This is a transducer to measure axial strain of tie-rod of a car. It is also suited to measure axial strain of tension rod used in aseismic reinforcement structure or in steel frame structure. Since frictional strain gauges are used in this transducer, installation is completed and it gets ready for measurement by merely pinching the rod with the transducer, without detaching the rod. There is no need of technical skill or complicated works for attaching strain gauges on the rod. It is applicable either to round rod or hexagonal rod by replacing the spacer and fixing bracket.
