| Machine control |
- Vertical displacement of the roller segment by brushless motor measured directly by encoder to verify in real time the specimen thickness
- Machine fitted with sensors to confirm the mould in position and for the automatic set-up of the horizontal travel |
| Firmware |
Set up of compaction procedure with displacement control with load, density or thickness limit.
- Selection, customization and storing of test parameters
- Customization of the compacting procedure to be saved and recalled from the data base
- Graphic display of roller vertical displacement vs. number of passes
- Possibility to pre-set a load threshold to start compaction at the contact of the sector head with the specimen |
