The T165 is Fiber Bragg Grating (FBG) Array inside a loose, virtually frictionless steel tube, and it is available in a wide range of optical specifications. Naturally packaged directly in singlemode (SM) fiber, these daisy-chained FBG sensors are ultra-small and are designed for use in distributed, quasidistributed, and multi-sensing-point applications with the added requirement of minimal intrusion.
The T165 optical temperature sensing probe consists of 1 to 99 Fiber Bragg Grating sensing elements embedded in polyimide, copper, or gold coated fibers, depending on the desired temperature rating. The sensing array is then protected from strain by an outer 316 Stainless Steel tube. Steel tube capping service is available upon request. SS tube length limitations apply. The sensor yields excellent wavelength to temperature linearity.
Temperature linearity. The precision FBG structure and top quality single mode fiber used in producing the T165 yield a simple transducer configuration of high resolution , linearity, and measurement repeatability.
Daisy-chaining with no limits. Well suited for projects that include the need to monitor many points as the T165 is a ready to deploy Stainless Steel tube protected FBG Array, available in customer defined distances between FBGs, and featuring a flexible and virtually limitless number of FBGs to match the requests of our customers, to optimally fit their applications. Standard connectors termination or spliced to specialty cables.
Reliable high-temperature measurements. The T165 was designed for projects that require both the availability of hightemperature resistant FBGs sensors and stable operation for highly accurate measurements over the long-term. The simple 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 T165 High – Temperature Multipoint FBG Steel Probes are a commercial product manufactured in increasing volumes . Install e d i n applications worldwide with practically no returns since initial release. The T165’s steel probe packaging and sealing technology is a valuable sensing product line enhancement that extends the range of high-temperature applications addressable by FBG based optical sensors.
