os3150 – Rugged FBG Strain Sensor

Published by under General,Sensors

Micron Optics has just released the os3150, a rugged strain gage based on fiber Bragg grating (FBG) technology. Optimized for outdoor installations on steel structures, the os3150’s stainless steel carrier holds the FBG in tension and protects the fiber during installation.   Like the os3110 and os3120, installation is quick and easy.


In side by side comparisons with foil strain gages, the os3150 is equally sensitive and accurate, while providing for greater strain range and 100 times more fatigue life. The os3150 strain gage is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.

A year ago I introduced ENLIGHT to you as it was first released. ENLIGHT provides an all-in-one software solution to configuring sensors connected to Micron Optics instruments, converting wavelengths to engineering units for hundreds or thousands of sensors, displaying data in charts, graphs or images, setting alarm limits and sending alerts, and saving data. Now I’m back with an update on the features of our next release which is coming soon.

In the past year we have worked to bring the software from an early Beta state to an optimized, faster running tool that’s ready for broad deployment. In response to customer feedback, our major focus has been on data management. For example, systems sampling hundreds of sensors at 1 kHz produce large amounts of data in a short time. New ENLIGHT features will allow files to be managed by size (e.g., once a file reaches 10MB, create a new data file), or by time (e.g., create a new file every day or hour). All files are stored in an automatically created directory structure organized by year, month, and day. Users will be able to choose what data to save, i.e., full spectrum traces, peak locations, FBG wavelengths or the calculated sensor values in engineering units.

Users will also be able to choose when data is saved. Data saving can be either continuous or triggered by an event such as a sensor moving into a warning or alarm condition. Users will select which sensors trigger data saving and then what data shall be saved. Data buffered prior to the event can also be included in the event file.

There will be more flexibility in manipulating data as well. Separate averaging controls will be available for spectra, peaks, FBGs, and sensor values. Another new feature will allow ENLIGHT to calculate the derivative of a sensor value so that the rate of change of a sensor value is known which is useful in fire detection applications.

Error handling will become more robust. Instrument diagnostic tools built into ENLIGHT will allow it to automatically recover to its normal operating state following a power interruption. Additionally, multiple copies of ENLIGHT will be able to run simultaneously on a single processor, thus managing more than one interrogator from a central PC.

For applications where custom user interfaces are required, users will be able to send commands to ENLIGHT via Ethernet to stream processed sensor data, zero sensor values, or retrieve saved data. In such cases, ENLIGHT acts as a signal conditioner simplifying integration of optical data with data streams from other systems.

The bottom line is that optical sensors are continuing to become easier to use. Better software, better instruments and better sensor packages are making this possible. Soon we’ll have more news on new sensor developments at Micron Optics and elsewhere.

Measuring Strain and Temperature in Light

Published by under General,OS Technology

In the past dozen years we’ve seen fiber optic sensors (FOS) being discovered by engineers around the world for myriad applications. With each new application, the unique capabilities of FOS (or more specifically, fiber Bragg grating (FBG) sensors) are leveraged and highlighted.

We’ve also seen that our most formidable competitor isn’t another FOS company; it is lack of awareness. One way we are reaching out is inviting the Atlanta chapter of the Society of Manufacturing Engineers to our offices for an introduction to FOS. Tom Graver will be presenting “Measuring Strain and Temperature in Light” on September 22 here at Micron Optics. We are excited to talk with a new group and to see what ideas they bring to us.

If you are in the Atlanta area and would like to attend, you can register at

Installing Optical Sensors

Published by under General

Installing fiber optic sensors is really quite simple. Micron Optics has recently added some videos showing how quick and easy installing the os3100 and os3200 can be. Here is the video for the os3110 weld type sensor.
