Product Description :

JBW-H series of instrumented Impact Testing Machine testing machine for automatic control, raise pendulum, hanging pendulum, the shock and braking are all electrical control operation, and can be placed in the thrust sample automatically after raising ready for the next impact Test, by varying impact pendulum, can provide the biggest impact energy: 150J.300J.450J.750J.

The impact Tester adopts data acquisition system, 0321 the voltage signal into digital signal, increased the data storage and computer, the collected signal as impact time and impact - displacement, displacement of time and energy - time curve, the stress of the given image to be thrust sample and the deformation process, the impact test are making a big push, comprehensive, thoroughly improve to the level equal to the current electronic tensile test, impact test is from the primitive state of leap into the advanced ranks of digital test instrument.

Test data acquisition, automatic recording and output by the measurement and control system. Dial the adjustment is convenient Testing machine Settings, use pointer calibration data compared with the data from the detection system, in order to verify the reading of the dial and energy testing system accuracy deviation of reading.
