Motorized Pendulum Impact Tester

Impact test determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material’s toughness and acts as a tool to study temperature-dependent nature of brittle-ductile transition

UTCI series motorized pendulum impact testers are fully automated and high performance devices which are ideal for testing metals according to Charpy and Izod standards up to capacities of 450J.

U-type pendulums are suspended on a sturdy steel pedestal which is designed to be attached to a concrete base or a strong floor. Pendulum is driven by an electric motor and an electromagnetic clutch system. The fall of the pendulum is initiated with a latch mechanism so that the fall is sudden and unaffected from any friction losses.

After the test, the pendulum is automatically captured and returned to the starting position. Angle, therefore position readings of the pendulum are done by a rotary encoder and the data is processed by a colored touch screen control unit to display absorbed energy values.

Utest impact testers can run with both user command and door triggered modes and in both modes the automation of the device together with the safety cabin is designed to prevent any unforeseen accidents and user injuries. Door triggered testing mode enables the fast and continuous testing for temperature sensitive tests and user command mode provides for more control for the operator.

Heat treated anvils and the striker are replaceable for both to be changed because wear caused by the long term use and to allow 8 mm radius striker to be mounted on the pendulum.

Typical field of use: Universities, laboratories of the institutions, automotive and aero companies, R&D Labs, steel manufacturers, etc.

Referance Specimen Sets for Indirect Verification are certified by DAkkS and include 5 identical specimens.. The Testing Machines are supplied complete with safety cabin, izod striker (UTCI-0558), charpy impact strikers (with an 2 mm radius and 4 mm radius) and a tongs for centering charpy specimens (UTCI-0557).
