HBM launches NewLight, a range of robust and reliable optical sensors ideal for industrial engineers carrying out strain, tilt, temperature and acceleration tests. The devices are based on Fiber Bragg Grating (FBG) technology, reflecting advances in optical measurement standards and merging the advantages of HBM’s former optical product portfolio into one comprehensible line of optical sensors.

The devices are suitable for multiple applications including vehicle validation, monitoring structural health of bridges, high buildings or tunnels, battery temperature tests and wind turbine durability. FBG based sensors offer many advantages compared to electrical sensors, being immune to all electromagnetic effects and offering long-term stability, with no zero-point drift because of the wavelength-based measurement. The sensors are suitable for glass and carbon fibre composite materials often used for highly stressed structures, such as airplanes and wind power turbines.

NewLight also enables large strain measurement ranges at increased long-term stability, making them suitable for structural health monitoring, as they are quick and simple to install and highly resistant to harsh environmental conditions such as humidity, rust and salt.
