Xiamen Fengxing Optoelectro-tek manufacts world’s class optical measurement systems for a broad application of intelligent municipal engineering. We provide cost effective, smart, and highly reliable distributed temperature, strain and vibration measurement systems with high sensitivity. The fully distributed fiber temperature measurement system provides an intelligent fire alarm, used for identifying hot spots on the power core, power station, warehouse, industrial furnace, etc. The distributed vibration system gives smart alarms on many pipeline leakages, such as natural gas, water, oil, and heat transportation systems. Our strain measurement allows a real time infrastructure health monitoring of bridges, tunnels, railways, etc. By integrating the Geographic Information System (GIS) technology, we demonstrate all types of unsafe hot spots or regions in an electronic map and locate them with high accuracy.
