Through the core of uv light optical guidance method can make FBG

Special optical fibers can not only used in communication and defense field, now fiber optic technology based on special optical fiber sensor are monitoring environment, all the structures stress testing and other fields found more and more applications. Optical fiber sensor has reliable work, use convenient, cost competitive advantage many merits. Britain Fibercore company leading manufacturer of special fiber chrisEmslie doctor in this article expounds the emerging company fiber-optic sensors Insensys how to use their product development from the ship to the oil pipeline in the different application of optical fiber sensor.
Special fiber usually use light amplifiers, fiber-optic gyroscope and acoustic equipment. However fiber deft, flexible small wind turbines and reliable character also make masts of rotor, sailing in the sensor and municipal engineering etc find applications. Because fiber from electromagnetic interference, so can work in May produce heat and electric spark in the dangerous conditions. Use plastic tape in production or site construction with easily moulded into various shapes. Although the optical fiber sensing technology has not caused universal attention of the world for the optical fiber sensing instead of traditional electronic measurement benefits cognitive are growing. Optical fiber pressure and temperature measurements of the leading firms have developed easy to use, reliable and the economy effective sensor.
For in various occasions also outstanding wind turbines manufacturer special optical fiber, Intensys company started looking for a world leading manufacturer of special optical fibers Fibercore company¡¯s help. Fibercore in special light field already has a 20 years of experience, some in providing clients with high quality of advanced single-mode optical fiber field prestigious.
Intensys company VPMarkVolanthen explained: "our main objective is to provide able to work in a world, can endure extreme farthest corner the climatic conditions and reliable sensor. This is what we wind generator need and have ISO9000 quality certification, with strict quality assurance program of the supplier and the reasons. Fibercore just so that you can trust company. We and they discussed we sensor, they can provide detailed requirements we detailed information, appropriate fiber, thus let we launched the product price more than electronic sensors. Through farther in the distance, or achieve higher deploy sensor precision of the Fibercore suggest we adopt, fiber grating (FBG) and appropriate technology to change the doped fiber refractive index and photographic rate."
Through the core of uv light optical guidance method can make FBG. Ultraviolet irradiation resulted in glass refractive index periodically modulation effect. This periodic decided the grating only reflect specific wavelengths of light, so it can be used to make the light filters or reflector. Through will fiber grating and appropriate can cause periodic changes induction mechanism to cooperate, can monitor including stress, temperature, vibration and pressure etc, many physical quantities.
Fibercore through and Insensys cooperation can provide unique numerical aperture and die making the fiber MFD field diameter in reducing fiber loss while assure enough photosensitive effect. With no small MFD making traditional high fiber need complex the high cost of removable connectors, Insensys products more reliable, also cheaper. Fibercore company in the first phase of product design on developing and Insensys cooperation, so can recommend the most appropriate fiber optic solutions. This cooperation usually is rare things in the industry.
Have Fibercore support, Insensys can also be used in sensor system to optimize the selection of special optical fibers. Similar to the application of oil pipeline usually requires a long distances can distributed in multiple sensor system within the use. This usually can use sensor array of every single sensor, the output through time multiplex (TDM) composite up way.
TDM is a multiple data flow or signal when using different to mix into a gap in the technology transfer signal paths. With WDM WDM technology adopted the different signal a different wavelength of mechanism using the same wavelength is different, TDM support of all data channels and therefore do not need adjustable laser light devices such complicated and costly. Using this technology making sensor therefore cheaper.
The system USES is Insensys, this is the only technology TDM to allow more than 100 sensor deployment of stress in a fibre-optic sensor system, the whole measuring scope reach + / - 6,000 tiny stress index, no light switch or more paragraphs of optical fiber. Contrast ratio, WDM optical sensing system of sensors, due to the number of the number of available wavelength boundaries and limited.
In 2003 Insensys successfully developed the optical fiber strain sensor and temperature sensor, and obtained the widespread application. Because sensors can use plastic belt moulded into different shapes, they can be embedded in the surface of the content being watched, the process can be made before also can be in the making. The sensor is usually applied at sea surface mounted by using this method the change. Surveillance load For some large ships, this system can be in early warning given overload. The ship, with about race are due on wind, the wind can ship state data, can help athletes more effectively game.
The most recent period, sensing technology began to wind power for testing and optimizing rotor system. As the fastest growing energy technology, increasing the size of the rotor. These fancy usually werebig, and installed in the relatively remote locations. Surveillance engineers need for real-time understanding of these fancy condition. Sensors usually in the rotor assembly are easily installed in fancy.
The oil and gas industry also in cost and security concerns began to use sensors. Optical fiber sensor without any connections, not generate heat, using only a few light, these characteristics make optical fiber sensor become dangerous environment ideal choice. Optical fiber sensor can also be used in key production equipment¡¯s long-term high reliable and stable surveillance. These sensors almost from the water, and can be used for the high pressure influence deep-sea equipment installation and monitoring.
Insensys sensor also widely used in Bridges, roads, tunnels, dam in such municipal engineering. Not only for surveillance stress and temperature, they also can monitor the foundation shift, fatigue and injuries. And because these data can be the real-time data acquisition, also makes it easier for buildings of maintenance, reduce managers regularly check cost.
MarkVolanthen added: "two years, Insensys founded the scale have doubled, the company¡¯s products have been applied to Japan, America, Australia and Europe countries. All these successes in the cooperation with Fibercore are inseparable. Fibercore offer us not only, also is a leading fiber of their experience and knowledge."
When most people will also the application limitation of special optical fibers in communication and defense applications Fibercore will help, Insensys found sensing the market. Today, single-mode optical fiber not only for the oil and gas industry, also in to help us realize renewable energy dream. Although Fibercore and Insensys such cooperation in the industry is rare, but not only for our mutual benefit and cooperation on final consumer also very favorable. Insensys sensor for reliable, easy to use and adapt to all kinds of existing structure and wide acclaim. The most important this is a replacement of traditional technology economic solutions.
