirements and guarantees simple test object administration and lasting data security. The large proportion of software in the testing equipment allows ecos Workflow to make a decisive contribution to the performance capacity and quality of the overall product.
|
|
| |
|
|
Single measurements
This function allows you to set individual test points wherever you like. The test measurement can be started using the surface view or the overview.
Serial measurement
One or more test rows with positioning coordinates can be recorded. The measuring process can be started in the surface view or the overview.
Jominy tests (optional)
This is a module that conducts standardised or user-defined test runs on up to 9 Jominy specimens. The Jominy specimen holders are shown on the test anvil overview.
|
|
|
|
CHD/Nht/Rht measurements
For the performance of test series for CHD/Nht/Rht data of specimen according to standard. The test can be started directly from the surface view or from the overview. Additional core points of hardness can be defined separately for Nht measurements.

|
One lens - two enlargement levels
The sophisticated interplay between the lens system and software has enabled us to double the enlargement spectrum, while retaining the same excellent image quality.
Standard feature – no surcharge
The unique 2-step zoom is a standard feature of the entire DuraVision series, from basic through to high-end. This saves using additional lenses and thus reduces expenditure. |
|
 |
|
Perfect brightness setting
Manual light setting and the predefinition of various surfaces are things of the past. The powerful lens system ensures in combination with power LED technology the fully automatic determination of the ideal brightness level for every specimen or part.
|
|
|
Ensuring you find exactly the right spot
The ‘precise positioning’ software function allows the positions of all the test points to be accessed by the evaluation camera before the indentations are actually made. If you are not satisfied with the positioning of the individual test points before testing begins, they can very simply be moved and set to a new position. Above all, when testing the hardness on welded parts or sinter metals it’s an unbeatable tool.
|
|
|
|
Efficient pre-processing — write and load
XML files
To eliminate operator influence ecosWorkflow offers the option of predefining all relevant test limits, requirements and settings via externally produced XML files. These XML files can be written in an external programme such as Microsoft Excel, independent of the system or location. Stored XML files are loaded as patterns into ecosWorkflow by the operator. All relevant test limits, requirements and settings, such as the test method, test point coordinates, lens magnifications, conversions and additional info relevant to the work pieces are transferred to each work piece in question. This works with single and multiple work pieces without number limitations. The test results are saved to a selected location in a CSV or XML format. Commonly used statistics programmes can be used to process results accordingly.
|
|
 |
|
Impact protection – also without fixed work pieces
Beside the capacity to clamp the work piece according to established standards, the nose cone also provides ideal protection to lenses and indenters. If the two nose cone inserts are removed the lens and indenter are still protected, even without clamping.
Quick-change technology
If dismantling of the nose cone is still necessary it can be removed quickly thanks to the applied system similar to a ‘bayonet lock’.
A variety of clamping options
Depending on the geometry of the test piece the user can decide whether to use one or two nose cone inserts. Inserts can be changed in seconds – without the need to remove the entire nose cone.

|
|
Time-saving template mode
Work-pieces that have already been measured serve as master pattern. Their basic settings and parameters (i.e. test methods, conversions) can be applied to other work-pieces. When testing a new work-piece, these settings are automatically imported from the master Pattern. Pattern creation occurs automatically once a work-piece has been measured and archived. This tool is recommendable when testing work-pieces that all have the same parameters, such as tolerance levels, test methods etc. but may have varying descriptions. Conduct complex testing tasks with a minimum of steps.
Positioning above a fixed reference point
Several test points or rows can be fixed very simply to a defined reference point and saved as a pattern. Later, this template can be easily placed over the new work-piece and exactly positioned by rotation over the reference point.
|
|
|
Once saved — always available
If several work-pieces with the same test requirements are placed and tested on the cross slide, the DuraVision is able to show the full range of its skills. All test parameters are taken from the existing template and transferred to the new work-piece.
Work-pieces of differing heights
Not even the concurrent serial testing of numerous work-pieces of different heights presents a challenge for the DuraVision. The test nose cone is used to identify the height of the work-piece - with maximum collision protection.
|
|
|
|
Positioning with the panorama function (optional)
The Macro lens of the overview camera processes work-piece sizes of 100 x 125 mm. The real-time images of the overview camera enable both single measurement points and complex serial tests and pattern to be positioned with ease. The unique panorama function allows all the test points to be set at one go; even for larger work-pieces. The maximum work-piece size is only restricted by the limits of the motorised crossslide. The image of the work-piece from the overview camera can be inserted into test reports or archived in company networks.
|
|
|
Jominy tests (optional)
Jominy hardenability tests have never been so quick and easy to do! In the usual, familiar manner, the special ecos Workflow software module guides the operator step-by-step to the required result - even with Jominy tests. The operator has a choice of two Jominy testing options: standardised or user-defined: Standardised testing provides the operator with a choice between HV 30 and HRC test methods according to EN ISO 642 or ASTM A255 . All test parameters, such as the distances between test points, are predefined and guarantee to conform to accepted standards and norms. User-defined testing provides the operator with complete freedom of choice of Jominy tests on work-pieces according to individual requirements. All test methods are available and the operator can define his/her own pattern of test points and gaps. Furthermore, it is also possible to set up several parallel test rows on a test surface. When performing Jominy tests 1-fold and 3-fold sample holders can be used. The cross-slide can be equipped with a total of 3-sample holders, enabling up to 9 Jominy specimens to be tested concurrently. The result is portrayed with all relevant hardness scores in a clearly structured, standardised test report.

 |
|
6-fold turret
A true all-rounder. The turret can be used freely with various indenters and lenses depending on requirements making the DuraVision a true master of all trades. Hence, you can cover the full range of test methods and hardness values with just a single machine. Extremely fast: Not only does the 6-fold turret rotate at a great speed, it also recognises the shortest rotation way to the selected position. No collisions: Along with the nose cone, the turret, indenters and lenses are well protected from unwanted contact with the test piece.
|
|
|
CE-housing
CE conformity: There is innovative DuraVision CE protective housing available in order to conform to international CE regulations. Protection and user-friendliness: The test area of the DuraVision is easily accessible on the front of the transparent housing and made safe with a unique light barrier system. As well as guaranteeing maximal safety, also during a test run, there is always an unrestricted view of the test area. This uniquely open design ensures operation is both convenient and user-friendly, particularly when loading and unloading test objects.
|
|
|
|
Overview camera
Everything at a glance: The overview camera uses a Macro lens to generate an overview image (field of view 125 x 100 mm) of the work-piece. Single test points and complex test series can be placed on top of work-pieces in just a matter of seconds. Keep everything in view: Furthermore, the overview camera patterns, guiding lines, reference lines and resetting options for edges can be displayed and placed on top of the test piece. The image from the overview camera can also be saved and printed in test reports.
|
|
|
|
 |
|
Ring light
Optimal lighting for difficult surfaces: Particularly with Brinell tests on soft metals or poor test work-piece surfaces, the use of the powerful LED ring light ensures test indentations can be analysed ideally. Can be used with the lenses 2.5x, 4x and 10x. Rapid mounting: The ring light can be mounted and removed in seconds. Mounting the light could not be simpler.
|
|
|
Extended zoom 1:14
One lens – 14 zoom levels: This option has allowed the lens system to enable each lens to increase its performance to up to 14 zoom levels. You reduce expenditure on lenses while increasing the scope of test options!
