Introduction: YZM-W Mixture Shrinkage Coefficient Tester is developed in accordance with T0720-1993 in "Highway Engineering Asphalt and Asphalt Mixture Test Regulations JTJ052-2000", using modern sensor technology, automatic control technology, and refrigeration technology. It is mainly used to test asphalt mixtures. The linear shrinkage of the sample under the specified time and temperature. This instrument is compact in structure and beautiful in style. It can use a microcomputer for fully automatic testing of the entire process. Mixture shrinkage coefficient tester is suitable for measuring the linear shrinkage coefficient of asphalt mixture. At the same time, it is also used for prismatic specimens cut from plate-shaped specimens formed by wheel rolling. The size of the specimen is 200mm±2.0mm in length, 20mm±1.0mm in width, and 20mm±1.0mm in height. The temperature range and cooling rate are based on Depending on the local climatic conditions, the temperature range usually used is +10℃~-20℃, and the cooling rate is 5℃/h. Technical index: Capacitive grid digital micrometer displacement sensor: stroke 0mm～10mm, resolution 0.001mm The temperature control resolution is 0.1℃, and the temperature control range is -30℃～room temperature; the temperature drop rate is 5℃/h ±1℃/h There is a 20×4 character LCD on the control instrument, and there is an RS232C serial port Power supply: 220V×50Hz Dimensions: 700×300×1000mm. Environment temperature: ≤35℃. Relative humidity: ≤85%. Power consumption of the whole machine: 2KW. Net weight of the instrument: 100kg Power supply voltage: 220v
