Description：
The T210 is a small dimension high sensitivity sensor designed for monitoring cracks and vibrations in surface mounted applications.
The T210 optical sensor consists of a Fiber Bragg Grating (FBG) sensing element embedded in a curved steel frame. This patented sensor yields excellent wavelength to crack growth linearity and its fast response time also makes it ideal for vibration monitoring.
The T210 crack sensor is designed to make handling and installation fast, easy and intuitive. It delivers the many advantages inherent to all FBG based sensors. The sensor’s cable specifications listed herein represent the most popular configuration. The manufacturing process for the T210 allows for significant variations in sensor and cable construction including sensors at other wavelengths, termination by other types of optical connectors, as well as cable availability in custom lengths and with customer defined spacing between sensing points.
Used extensively in various civil structures, including buildings, pillars, and bridges. New applications in power transformers.
Key Features：
Excellent linearity. The curved steel structure of the T210 and the advanced fiber to steel bonding technique used in producing this sensor yield a simple transducer configuration of high linearity and repeatability.
Crack growth monitoring. Well suited for projects that include the need to monitor uneven or grossly misaligned cracked surfaces. Produced in sizes to serve an expanding spectrum of applications.
Vibration monitoring. The FBG element at the core of this sensor responds in nanoseconds. The steel frame is an ideal vibration transfer mechanism from the structure under test to the FBG core.
Easy deployment. The original design eliminates the high precision alignment and diligent surface preparation of the structures to be monitored that is normally required of other optical sensors targeting a similar measurement.
Low cost and long lifetime. The T210 sensor construction focuses on demanding projects that require both low cost per sensing point and stable operation over the long-term.
