Stable Densor Designs + Better Sensor Selection + Enhanced Data Analysis = Vastly Improved Results

It is relatively easy to achieve good strain sensing results from optical sensors when working in lab conditions. Temperature dependence in a stable strain gage can be largely eliminated using only the built-in temperature compensation gage (figure 1). This is a plot showing data from an os3155 optical strain sensor mounted on a test beam. This is representative of data where sensor and substrate are at a common temperature, such as are found inside an [...]

Micron Optics Releases Fiber Optic Temperature Sensing Cable

Yesterday, Micron Optics announced the release of the os4400, a fiber optic temperature sensing cable. This cable addresses a growing need for durable, low-cost temperature sensing in areas with limited access, such as tunnels, bridges, mines, downhole and other applications where distributed measurements are needed at specific points over long distances. You can read the full press release here. Micron Optics os4400 temperature sensing cables are available immediately. For more information, please go to our sensors [...]

How do FBG sensor interrogators work?

Here are the basics. Light is sent into a fiber and reflects back from the FBG. The reflected light travels back to the instrument’s photo detectors and is compared to wavelength reference artifacts so that the instrument can determine the position of the center wavelength of the FBG. Wavelength information is converted to engineering units, e.g., 1.2 picometers of wavelength shift could correspond to 1 microstrain. The actual translation is given by the gage factor [...]

A new tool for managing FBG sensor data

I’ve written about why many applications must use FBG sensors, but how do users deal with the data? Conventional electronic gages deliver an analog signal that’s proportional to the strain or temperature change. Optical gages deliver a digital signal that reports an absolute wavelength value indicative of the strain, temperature, displacement, pressure, etc. Converting from wavelength to engineering units requires some basic arithmetic. For example, the gage factor for an FBG strain sensor might be [...]

Optical Sensing Interrogators – what distance?

Some sensing applications require the ability to measure over very long distances, but what is the range of instruments that measure fiber Bragg grating sensors? The answer comes down to loss budget, i.e., how much light is lost from the fiber core as it travels along great lengths and through connectors and bends. And loss is a round trip affair. Light is sent out and reflections must travel back the same distance, thus the things [...]

Sensing FAQ

Micron Optics has been helping customers use fiber optic sensors since 1997. In that time we still hear a common thread of questions. Here are the top seven: Q: How many FBGs sensors can be on one fiber? A: It depends on the range of measurement. For example, if the instrument (i.e., FBG interrogator) has an 160 nm wavelength range, and one needs to measure strain of +/-800 microstrain at each sensor, this translates to [...]

ASCE Pipeline Division International Conference

New applications for FOS come about in many ways. Starting more than ten years ago university researchers led the way, but, in recent years, more commercial entities are solving problems using FOS. One example is Durham Geo Slope Indicator (DGSI) in Stone Mountain, Georgia. They’ve earned a solid reputation for providing vibrating wire (and many other technologies) for geotechnical measurements. But for some of their customers with buried pipelines, high EMI conditions made the vibrating [...]
