CST-50 Impact Sample Projector

1.Brief introduction of main uses and functions  

CST – 50 type charpy projector is my company according to the actual needs of the masses of users and GB/T229-1994 in metal charpy impact test method for impact test specimen gap requirements and the development of a dedicated to testing the charpy V type and U type gap processing quality of optical instrument, this instrument is to use optical projection method will be the impact of the test sample V and U gap contour after magnified 50 times projected on the projection screen, and the impact of the projection screen sample V and model contrast figure, u-shaped gap standard to determine whether the gap of the samples tested to be qualified.Its advantage is easy to operate, comparative intuitionistic.

2.Working principle

The light emitted by the light source of the projector illuminates the object to be measured through a condenser, and then projects the magnified outline of the object to the projection screen with the objective lens.

As required, the instrument is illuminated by a single projection. The light source is projected on the worktable through a series of optical elements, which, through a series of optical elements, will clearly project the notch outline of the tested sample onto the projection screen.The object is transformed into a positive image through secondary magnification and reflection. The figure seen on the projection screen is consistent with the position of the actual sample.
