Srew Withdrawal Force Meter adalah indikator kekuatan, kepadatan, dan modulus geser kayu. Oleh karena itu, Fakopp Enterprise telah mengembangkan meteran gaya penarikan sekrup portabel. Diameter sekrup yang diterapkan adalah 4mm, panjang ulirnya adalah 18 mm. Gaya penarikan sekrup adalah parameter lokal, tetapi memilih lokasi yang representatif pada balok, dapat memberikan informasi yang berguna dalam evaluasi struktur kayu
usage instruction
- Drive the screw into the wood material, perpendicular to its surface.
- Connect the cable of the force transducer to the display unit R320.
- Switch on the unit by pressing the “ON” button for 3 seconds.
- Select the Peak hold function.
- Start the screw withdrawal process by placing the mechanics over the screw. Catch the screw head by the fork of the force transducer.
- Slowly turn the handle clockwise until the screw is removed. The speed of the withdrawal should be approximately 0.5 mm/s.
- Record the maximal force value and press the “Max” button before the next test to reset the display.
