    美国DAKOTA NDT 螺栓应力测试仪BT1-DL

    BT1-DL 使用超声波精确测量紧固件的伸长、时间(纳秒)、载荷、应力和%应变。
    采用先进的超声波皮射技术 ,能快速地测量出螺栓紧固后的应力和应变 ,

    具有使用方便、显示直观、 便于携带等特点。


    螺栓应力测试仪以其*的构思、 强大的功能和测量广泛的应用于航空航天、 卫星制造、电力设备、 建筑桥梁和石油化工等领域。




    简介
    DAKOTA NDT BT1-DL 螺栓张力监视器
    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.
    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
