Pneumatic control unit for specimen grips

Function description

The pneumatic specimen grips emphasis is on fast, reproducible and, most importantly, parallel gripping. Full gripping force is available right from the start, so that the static jaws transmit the test speed directly to the specimen.

Simple extensions are used in combination with temperature chambers The pneumatic actuator is positioned outside the chamber.

Advantages

  • Whether you are testing sensitive specimens or specimens with short clamping lengths, these symmetrically designed grips guarantee optimum clamping.
  • When determining the exact nominal strain the grip-to-grip separation does not depend on specimen diameter. This minimizes set-up time.
  • Reduced weight plus a compact design simplify handling, ensure short heating and cooling times in the temperature chamber. and enable long travel.
  • Absolutely secure gripping right from the start of the test for specimens prone to light slippage.
