In an exemplary method for installing a fitting on a conduit, a fitting body is provided with a threaded end portion, a neck portion extending rearward from the threaded end portion, and an internal conduit socket extending axially into the neck portion and terminating at a counterbore. A conduit is inserted in the internal conduit socket of the fitting body. A fitting nut is pulled up on the fitting body to grip and seal a conduit gripping device against the conduit. Relative axial displacement of at least first and second reference locations on the neck portion is detected to determine whether the fitting is in a first fitting assembly condition or a second fitting assembly condition different from the first fitting assembly condition. 本发明公开了在联接件中用于应变检测的系统和方法，在种用于将接头安装在导管上的示例性方法中，接头主体被设置有螺纹端部分、从所述螺纹端部分向后延伸的颈部部分以及轴向延伸到所述颈部部分内并且终止于埋头孔处的内部导管插座。将导管插入在所述接头主体的内部导管插座中。将接头螺母拉紧在所述接头主体上以抵靠所述导管来夹持和密封导管夹持设备；检测所述颈部部分上的至少第参考位置和第二参考位置的相对轴向移位，以确定所述接头处于第接头组件状态还是处于与所述第接头组件状态不同的第二接头组件状态。
