Brief introduction of main uses and functions:
The CST-50 type Charpy projector is designed to meet the requirements of GB/T229-1994 for metal Charpy impact testing. It is specifically developed to assess the quality of V-type and U-type gaps in impact test specimens. This optical instrument utilizes projection methods to magnify the contours of the V and U gaps on the test samples by 50 times, projecting them onto a screen. By comparing the projected gaps with standard models, it determines whether the tested samples meet the required gap standards. Its advantages include ease of operation and intuitive comparison.
Working principle:
The projector's light source emits light, which is directed through a condenser onto the object being measured. The magnified outline of the object is then projected onto a screen using an objective lens. With the instrument set for single projection as needed, the light passes through a series of optical elements to illuminate the worktable. Through further optical transformations, the notch outline of the tested sample is clearly projected onto the screen. This process results in a positive image that accurately reflects the position of the actual sample on the projection screen.
