Automatic Focusing Vision Brinell Hardness Tester AuToBrin-3000Y is mainly used to measure the Brinell hardness of materials. The latest frame structure design, the high precision step-control system and the more intuitive measurement method are adopted. The structure is more stable, the control accuracy is higher, the time and effort are saved, and the accuracy is improved by an order of magnitude.The machine adopts electronic control automatic loading, computer software programming, high-power optical measurement, photoelectric sensor and other systems, and adopts high-precision step control technology to ensure that the load of test force does not overshoot. By manually fitting the indentation edge, the Brinell hardness is automatically calculated and displayed on the LCD screen. The reading is accurate and the operation is convenient.

Vision System Characteristics
◆ Objectivity: The visual system has objectivity, and the results of analysis are not affected by subjectivity.
◆ High gray resolution: human eyes generally have 64 gray scales, and machine vision can reach 256 gray scales.
◆ Embedded image technology replaces traditional measuring eyepiece, using camera + display mode, indentation image, direct display screen.
◆ Type of Visual Chip: Industrial-grade Special High Definition Camera.
◆ Contrast, brightness, white balance and other adjustments are available.
◆ Vision analysis model simplifies manual operation process, reduces operator fatigue, and makes measurement data more intuitive and convenient.
◆ Optimizing each link greatly improves the overall performance of the hardness tester and saves 50% of the time compared with the traditional hardness tester.
Advantages of vision system relative to eyepiece measurement
◆ There is no visual error when measuring directly on the surface that needs to be measured. The hardness tester of traditional structure is measured by eyepiece. The calibration line and indentation are not on one plane. Under different angles of view, the calibration position and indentation position will produce visual difference, which will lead to different angles of view and different results of personnel measurement.
◆ High measurement accuracy: there is no problem of mechanical eyepiece error. The calibration resolution of mechanical eyepiece helical microstructures is about 10 m, and there is mechanical backlash, so it is necessary to define the measurement method strictly. Pixel spacing of image sensor in vision system is 7.5 m, which has high precision and good measurement consistency.
◆ It can provide two-dimensional simultaneous measurements of various measurement modes, simplify the measurement process and improve the measurement speed.
◆ With rectangular tangent measurement method.
◆ No visual fatigue, reduce the measurement of labor intensity. The vision system adopts 65K true color TFT LCD screen, which is comfortable to observe and not fatigued, and can be measured by many people at the same time.
