KYOWA is a leading company contributing the world by offering stress measuring equipment.KYOWA provides the way to know the strength of structures.

Strain/stress measurement provides criteria for knowing the strength of structures and is indispensable to ensure the sufficient strength and safety of the equipment and structures used under severe conditions. Strain is the deformation a material shows when elongated or contracted in proportion to an applied force. A strain gage detects the strain as an electric signal.
