Description:
The T875 is a Single-Mode (SM) Fiber based High Temperature Fiber Bragg Grating (HTFBG) Sensor, packaged into a precision manufactured Ceramic tube and rated for operation to +1000C. The HTFBG embedded sensor is ultra-small and is designed for use in single-sensing-point applications with the added requirement of minimal intrusion. Immune to EMI and lightning.
The T875 optical temperature sensing probe consists of one Fiber Bragg Grating sensing element embedded in a single-mode fiber. 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 is available upon request. Sensing probe length and diameter limitations apply.
Key Features:
Temperature linearity. The precision made HTFBG structure written into the fibers’ core for producing the T875 yields a simple transducer configuration of high resolution, linearity, and measurement repeatability. The sensor’s BW (FWHM), REF, and SLSR are dependent on the temperature rating.
Customizable Single-Point Sensing of High Temperature. Well suited for projects that include the need to monitor high temperatures at individual points, with sensing probes from 10mm to 100mm in length, not including the pigtail. Customizable sensing probe outed diameters from 0.5mm to 3mm. Standard connectors termination, or splicing 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 T875 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 initial release. The world leading sensing probe lengths, outer diameters options, and proprietary ceramic transition and hermetic tip sealing technology make the T875 a valuable sensing product that extends the range of applications addressable by FBG sensors.
