YSML-2015型引伸计法杨氏模量测定仪(高精度数显式),是供各个大学物理教学实验中心使用的一种新型教学仪器,通过该仪器可以准确测定金属丝的杨氏模量。该仪器测量精度≤1%,满足国家标准GB/T228.1-2010《金属材料拉伸试验第一部分:室温试验方法》的要求。该仪器采用拉力传感器,变型传感器(引伸计)和高精度测量数显表组成,可对金属丝拉力和变形伸长量数显直接读数。测量数据直观方便,准确性好,重复性好,可靠性高。与教科书中常见金属的杨氏模量标准数据保持一致。
YSML-2015 extensometer method Young’s modulus tester (high-precision digital display), is a new type of teaching instrument for each university physics teaching experiment center, through which the instrument can accurately measure the Young’s modulus . The accuracy of the instrument ≤ 1%, to meet the national standard GB / T228.1-2010 “tensile test of metallic materials Part I: room temperature test method” requirements. The instrument uses a tension sensor, a modified sensor (extensometer) and high-precision measurement of digital form can be measured directly on the tensile strength and deformation of the wire number. Measurement data intuitive and convenient, good accuracy, good repeatability, high reliability. Consistent with the Young’s modulus standard data of common metals in textbooks.
