T202 / Steel Narrow Anchor FBG Sensor Datasheet

Key Features

Small size with excellent temperature strain linearity. The precision-made FBG structure of the T202 sensor yields a simple transducer configuration of high resolution, linearity, and measurement repeatability. Clear high SLSR response.

Ultra-reliable installation. The T202 aims to eliminate the need for civil, industrial, medical, security, rail, marine, aerospace, energy and other engineers and researchers to all become materials experts for bonding sensors that will not slip from their various application surfaces. Ideally balancing cost, performance and reliability, the T202 is here to simplify the process of using Fiber Bragg Gratings and to accelerate the creation of new and attractive fiberoptic-based commercial solutions. Available for fibers with diameters from 50μm to 155μm and with standardized and custom size stainless steel anchors (pads). The fiber pigtails can be protected with Teflon or other types of loose tube jacketing.

Easy to daisy-chain. Well suited for projects that include the need to provide optical filtering, to monitor strain, temperature and other engineering parameters at many points. The T202 can be provided as a single FBG optical component or in FBG arrays of various lengths, with a flexible number of FBGs, and with the steel anchors located at customer-specified distances along the fiber.

Proven field performance and reliability. The T202 Stainless Steel Anchored FBG Sensor is a rugged low-cost optical component with stable operation for highly accurate and reliable long-term use in various applications, as is. It is also the core element for the development of an expanding range of devices such as strain, vibration, acceleration, displacement, tilt, pressure, load, temperature, and other types of optical sensors. The Technica TS900 Spot-Welder is optimized for installing Technica sensors.

 

Description

The T202 is a Polyimide coated Single-Mode (SM) Fiber based Fiber Bragg Grating (FBG) that is factory-bonded to a narrow stainless steel pad or “anchor” on each side of the FBG. The proprietary non-slip bonding process used for manufacturing the T202 yields ultra-high consistency and enables direct and immediate field installation of the FBG to many types of surfaces by spot-welding, chemically bonding (epoxying), or screwing-in the FBG’s steel pads to the customers’ surfaces.

Available in a wide range of optical and mechanical specifications. With its sensor packaged (inscribed) directly into the core of the fiber, the T202 can be used as is, or it can be packaged into a variety of higher-level sensors for use in optical sensing systems. Small-size and fast response time. Excellent wavelength to temperature and wavelength to strain linearity. The T202 is designed to make handling and installation fast, easy and intuitive. Delivers the many advantages inherent to all FBGs.
