Fiber Optic Sensing

FBG sensor based on fiber Bragg grating technology has special advantages. The most important thing is that the sensing signal is wavelength modulated and has strong multiplexing ability. Measurement signal is not affected by fiber bending loss, link loss, light source fluctuation and the influence of factors such as the aging of the detector. Moreover, optical fiber sensors present undeniable advantages such as high fatigue limits, multiplexing and immunity to electromagnetic interferences. When multiple sensing FBGs are connected on a single fiber and the sensors are embedded to the structure, several parameters can be monitored at the same, hence realized a quasi-distributed sensing system.
T&S’ FBG Sensors have been widely used in spacecraft and ship, civil engineering structures, power industry, petrochemical Industry, medical and chemical sensing, and telecommunication engineering etc. With our variety of high quality FBG sensors you are able to measure an array of parame

FBG sensors are easy to install, electromagnetically safe and can also be used in highly explosive atmospheres, but having the right interrogator in place is also important to retrieve the most accurate measurements.
FBG Interrogators are high-precision measuring instruments for signal obtaining and processing from FBG sensors under operating conditions. Suitable for large scale sensing networks, T&S’ FBG interrogators (TS-WI) controls up to 24 channels (4 channels on TS-WI-HS) and provide precise and high resolution measurements through reliable software interfaces and remotely read all connected sensors in real time.

An optical interrogator, also known as measurement unit or data acquisition system, is an optoelectronic instrument, which allows the reading of fiber Bragg grating (FBG) sensors in static and dynamic monitoring applications. T&S FBG interrogator can measure a large sensing network composed by various types of sensors (such as strain, temperature, displacement, acceleration and so on) connected along multiple fibers, by acquiring data simultaneously and at different sampling rates. Whether your application requires static or dynamic real-time acquisition or periodic monitoring, T&S always offers right system for your projects. The robust and powerful interrogators provide fast and highly accurate measurements from multiple FBG sensors in the network.
