The aerodynamically designed compound pendulum provides
maximum rigidity in the direction of the impact and virtually eliminates any windage losses. Pendulum capacity is easily changed by adding on any one of seven optional weight sets.
The energy absorbed in breaking the specimen can be configured in SI, metric, or English units and is determined by an optical encoder mounted on the shaft of the machine and is based on the latched height of the hammer (relative to the zero potential energy point), the maximum post-impact height of the hammer, and the frictional losses of the machine. Energies of less than 0.03% of the pendulum capacity can be resolved and this resolution is vastly superior to dial type displays and other currently available displays.
The IT 503 is supplied as standard with a “low blow” feature which provides a convenient and reliable means for releasing the pendulum from a lower than usual height, so allowing testing at lower impact velocities and energy levels.
Additionally, the model IT 503 is supplied with all necessary interlocked safety shielding to protect the operator and bystanders from the broken samples.
To make impact testing on plastics easier and more flexible, the machines can be connected to a pc running Tinius Olsen’s Horizon software for data capture and analysis.
The standard capacity range of the machine using the compound
pendulum is from 2J to 2.82J; this can increased to a maximum of 25J on the compound pendulum, using different weight sets to take you to capacities of 5J, 50in.lb, 7.5J, 100 in.lb, 15J, 200in.lb, and 25J. Outside of this range, the compound pendulum needs to be replaced by individual pendulums.
Optional pendulums available have capacities of 0.5J, 1J, and on the other end of the spectrum, 50J. The primary difference between the IT503 and the IT504 is that the model IT504 is supplied without the interlocking safety shielding.
