HBS-3000V-Z Automatic Focusing Visual Brinell Hardness Tester
Vision technology
Embedded vision technology is to embed the vision chip directly into the instrument control system, and process and measure the image directly through the motherboard.It no longer needs the operating system, so as to avoid the crash caused by the driver through the operating system.
- Product introductionThe visual Brinell hardness tester HBS-3000V 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.

Objectivity: The visual system has objectivity, and the results of analysis are not affected by subjectivity.l High gray resolution: human eyes generally have 64 gray scales, and machine vision can reach 256 gray scales.l Embedded image technology replaces traditional measuring eyepiece, using camera + display mode, indentation image,direct display screen.l Type of Visual Chip: Industrial-grade Special High Definition Cameral Contrast, brightness, white balance and other adjustments are available.l Visual analysis model simplifies manual operation process, reduces operator fatigue, and makes measurementdata more intuitive and convenient.l Optimizing each link greatly improves the overall performance of the hardness tester and saves 50% ofthe time compared with the traditional hardness tester.Advantages of vision system relative to eyepiece measurementl 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.l 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.l It can provide two-dimensional simultaneous measurements of various measurement modes, simplify the measurement process and improve the measurement speed.l With rectangular tangent measurement methodl 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.Technical parameterModelHBS-3000VBrinell scaleHBW2.5/62.5、HBW2.5/187.5、HBW5/62.5、HBW5/125、HBW5/250、HBW5/750、HBW10/100、HBW10/125、HBW10/250、 HBW10/500、 HBW10/1000、HBW10/1500、HBW10/3000Test force62.5kgf、100kgf、125kgf、187.5kgf、250kgf、500kgf、750kgf、1000kgf、1500kgf、3000kgf612.9N、980.7N、1226N、1839N、2452N、4903N、7355N、9807N、14710N、29420NScale conversionHR、HV、HK est.Minimum measuring unit1µmTest force dwell time0-60sObjective lens and indenter switchingAutomaticFocusing methodAutomaticHardness testing range8-650HBWTotal magnification20XExecutive standardJJG150-2005，GB/T231，ASTM D-785，ISO6506Hardness indicationLCD displayDate outputBuilt-in printerPower supplyAC90-240V,50-60HzMaximum height of specimen250mmDistance from the center of indenter to body158mmShape size590*250*835Machine net weightAbout 140kg
- The Brinell hardness test method as used to determine Brinell hardness, is defined in ASTM E10. Most commonly it is used to test materials that have a structure that is too coarse or that have a surface that is too rough to be tested using another test method, e.g., castings and forgings. Brinell testing often use a very high test load (3000 kgf) and a 10mm diameter indenter so that the resulting indentation averages out most surface and sub-surface inconsistencies.
The Brinell method applies a predetermined test load (F) to a carbide ball of fixed diameter (D) which is held for a predetermined time period and then removed. The resulting impression is measured with a specially designed Brinell microscope or optical system across at least two diameters – usually at right angles to each other and these results are averaged (d). Although the calculation below can be used to generate the Brinell number, most often a chart is then used to convert the averaged diameter measurement to a Brinell hardness number.
Common test forces range from 500kgf often used for non-ferrous materials to 3000kgf usually used for steels and cast iron. There are other Brinell scales with load as low as 1kgf and 1mm diameter indenters but these are infrequently used.
