Description

The sm130 Optical Sensing Interrogator meets the growing demand for fast interrogation of fiber optic sensors in harsh environments. This very versatile instrument can also interrogate up to fifty sensors simultaneously on up to 4 fibers at 1 kHz or hundreds of sensors at 100 to 500 Hz. With the Micron Optics sm041-416 channel expansion unit, the sensor count can be quadrupled. The result is a single system that can measure both dynamic and static phenomena for large complex structures. Strain measurements are the most common sm130 application, but the system is equally capable of measuring acceleration, pressure, temperature and more.

The small, accurate, powerful and economical sm130 combines an industrial PC with Micron Optics' robust, high-power, low-noise swept laser source in a single rugged package. 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 Japan.

Applications

• Measurements using FBG strain gages, temperature probes, accelerometers and pressure sensors
  

• Dynamic and static simultaneous measurements of hundreds of sensors on multiple fibers
  

• Continuous, decades-long structural health monitoring of ships, aircraft, trains and other complex structures
  

• Permanent installations for tracking the condition and performance in smart structures like bridges, dams, buildings and tunnels
  

Benefits

No Calibration - The sm130 never needs calibration. Wavelength is calibrated automatically on every scan.

Robust Operation - The sm130 survives harsh environments. Tests at professional facilities, meticulous customer evaluations, and tests at Micron Optics headquarters prove how well Micron Optics products are designed and built.

Huge FBG Sensor Capacity - The sm130 can monitor a huge number of multiplexed fiber Bragg grating sensors. With 80 nm of wavelength range per channel and up to 16 optical channels, users of the system have great flexibility in designing their sensing system to maximize the number of sensors per interrogator, and to minimize total solution cost.

Fast Peak Detection - FBG peak reflections provide the information needed to relate wavelength to strain, temperature or other measurands. The sm130's internal peak detection circuitry delivers fast, repeatable peak detection. The user can optimize peak detection parameters to meet each particular application.

Compact Size - The sm130 weighs a mere 2.5 kg and is smaller than a shoe box. All ports are accessible from one side allowing integration into existing control panels.

Verifiable Performance - The performance we quote is the performance you will get. Some manufacturers boast fantastic numbers for accuracy, resolution, and repeatability, but how will they perform in your application?

Modular Design - The sm130 is offered in three standard models. Custom configurations allow optimization of unit costs and feature sets for volume customers. sm130 instruments use Ethernet to network to external PCs for data analysis.
