PRODUCT INTRODUCTION

os3600

Embeddable Optical Strain Sensor

The os3600 Embeddable Strain Sensor measures average strain over the length of the gage while providing integrated temperature compensation.

MAIN SPECIFICATIONS

PRODUCT DESCRIPTION

The os3600, based on fiber Bragg grating (FBG) technology and is available two gage lengths of 25 or 100 cm. Intended exclusively for embedding in concrete structures, disk ends of the os3600 form a solid bond to surrounding concrete or grout. Universal ends allow the user to employ bolt-on, weld-on, or custom end brackets for attachment to rebar or other structures before embedding.

A rugged, Teflon and steel-shielded body, armored cables, and optional connector protection fittings make the os3600 suitable for harsh environments. Two FBGs are well protected inside the os3600 body. One FBG measures strain, and the other provides for 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 os3600 is equally sensitive and accurate, while providing 100 times more fatigue life. The os3600 strain gage is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.

This sensor can be used alone or in series as a part of an FBG sensor array. Installation and cabling for such arrays is much less expensive and less cumbersome than comparable electronic gage networks.
