Line-type Optical Temperature Sensor (Korea Photonics Technology Institute)

Line-type Optical Temperature Sensor

  • Policy features
    This fiber-optic temperature sensor is used to heat management for data center server, BUS DUCT of semiconductor/display factories, power line cables for power plants, gas storage tanks, tunnels, mill sintering furnaces, shipyard underground power lines, etc. It is a product that can be used for measuring temperature distribution in places where large-scale monitoring is required and for fire prevention diagnosis systems. It can measure the ambient temperature in 1 m with a length of around 20 km.
    Implementation of an assembly-type method for each module for convenient maintenance by applying technologies that can be used in both single mode and multimode.
    345 kV Underground Transmission Cable Field Demonstration Test and Technology Verification (KEPCO Underground Electric Power District and others).
