T880 / High Temperature Ceramic Sensing Probe to+1000C



The T880 is a Single-Mode (SM) Fiber based High Temperature Fiber Bragg Grating (HTFBG) Sensing Array, packaged into a precision manufactured Ceramic tube and rated for operation to +1000C. The daisy-chined HTFBG embedded sensors are ultra-small and are designed for use multi-sensing-point applications with the added requirement of minimal intrusion. Immune to EMI and lightning.

The T880 optical temperature sensing probe consists of up to 40 Fiber Bragg Grating sensing elements embedded in single-mode fibers. Available with Gold, Copper, Aluminum, Polyimide, or Acrylate fiber coatings, or as coating-free fiber sensors, depending on the desired temperature rating and application details. Ceramic tube hermetic sealing (capping) and calibration service are available upon request. Sensing probe length and diameter limitations apply.

Key Features:

Temperature linearity. The precision-made HTFBG array structure written into the fibers’ core for producing the T880 yields 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 T880 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 1m, not including the pigtail. Standard connectors termination or spliced to specialty cables available.

Reliable high-temperature measurements. 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 T880 installation is easy and fastening methods are by simple mounting brackets, and by ceramic tube bonding, laying, inserting, or embedding.

Proven field performance. The company’s family of 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, outer diameters options, and proprietary ceramic transition and hermetic sealing technology make the T880 a valuable sensing product that extends the range of applications addressable by FBG sensors.
