    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
