The tension rod is composed of a tension detection module, tension control module, tension barrier, and related accessories. It is a device that can detect, analyze, and output alarm signals for the tension rope's tensioning, relaxing, and breaking states. The tension rod is equipped with built-in sensors to detect changes in tension, analyze and calculate the change in length of the measured barrier, thereby determining the barrier's status.

The tension rod assembly consists of a tension rod, tension spring, range gauge, and swivel base.
