CAT-Technology is a multi-sample measurement technique and short for Centrifugal Adhesion Testing-Technology. It is used for the comprehensive determination of adhesive, bonding and composite strength. CAT employs a principle which is as simple as it is ingenious: centrifugal force is applied to up to 8 sample assemblies. The load increase is programmed by variation of rotor rpm. If the applied load exceeds the tensile strength of the sample assembly, the test stamp changes its position within a guiding sleeve.
The detachment of the TST (at the moment of rupture) is automatically detected and a position-coded IR-signal is send out of the turning rotor, transmitting the current rotor speed as well as the rupture time. The force at rupture and the tensile strength, either bonding or adhesive strength, is calculated and displayed on-line by LUM's measurement software SEPView.
All data is transmitted to the well-known and popular operating software SEPView, which automatically calculates and displays the critical force/strength of failure in real time.
Furthermore, it allows to analyze, compare & calculate statistics and combine results for up to tens of samples. Related data, as figures of fracture pattern, may be taken into account as well.
