Description The sm130
Optical Sensing Interrogator meets the growing demand for fast interrogation of
fiber optic sensors in harsh environments. This versatile instrument can interrogate
up to 500 sensors simultaneously on up to 4 fibers at 1kHz. 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 and temperature.
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.
