newLight FS63 Optical Temperature Sensor for Accurate and Reliable Temperature Measurements

The newLight FS63 optical temperature sensors are based on the Fiber Bragg Grating Technology (FBG) and designed to accurately retrieve temperature measurements in large structures and machines without interferences from external noise. Furthermore, their small size and lightweight structure makes them the ideal choice for hard-to-reach locations and measuring points granting low transmission losses even under harsh environments.

With improved temperature stability, these sensors are particularly suited for temperature measurements in large structures and thermal mapping in electrical machines. Moreover, the FS63 temperature sensors can be used for thermal compensation of other optical sensors. Different calibration options allow for diverse temperature ranges or cost reduction for when the sensor is used as a temperature compensation element.
