美国DAKOTA NDT螺栓应力测试仪BT2-DL

BT2-DL超声波螺栓张力监测器是我们螺栓产品的*新仪表。

简介
它融合了DAKOTA NDT BT1-DL螺栓张力监视器的所有伟大功能，在功能、硬件、速度和长度方面增加了一些好处。DAKOTA NDT BT2-DL超声波螺栓张力监视器非常准确地测量长度可达100英尺的紧固件，并在整体性能/功率方面得到更高提升！

当螺母和螺栓在负载下紧固在一起时，拧紧螺母的动作会增加施加在螺栓上的力，从而导致伸长。
通过使用超声波，螺栓张力监视器不受温度、摩擦或电阻因素的影响，这些因素会影响标准扭矩测量技术的精度-使达科他州BT1-DL螺栓张力监视器的精度在0.0001毫米（0.0001英寸）内。
使用仪表的USB接口以及可选的关闭附件，可以编程为在施加适当的负载时自动停止拧紧过程。

特点
显示和测量选项的范围包括：伸长率、载荷、应力和%应变、RF、校正、带限幅杆的大数字
温度补偿以对抗温度变化引起的测量不规则
数据存储能力：4GB内部内存
自动设置功能自动优化检测和调整显示
与数据端口一起工作的HI/LO警报耐受性限制
