OmniTest 0.5/1/2.5 เครื่องทดสอบแบบยูนิเวอร์แซล

The single-column OmniTest is available in 5 models with load capacities from 0.5 kN to 7.5 kN. They feature a precision ballscrew that drives a moving crosshead fitted with an ELS loadcell. Intuitive controls make the testers easy to use even for novice operators.

The construction of these single-column testers provides the necessary test space and crosshead travel for conducting elongation tests on your specimens up to 1186 mm. They deliver the strength capability for low- and mid-load break tests on a variety of materials and components. All models are ideal for the universal testing of samples to determine their tension, compression, flexure, shear and fracture characteristics.

Upper and lower safety limit switches minimise the risk of accidental damage caused by grips colliding. The 5 kN and 7.5 kN frames also feature a linear slide mechanism with excellent rigidity and strength to measure stiff samples. A protective bellow prevents dust and splintered materials from becoming trapped inside the machine.

For operator safety, a range of protective shields and enclosures is available on all machines, for situations where specimens may shatter or create projectiles upon failure.

Designed to apply tensile and compressive forces from 2 N right up to a capacity of 7.5 kN their high-quality construction, manufactured under ISO 9001 quality standards, ensures the ultimate in repeatable materials testing.

The base plate of the OmniTest is pre-drilled with threaded holes to connect a wide range of grips and fixtures. The OmniTest also uses quick-change (QC) adaptors that speed up the interchange of grips, for example when you need to perform a variety of different tests on different geometries of a material or finished product. 

The OmniTest UTMs take advantage of Mecmesin's range of high-resolution Enhanced Load Sensors (ELS) to precisely record tensile and compressive loads. 

When seeking to precisely measure forces across a wide range it is often necessary to use multiple loadcells. The dovetailed crosshead design of the OmniTest minimises operator setup and configuration by quickly and easily sliding on a new loadcell, where its calibration characteristics are immediately recognised by the software without any input from the operator.

These interchangeable ELS loadcells are compatible with any OmniTest test frame of equal or higher capacity and are chosen in order to optimise the accuracy of your test results.

Fourteen different sensors, all measuring from zero, are available to cover the range from 2 N up to 7.5 kN. This ensures that you have the optimum selection to meet all your tension and compression testing needs. Measurement accuracy is an outstanding ±0.5% of displayed reading.

Each ELS sensor is delivered as standard with its own calibration certificate traceable to national standards.

VectorPro delivers outstanding control of the motor, whilst simultaneously collecting data at 1000 Hz from the ELS loadcell and the displacement encoder of the frame.

The software is intuitive for both operators and managers. Personalised user accounts and a streamlined design mean that the workflow is simple and it is easy to create step-by-step test methods according to the precise requirements of your applications.

Access to the most commonly used test methods enables operators to move seamlessly from task to task, keeping training time to a minimum.

By plotting the data of force/displacement, stress/strain in real-time on a graph the operator can immediately identify exactly how the test sample is performing. Pre-set or custom calculations analyse the data to determine whether the specimen has met the pass/fail criteria. VectorPro includes standard calculations for Young's Modulus, Offset Yield, Ultimate Tensile Strength, Nominal Strain and a whole host of other materials characteristics. For product testing, it is possible to create custom calculations within a few seconds by using the drag-and-drop functions.

At the end of the test, the comprehensive reporting module within VectorPro enables the operator to issue a test report as a PDF. An extensive suite of template reports can be easily tailored to your internal or your customer's exact requirements and be automatically emailed to them as an HTML file. Test data can also be exported to Excel or to the network for further analysis.

VectorPro generates a clear audit trail with electronic-signature functionality - a must for medical and pharmaceutical clients seeking compliance to FDA 21 CFR Part 11.

Holding your test specimen in place without it slipping is essential to obtaining repeatable results. Mecmesin has designed a range of tension and compression grips to hold a variety of components. They include wedge grips, vice grips, peel jigs, bend jigs, compression plates and many more.

The base plate of the OmniTest is pre-drilled with threaded holes to connect a wide range of grips and fixtures. The OmniTest also uses quick-change (QC) adaptors that speed up the interchange of grips when you need to perform a variety of different tests.

The varying nature of specimen sizes and shapes often makes it necessary to design and produce a special grip. Mecmesin's team of design engineers can work with you to develop the best grip for your specimen and utilise our 3D printers to produce lightweight, precision fixtures to meet your needs.

When testing the extension or compressive deformation of a specimen it is often acceptable to measure the movement of the loadcell and grips, as defined by the crosshead distance travelled (known as 'grip separation').

This is taken directly from encoders situated on the ballscrews of the OmniTest. VectorPro software compensates for movement encountered within the loadcell and grip string (known also as 'Correction for Machine Compliance') but it cannot be as accurate as measuring extension directly upon the specimen. In some test applications, this is perfectly acceptable and does not impact the relevance of the measured results.

For materials requiring extension measurement to be taken directly on the specimen, a range of contact extensometers is available for use with the OmniTest. The range of contact extensometers include short-travel extensometers suitable for rigid materials (eg hard plastics and metals) through to long-travel extensometers designed for highly elastic materials (eg rubbers or soft plastics), simply select the model which best suits your material's characteristics.

Our systems can be supplied with a standard safety guard to prevent access by the operator to the testing area whilst the test is in progress. These have a rigid metal frame with integrated polycarbonate panels to allow the operator to view the test area from outside. Hinged doors are fitted with switch-activated interlock mechanisms that prevent system operation when open.

Guards for single-column test stands are provided on a solid metal platform, with location holes available for securing to a workbench, to ensure complete stability.

Safety guards are supplied with CE marking and a Declaration of Conformity in accordance with several harmonised standards of the Machinery Directive 2006/42/EC, including BS EN ISO 12100:2010, BS EN ISO 14120:2015, BS EN ISO 14119:2013, BS EN ISO 13855:2010, BS EN ISO 13857:2008, BS EN ISO 13849-1:2015.

If the risk assessment for your application indicates protection from egress is also required, our engineers can offer a custom design to meet your needs.
