Temperature measurements in industrial or R&D applications are conventionally based on thermocouples. But the single point method fails, if continuous temperature profiles are required at a specific date. Glass fibers are light weight, minimal invasive, can easily be integrated and used to measure in liquids, strong electro-magnetic or RF fields. Installation is easy and time saving. Temperature profiles with spatial resolution in the order of millimeters allow a much deeper understanding of heat exchange or flow processes. They help to allocate local hot-spots, feed existing FEM models and improve the degree of efficiency and safety wherever temperature counts.
