Product Description

Product DescriptionIntelligent Low-Temperature Asphalt Ductility TesterThe LYY-7G Computerized Low-Temperature Asphalt Ductility Tester is designed and manufactured in accordance with the specifications outlined in JTG3410-2025 and is suitable for determining the ductility of asphalt. The instrument's refrigeration system utilizes a complete, high-quality air conditioning unit from a renowned manufacturer. Equipped with a 12-inch industrial computer, it employs optimized PID and fuzzy control algorithms to achieve a temperature control accuracy of ±0.1°C. The unit features an external display panel and external control buttons; its stretching mechanism operates smoothly, offering highly precise speed control that completely eliminates low-speed vibration. The system supports tensile force measurement, enabling tensile testing of modified asphalt, and includes capabilities for real-time graph display, data storage, and printing. Most models within this product series feature serial communication ports and offer optional networking capabilities, providing various data upload methods such as direct serial connection, direct writing to remote databases, and data interaction via Web Service/HTTP interfaces.Features1 Dual internal and external water circulation system: internal loop maintains constant temperature with minimal water ripples and stable temperature control.
2 High-resolution stepper motor combined with a soft-start algorithm ensures low vibration, making it suitable for testing modified asphalt.
3 Three-channel 500N force measurement system, capable of recording both force curves and peak values.
4 Preset tensile speeds of 10/50 mm/min, with customizable options; return speed reaches up to 600 mm/min.
5 Imported linear guides and ball screws ensure smooth and stable tensile motion.
6 0.1 mm displacement accuracy with automatic, precise return-to-home functionality.
7 Intelligent temperature control system utilizing a combination of PID and fuzzy logic algorithms.
8 Built-in LED lighting and a transparent hinged lid allow for clear observation of the test process.
9 Intuitive operation via a combination of physical buttons and a touchscreen interface.
10 Features a 12-inch industrial tablet PC running specialized software, capable of generating and printing A4-format test reports.
11 Unlimited data storage capacity with multiple data retrieval options.
12 Includes a standard-issue micro-printer for immediate report output.
13 Optional industrial camera available for real-time monitoring of the test specimen.
14 Free cloud service provided for permanent, secure cloud-based data storage.
