Description

Our new range of bench-top universal testing machines (UTMs) is designed for tensile and compression testing of materials, products and components.

These versatile universal testing systems are driven by our powerful and intuitive VectorPro™ testing software, making them easy to use for implementing quality assurance standards across all industries. The PC-driven model has the flexibility to run the test routines on your choice of computer hardware.

The OmniTest Touch model runs on a responsive touchscreen console driven by our powerful and intuitive VectorPro™ testing software. This fully integrated version makes a convenient and easy-to-use, standalone solution for implementing quality assurance standards across all industries.

The OmniTest Touch 0.5 kN, 1 kN and 2.5 kN models are part of the single-column range. They occupy minimal bench space and, at under 30kg, can be easily transported. The 2.5 kN model is particularly popular as a general-purpose tester whilst the 0.5 and 1kN models have extended column lengths making them particularly suitable for long-elongation, low-force tester.

Features

Test Frame

• The single-column OmniTest is available in 5 models with load capacities from 0.5 kN to 7.5 kN. They feature a precision ball screw that drives a moving cross head 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 cross head 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 minimize 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 2.5 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) adapters 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.

Loadcells

• 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 minimizes operator setup and configuration by quickly and easily sliding on a new loadcell, where its calibration characteristics are immediately recognized 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 optimize the accuracy of your test results.
• Thirteen different sensors, all measuring from zero, are available to cover the range from 2 N up to 2.5 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.
  • CSC can provide an ISO17025 cert when calibrated to the stand

Software

• 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. Personalized 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 analyze 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.

Grips and Fixtures

• 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) adapters that speed up the interchange of grips when you need to perform a variety of different tests.

Extensometry

• 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 traveled (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.

Safety Guard

• 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.

Specifications

• Accuracy
  • When calibrated as part of a system, accuracy is ±0.5% of reading down to 2% of range, suitable for use with Class 0.5 systems according to the requirements of ISO 7500-1. Eg, ELS 100 when measuring 10N is accurate to ± 0.05 N or when measuring 50N it is accurate to ± 0.25 N.
