美国DAKOTA NDT螺栓应力测试仪BT1-DL/BT2-DL
详细信息| 询价留言美国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。
