1、输出数据:电子拉力试验机试验结果输出结果可任意设置:最大力值、伸长率,抗拉强度、定力伸长、定伸长力值、屈服强度,弹性模量、最大试验力8项。这可以说是微电脑操作时,输出的最全面的结果。国外一些厂家的产品,一般可以输出这8项。国内有的厂家可以输出5-6项,有的厂家就只能输出最大力值,平均值,最小值六项。
1, output data: test results of electronic tensile testing machine
output can be arbitrarily set: the maximum force value, elongation,
tensile strength, elongation, elongation Changli value, yield strength,
elastic modulus, maximum stress test 8. This can be said to be the most
comprehensive result of the output of a microcomputer operation. In
general, some foreign manufacturers can produce these 8 items. Some
manufacturers in China can output 5-6 items, and some manufacturers can
only output maximum force, average value and minimum value of six items.
2、测试速度:市面设备有的在10~500mm/min,有的在0.001~500mm/min,前者一般使用普通调速系统,成本较低,影响精度;后者使用伺服系统,价格昂贵,精度高,对于软包装企业,选用伺服系统,调速范围1~500mm/min的就足够了,这样既不影响精度,价格又在合理范围之内。
2, test speed: some equipment in the 10~500mm/min market, some in
the 0.001~500mm/min, the former general use common control system, low
cost, affect the accuracy; the servo system, the price is expensive,
high precision, flexible packaging for enterprises, selection of the
servo system, the speed adjusting range of 1~500mm/min is enough, this
will not affect the accuracy. The price is in a reasonable range.
