Fiber-optic sensors are common in explosive environments or in the presence of strong electromagnetic fields – in these areas, sensors that rely on electrical signals may present a risk of explosion or fail to operate correctly. Contrinex manufactures world-class fiber-optic sensors and amplifiers that not only meet these needs, but also present a highly practical means of sensing in confined spaces. With bend-radii as small as 2mm, reliable, accurate sensing is possible even in the most inaccessible areas.
