Description

The sm125 Optical Sensing Interrogator meets the growing demand for measuring strain, pressure and temperature in civil, down-hole 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 Japan.

Applications

• Long-term field measurements of multiple fiber Bragg grating and extrinsic Fabry-Perot sensors
  

• Analysis of fiber Bragg grating sensor behavior and shape using internal, high-powered, high dynamic range detection circuitry
  

• High volume OEM applications where custom capabilities are required
  

• Sensing and measurement of strain, temperature, pressure, etc.
  

Benefits

No Calibration - The sm125 never needs calibration. Wavelength is calibrated automatically on every scan. Some models include an internal NIST-traceable gas cell for applications where tight absolute measurements are needed.

Robust Operation - The sm125 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 sm125 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.

Full Spectrum Flexibility - Sensors in special applications can produce unique spectral profiles. The sm125’s full-spectral data allows the user to get a complete picture of how the sensor is performing under all conditions.

Fast Peak Detection - Using the full-spectrum data, onboard peak detection capabilities are included and can be customized for each application.

Compact Size - The sm125 weighs a mere 2 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 sm125 is offered in three standard models. Custom configurations allow optimization of unit costs and feature sets for volume customers. sm125 instruments use Ethernet to network to external PCs for data analysis.
