New Family of FBG Optical Sensors featuring Zeus’ PEEK Coating Now Available for Use in Harsh Environments

FBG Sensor Array with Rugged PEEK Coating

FBG sensors are now available for operation in various metal prohibiting, corrosive, toxic, and chemically active environments

FBGs are reliable all-fiber optical components that have been used for making accurate and reliable temperature and strain measurements for over two decades. However, due to previous technical limitations, most applications in hot harsh environments were typically off limits. A new generation of T150 ruggedized Fiber Bragg Gratings are now available for operation in various metal prohibiting, corrosive, toxic, and chemically active environments to 260 Degrees Celsius. Protected by their Zeus PEEK outer layer, these new sensors are now solving measurement challenges in many existing and new markets. Optical sensors are widely used in industry and in research and development laboratories.

At its core, the T150 optical cable consists of an array of Fiber Bragg Grating (FBG) sensors. The original design of this cable eliminates the fragility typically associated with single layer coated fibers and enables significant field installation productivity improvements. Measurements can be made at one or more individual FBG points spaced at customer defined lengths. The sensing cable is designed to make handling and installation fast, easy and intuitive and is terminated with standard optical connectors. The T150 cable construction focuses on demanding projects that require stable operation over the long term.

While Technica now offers several standard T150 sensor configurations, the company is pleased to work with each customer to optimize its sensors for the specific applications under consideration. Proprietary and licensed technologies are used to ensure that each sensor has a stable optical core and a matching material composition and outer diameter for device protection that is well fit for the environment in which the sensor will be used.

“This new family of sensors is designed for harsh environments. The outer layer of the cable is a tight buffer, chemically inert, abrasion resistant PEEK polymer coat which protects the FBG sensors and ruggedizes the cable. Polyether Ether Ketone (PEEK) is an advanced material used for…
