Description

Technical Field

[0001] This utility model relates to the field of metal linear expansion coefficient detection technology, specifically a multi-channel metal linear expansion coefficient tester. Background Technology

[0002] The basic principle of the coefficient of thermal expansion test is to calculate the coefficient of thermal expansion by measuring the change in length of the material during temperature change. Different test methods can be used depending on the material, such as linear coefficient of thermal expansion test and volumetric coefficient of thermal expansion test. The linear coefficient of thermal expansion refers to the change in length per unit length of the material when the temperature changes, while the volumetric coefficient of thermal expansion refers to the change in volume per unit volume of the material when the temperature changes. The coefficient of thermal expansion test requires the use of specialized testing equipment, including high-temperature furnace, displacement sensor, data acquisition system, etc.

[0003] Currently, when conducting experiments to test the coefficient of thermal expansion of metals, it is impossible to accurately control the heating temperature of the metal wire, which leads to errors in the test data and prevents the electrical analysis of the experimental data on the coefficient of thermal expansion. Furthermore, most traditional metal linear expansion coefficient testing devices are single-channel, which greatly reduces the efficiency of the metal linear expansion coefficient test. Therefore, a multi-channel metal linear expansion coefficient testing instrument is needed to improve the above-mentioned problems. Utility Model Content

Inside the experimental chamber 201, a channel wire groove 203, a heating plate 204, a displacement sensor 205, and a temperature sensor 207 are fixedly connected. The temperature sensor 207 is equipped with an upward resistor. A cover plate 202 is installed on the top of the experimental chamber 201. Detection and control component 3 includes a control box 301. A temperature controller 302 is fixedly connected to the side of the control box 301.

The temperature controller 302 has temperature regulation capabilities and can adjust the ambient temperature according to a preset temperature. Combined with the heating plate 204 and the temperature sensor 207, it can provide a suitable experimental environment for heating the metal wire. It can sense changes in ambient temperature and react quickly. Parameters such as the temperature range, humidity range, and test time for the metal wire expansion coefficient experiment can be adjusted according to actual needs.

[0027] The system includes two heating plates 204, four channel grooves 203 and displacement sensors 205, a water level line 206 fixedly connected inside the experimental chamber 201, a temperature digital display screen 303 fixedly connected to the side of the temperature controller 302, temperature adjustment buttons 304 on the side of the temperature controller 302, an expansion coefficient display screen 305 fixedly connected to the side of the control box 301, indicator lights 306 and physical buttons 307 on the side of the control box 301, and an electrically connected processor 310, data acquisition unit 311, data analysis unit 312, and storage unit 313. Multi-channel detection allows simultaneous detection of multiple points or channels, significantly reducing detection time and improving efficiency. Utilizing multiple independent sensors or detection devices, multi-channel detection provides more accurate and reliable results. By reducing the number of detection devices and sensors used, multi-channel detection lowers costs. Furthermore, improved detection efficiency and accuracy reduce defective products, lower product scrap rates and maintenance costs, thereby further reducing production costs.

[0028] In this embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 As shown, the main body 1 includes a support frame 101.
