Universal Testing Machines

The materials testing machines of the smarTens (single or 2-spindle machine up to 30 kN) or proTens (2-spindle machine up to 250 kN) series are suitable for many different applications and uses for demanding testing tasks in the field of quality control as well as for R&D. The extensive range of accessories and the modular design allow a wide variety of expansion options, even at a later date or if the machine configuration has to grow with the tasks placed on it. The proTens series in particular is available in various test chamber dimensions (height, width) and can therefore be optimally configured for your testing task.

  • highly accurate force measurement by means of DMS load cell
  • compact workplace design
  • designed for standing as well as sitting activities due to very flat lower crossbar and lateral arrangement of the electronics
  • Large machine base plate for the adaptation of accessories and the storage of tools or samples
  • Variable speed upto 1200 mm/min.

Universal Testing Machines series „smarTens 20/30“

Twin ball screw drive universal testing machine for loads up to 20 or 30 kN

The smarTens 20 / 30 kN materials testing machines were designed for standard and routine tests. These universal testing machines are used in quality assurance and are characterised by a particularly attractive price/performance ratio. The smarTens 20/30 is suitable for tensile, compression, peel and bending tests on different materials. In combination with the ergonomic design and the new brushless drive concept, a safe and fast measurement with easiest operation is guaranteed both in rough production environments and in sterile labo

Features / Equipment:

Our material testing software has been developed in a modular design and consists of a comprehensive basic software. This allows simple but also complex testing tasks to be configured in a standard-compliant or customer-specific manner. A large number of templates or pre-configured test parameter sets are available for standardised and standard-compliant test tasks. In addition and for the individual creation of test cycles, a freely programmable software (block program creation) with the following features is available:

  • Free programming of a sequence control for static or dynamic tests
  • Individual definition of test parameters including calculation / display of test results (force, displacement, strain or any other measured values such as temperature, weight, etc.)
  • All test results can be converted with arithmetic formulas.

The integrated test wizard can be used to configure the test sequence individually, so that the user only has to operate the necessary input windows, receives supporting information and can work through his tasks purposefully. Our software works under Microsoft Windows® and guarantees „Microsoft Office® compatibility", i.e. all results can be exported to other applications such as Access®, Excel®, ASCII-file or other SQL applications. The integrated report generator allows individual report generation including graphical display in single or series mode. The software is available in different languages.
