The sm125 Optical Sensing Interrogator meets the growing demand for measuring static strain, pressure and temperature in civil, downhole oil, and pipeline applications where both high accuracy and low cost are required. Most of these applications require the durability and versatility of the fiber Bragg grating based strain, temperature and pressure sensors for which the sm125 is well suited.

The small, accurate, powerful and economical sm125 combines an industrial PC with Micron Optics’ robust, high-power, low-noise swept laser source. Micron Optics instruments are installed in hundreds of harsh applications around the world from oil platforms in Brunei to marine vessels in the North Sea to tunnels in

ENLIGHTPro is a free utility included with Micron Optics sensing interrogator systems and provides a single suite of tools for data acquisition, computation, and analysis of optical sensor networks. ENLIGHTPro combines the useful features of traditional sensor software with the specific needs of the optical sensor system, making it easy to optimize optical properties during the design and implementation phase of an optical sensor system. Intuitive data display and additional graphing and data visualization features make ENLIGHTPro easy to use.
