0911472255The Automatic Brinell Hardness Tester, incorporating state-of-the-art Closed-loop Load Cell technology, is the ultimate solution for demanding material testing requirements in modern industrial environments. Unlike traditional dead-weight testing machines that are highly susceptible to friction, inertia, and mechanical wear, the advanced closed-loop system engineered by TAIZHOU EBPU continuously monitors, controls, and compensates the applied test force in real-time via an integrated central microprocessor and micro-encoder. This guarantees absolute force application accuracy, completely eliminates mechanical force overshoot, and elevates the repeatability of hardness measurements to the highest industrial benchmark.
The instrument excels with its fully automated (Full-Automatic) operational workflow and an exceptionally wide testing load range. It integrates multiple standardized multi-load testing stages, allowing seamless adaptability across various inspection procedures—from soft metals and non-ferrous alloys to coarse structural unhardened steels and large cast iron components. The most significant innovation centers on the intelligent digital optical measurement system, which seamlessly combines a high-resolution CCD camera with professional digital image analysis software. Upon completion of the load dwell cycle, the machine automatically executes autofocusing, boundary recognition of the Brinell indentation, diameter calculation, and instantaneously projects the definitive HBW hardness value onto the control screen. This eliminates the necessity for operators to manually measure indentations through traditional optical microscopes, drastically mitigating subjective human reading discrepancies.
Furthermore, this premium testing machine boasts advanced smart data management and comprehensive quality control (QC) report generation capabilities. Complete inspection data packages—encompassing specimen ID numbers, target test force, dwell times, indentation diameters d1/d2, measured hardness values, and comprehensive statistical summaries (Max, Min, Average, Standard Deviation)—are stored directly in the internal database or easily exported to external computers via USB or RS232 interfaces. Reports can be generated in universally accessible formats such as Excel, Word, or PDF. This critical feature enables enterprises to streamline their inbound/outbound QA/QC protocols, facilitating seamless technical record-keeping and formal product handovers to domestic and international clients. This equipment is widely deployed across third-party inspection centers, heavy-duty forging shops, metallurgical foundries, shipbuilding yards, structural steel fabricators, and advanced materials research laboratories.
