Introduction: CTE 101 optical high-temperature dilatometer is a kind of non-contact material expansion and contraction performance testing instrument. It adopts the non-contact displacement optical projection measurement technology to measure the linear displacement and deformation under high temperature and even ultra-high temperature (above 2500 ℃). The CTE 101 optical high-temperature thermal expansion instrument adopts the erected binding structure of the sample, which avoids the problem of the sample position movement in the unconstrained structure of the horizontal sample at home and abroad, which makes the test results more reliable and accurate. Optical high-temperature thermal expansion is the company's non-contact optical projection measurement technology of independent research and development products, making optical thermal expansion instrument more scalable, according to different requirements and technical indicators to establish the corresponding optical non-contact thermal expansion test equipment. Features: 1. CTE 101 optical high-temperature thermal expansion instrument, due to the use of optical projection method of this non-contact measurement method, and supporting the corresponding vacuum system, basically can achieve any temperature range and any atmosphere of thermal expansion material properties measurement can be measured The melting point of most materials, and can measure the thermal expansion behavior of the sample during chemical reaction and change. This feature is particularly important for the evaluation of thermal expansion properties of ablative composites. In order to improve the thermal expansion measurement accuracy below 300 ℃, the heating method can be used fluid heating methods, such as water bath, oil bath. 2. CTE 101 optical high-temperature dilatometer, which uses a restrained vertical sample mounting mode, avoids the influence of thermal stress on the sample position offset, and ensures the reliability and measurement accuracy of the test. The initial length of the sample is automatically measured and saved to facilitate the calculation of the coefficient of linear thermal expansion. 3. Bound vertical sample installation, combined with the corresponding transparent container, can achieve liquid, powder, paste and solid-liquid phase transition measurement process. 4. The optical projection method has a strong scalability, in addition to meet the linear displacement measurement needs, but also on the deformation and displacement measurements, this feature can be achieved material softening point, spherical, hemispherical and melting temperature and Viscosity measurement, with a high temperature microscope function. At the same time, the measurement of very large size samples can be achieved by expanding the beam. 5. Using a man-machine interface operating system, making the whole instrument a higher degree of integration easier to operate, test data is automatically stored in the U disk, you can also analyze the computer. 6 in different temperature range, the use of different temperature sensors for temperature measurement. 1400 ℃ following the use of thermocouple temperature sensor, the temperature will be higher infrared tester.
