Pneumatic Control Unit for Specimen Grips

Function description

The load-reduction curve with 180° deflection gently reduces the tensile force before the clamping point. Pneumatic clamping ensures constant gripping force with easy, reproducible adjustment. The specimen is held securely and jaw breaks during the test are avoided.

Advantages

  • Secure holding of the specimen ensures reliable test results, even with specimens prone to shrinkage.
  • High specimen throughput thanks to quick specimen insertion and exact centering with insertion aid and guide groove.
  • Fast, easy two-handed specimen change - grips operated via foot control unit.
  • The load-reduction curve ensures gentle gripping with no jaw breaks.
  • The symmetrical weight distribution of the grips ensures accurate force measurement.

Pneumatic Control Unit for Specimen Grips

The closing force of the pneumatic grips can be steplessly set via a pneumatic control unit, which ensures safe gripping of a wide range of different materials. The opening and closing of the specimen grips can be controlled by foot switches or via the remote control of the materials testing machine for greater operating comfort.
