电子扭角仪与电测扭矩配合使用，能测定金属材料的扭转力学性能，如剪切弹性模量（Ｇ）、扭转比例极限（Γ＿ｐ０．０１５）、屈服强度（Γ＿ｐ０．３）、及抗扭强度（Γ＿ｂ）、最大切应变（γｍａｘ）等，操作简便、效率高，不仅能测试样标距内的扭角，而且能在记录仪上直接绘出扭矩（Ｔ）－扭角（ψ）曲线，即用图解法按常规公式计算扭转性能各值。解决了扭转试验的电测方法问题。该方法克服了光学法的操作复杂、计算烦琐、重现性差等不足之处，为扭转试验实现电子计算机化打下了基础。
The electronic torsion angle meter is used in combination with the electric torque measurement to determine the torsional mechanical properties of metal materials such as shear modulus of elasticity (G), torsional ratio limit (Γ_p0.015), yield strength (Γ_p0.3) Intensity (Γ_b), the maximum shear strain (γmax) and so on, easy to operate, high efficiency, not only can test the twist within the standard gauge, and can be plotted directly on the recorder Torque (T) - torsion angle , That is, using graphical method according to the conventional formula to calculate the value of torsional properties. Solve the torsion test method of electrical measurement problems. The method overcomes the shortcomings of the optical method, such as complicated operation, cumbersome calculation and poor reproducibility, laying a foundation for the computerization of the torsion test.
