Click here to download the Datasheet

Description

The T890 is a Gold coated fiber based Fiber Bragg Grating (FBG) Array, packaged into a virtually frictionless Inconel 625 tube, with a ceramic transition to a high temperature rated protected fiber pigtail. These daisy-chained FBG sensors are ultra-small and are designed for use in distributed, quasi-distributed, and multi-sensing-point applications with the added requirement of minimal intrusion.

The T890 optical temperature sensing probe consists of up to 40 Fiber Bragg Grating sensing elements embedded in Gold coated fibers. Optional Copper, Aluminum, Polyimide, and Acrylate coatings available, depending on the desired temperature rating. Inconel tube hermetic sealing (capping) service is available upon request. Sensing probe length limitations apply.

Key Features

Temperature linearity. The precision FBG structure and top quality single-mode Gold coated fiber used in producing the T890 yield a simple transducer configuration of high resolution, linearity, and measurement repeatability.

Customizable Multi-Point Sensing. Well suited for projects that include the need to monitor many points, as the T890 is a ready to deploy sensing probe available in customer-defined distances between FBGs, and featuring a flexible number of FBGs to match the requests of our customers, with a maximum sensing probe length of 25m, not including the pigtail. Standard connectors termination or spliced to specialty cables.

Reliable high-temperature measurements. The T890 was designed for projects that require both the availability of high-temperature-resistant FBG sensors and stable operation for highly accurate measurements over the long-term. The probe design makes handling and installation very easy. Fastening methods are by simple mounting brackets, by steel tube bonding, laying, inserting, or embedding.

Proven field performance. The T890 High-Temperature Multipoint FBG Sensing Probes are a commercial product manufactured in increasing volumes. Installed in applications worldwide with practically no returns since the initial release. The world-leading sensing probe lengths and outer diameters available combined with proprietary ceramic transition and hermetic sealing technology make the T890 a valuable sensing product that extends the range of high-temperature applications addressable by FBG based optical sensors.
