Embeddable Optical Strain Sensor

The os3500 Embeddable Strain Sensor measures average strain over the length of the gage while providing integrated temperature compensation.

Product Description

The os3500 Embeddable Strain Sensor measures average strain over the length of the gage while providing integrated temperature compensation. The os3500 is intended exclusively for embedding in concrete structures. Disk ends form a solid bond to surrounding concrete or grout.

A rugged, stainless steel body, ruggedized cables and optional connector protection fittings make the os3500 suitable for harsh environments. Two fiber Bragg gratings (FBGs) are well protected inside the os3500 body. One FBG measures strain while the other provides integrated temperature compensation. Since there are no epoxies holding the fiber to the carrier, long-term stability is ensured by design. 

In side-by-side comparisons with vibrating-wire and foil strain gages, the os3500 is equally sensitive and accurate, while providing 100 times more fatigue life. The os3500 strain gage is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.
