To suit your materials testing requirements the OmniTest range is available as 2 models of single-column materials tester (5 kN and 7.5kN) and as 3 models of a dual-column tester (10 kN, 25 kN and 50 kN).
They have been designed for versatility and ease-of-use thus appealing to users of varying skills and experience. They all fit comfortably on your bench-top, making them ideal for use in QC and R&D laboratories.
All OmniTest models are controlled by VectorPro-MT software running on a PC. They deliver both consistency and reliability by controlling the key test parameters of stress/strain, force/displacement and speed/load rate.
Whether you need to know the Young's Modulus, Offset Yield, Ultimate Tensile Strength or a whole host of other materials characteristics, the OmniTest has it covered for you.
The single-column OmniTest testing system comprises five key elements:
The single-column OmniTest materials testers feature a precision ballscrew with linear slide mechanism, which drive a solid crosshead to which an ELS loadcell is attached. This ensures excellent rigidity and strength whilst their intuitive controls make them easy to use, even for novice operators.
The construction of these single-column materials testers provides the crosshead travel required for conducting elongation tests up to 650mm whilst also delivering the strength capability for mid-load break tests on rigid materials. All models are ideal for general purpose testing of specimens to determine their tension, compression, flexure, shear and fracture characteristics.
Protective bellows guarantee that dust and splintered materials cannot become trapped inside the machine. Upper and lower safety limit switches minimise the risk of accidental damage caused by grips colliding. For operator safety, a range of protective shields/enclosures is available in situations where specimens may shatter or create projectiles upon failure.
Designed to apply tensile and compressive forces from 2N 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.
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 ensures the operator minimises set-up time by quickly and easily sliding on a new loadcell, which is automatically recognised by the software.
The base plate of the OmniTest is pre-drilled with threaded holes to directly accept a wide range of grips and fixtures. It also accepts the quick-change (QC) adaptors which speed up the interchange of grips when you need to perform a variety of different tests on different geometries of material.
Make use of your own PC to run its software and take advantage of its versatility to make it your ideal choice for materials testing up to 7.5 kN.
The ELS range of high-resolution, precision loadcells is specially adapted to the OmniTest. They are fully interchangeable and plug into the frame, where their calibration characteristics are immediately recognised by the tester without any input from the operator.
Fifteen 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™-MT software is at the heart of the OmniTest materials testers. It is recommended for use on a Windows 10 platform computer and delivers outstanding control of the motor, whilst simultaneously collecting data at an impressive 1,000 Hz from the ELS loadcell and displacement encoder of the frame.
VectorPro-MT has been designed to be purely intuitive for both operators and managers. Its streamlined design keeps the workflow simple and allows step-by-step test methods to be quickly and easily created according to the exact requirements of your testing procedures.
Personalised user accounts give access to the most commonly used test methods ensuring operators move seamlessly from task to task, keeping training time to a minimum.
By plotting stress/strain data in real-time on a graph the operator can immediately identify exactly how the test material is performing. Preset materials testing calculations are used to analyse the data to determine whether the specimen has met the pass/fail criteria. Use the power of VectorPro-MT to calculate Young's Modulus, Offset Yield, Ultimate Tensile Strength, Nominal Strain and a whole host of other materials characteristics.
At the end of the test, the comprehensive reporting module within VectorPro-MT allows the operator to issue a test report as a PDF, which is tailored to your customer's exact requirements and can be automatically e-mailed to them. Additionally, the data can be exported to Excel or to the network for further analysis.
The database architecture behind VectorPro-MT provides a clear audit trail with electronic-signature functionality - a must for medical and pharmaceutical clients seeking compliance to FDA 21 CFR Part 11.
When testing the extension or compressive deformation of a specimen it is often acceptable to measure the movement of the loadcell & grips, as defined by the crosshead distance travelled. This is taken directly from encoders situated on the ballscrews of the OmniTest. VectorPro MT 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.
For materials requiring extension measurement to be taken directly on the specimen, a range of contact extensometers is available for use with the OmniTest. From short-travel extensometers suitable for rigid materials (eg. hard plastics & metals) through to long-travel extensometers designed for highly elastic materials (eg. rubbers, soft plastics), simply select the model which best suits your material characteristics.
Grips & fixtures
Holding your specimen material 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 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.
