For metal tensile testing, beyond the wide range of clamping systems mechanical wedge type grips are used frequently. Hegewald & Peschke MPT GmbH offers these holding fixtures up to a load of 400 kN. A notable highlight is the integrated adaptation system for compression plates, bending benches, power analysers and so on. A time consuming change of the test equipment during changing setting of tasks is avoided thereby.

Fast and slide-safe tensile tests according to national and international standards, on worked and non-worked flat and round test pieces of metallic and nonmetallic materials of all tensile strengths. Suitable for sheet, plate, rod, section, strip, straight and curved wire, wire ropes, lace, cables, round and flat test pieces, round and section pipe, technical textiles, fleece, plastics, rubber, leather, compound materials, fabric, grates.  

The further development of high temperature materials, as used in the construction of turbines or boilers for power stations or for aircraft engines, is a central focus of material research.

Temperature and climate chambers provide the possibility of material and component testing under defined environmental conditions. The simulation of temperature and humidity whilst applying distinctive loads to the specimen is of great importance in material research, developing new materials and also for industrial quality assessment.

Measurements with the video extensometer track measuring marks applied to the sample surface. The video extensometer is ideal for samples that are very sensitive to indentations and thus induced cracks. It is used for tensile and compression tests on all types of plastics, metals, rubber and composite materials.

Manual clip-on extensometers for fine extension measurement (E-modulus, Rp) or long-distance extensometers for fine and coarse extension measurement (E- modulus, Rp, A). The user can choose among manual or automatic opening and closing of measurement arms. From the E-modulus up to specimen fracture all elongation values can be recorded.

The non-contact linear expansion measurement allows the automatic determination of the initial gauge length (L0). The optical system does not influence the measurement with knife edges or its own weight. Laser and video extensometers are used. 

The laser extensometer is used for non-contact measurement of strain or compression of test specimens under uniaxial load. Two measuring marks are applied to the sample before the test. The laser extensometer scans the measuring range with a visible laser beam and automatically determines the reference length. The positions of the measuring marks are recorded throughout the test. The software calculates the length change and elongation from the temporal progression.

Each machine model of the INSPEKT series can be equipped with a transparent Makrolon safety door. It is possible to slide the door to the left or to the right side. It exists the possibility to select between manual handling or electrical locking system. An electronic status monitoring provides an indication to the software program, whether the safety door is open or closed. The software program sets, whether the system is operative or blocked. The industrial safety door inquiry is disengageable with a key switch.

By using the changing device with linear roll guides the changeover times for the realization of different testing tasks at one machine can be reduced to a minimum. The accessory equipment can be moved uncomplicatedly, safely and manual easily into the test room. Equipment, which is currently not used, is placed in parking positions behind the testing machine. The changing device is e. g. suitable for different high temperature kilns, extensometers or temperature and climatic chambers.
