The Strain Gage SG-01 is the fiber optic equivalent of an electrical strain gage. The Strain Gage SG-01 can be mounted directly on the surface of a structure by means of an adhesive. In this way, the fiber sensor makes direct contact with the surface and therefore measures directly the strain at the surface. Installation of the optical Strain Gage happens preferably by means of the Sylex Strain Gage Installation Kit (SGK-01).The sensors are produced using a unique production process which ensures high strength of the fibers which in turns makes sure that the sensors have an excellent fatigue behaviour. Also the fiber coating is specifically developed for strain sensing applications and so it need not to be removed prior to installation of the sensors.
