JBWZD-300C    Microcomputer Controlled Automatic Low Temperature Pendulum Impact Testing Machine

I、Overview

This machine is an instrument for testing the impact resistance of metal materials under dynamic load. It can continuously do a large number of metal impact tests. It adopts full automatic control. The control system adopts imported programmable controller (PLC) to control the whole process of swing taking and impact test through microcomputer software program. Display impact absorption energy, impact toughness, pendulum rotation angle and print test report, etc. The utility model has the advantages of simple operation, safety, reliability and high work efficiency. The machine is equipped with protective net cover, which provides conditions for users' safe operation. It is not only a necessary testing instrument for metal material manufacturers and quality inspection departments, but also an indispensable testing instrument for new material research in scientific research institutions.
