Test and measurement group HBM has expanded its range of optical strain transducers to provide more flexibility in strain gauge measurement applications.
Its FiberSensing optical interrogators and sensors are based on Fiber Bragg Grating (FBG) technology, which offers a solution for long-term structural health monitoring in more demanding applications.
They are designed for both laboratory testing and field deployment across a range of industries including civil engineering, energy, R&D, aeronautics and gas pipelines.
They can be used in harsh environments such as structure monitoring of pipelines and bridges and measuring high strains.
According to the company they are easy to install, are electromagnetically, safe and can be used in highly explosive environments.
HBM’s optical sensors can determine strain, temperature, acceleration, displacement, and tilt in components, structures, and environments where conventional technologies have reached their limit.
Particular sensors can be used for extreme strains measuring up to ±10000 µm/m.
Others are suited to operating under high temperatures of 100ºC.
