Description:


  Fiber Bragg Grating Temperature sensor is mainly used for temperature range from 40 degree below zero upto 800 degree. As its safty feature, it is wildly used at power plant , oil tank , Steel production monitor aspects.


  SAMYON can supply FBG temperature sensor with different package material according to realapplication area: Ceramic, Stainless Steel Pipe, Quartz tube, Engineering Plastic , Rubber and diameter 2mm stailess steel cable specially for higher temperature with femto FBG.The Ceramic is mainly for High Voltage Transformer and Switch Gear at power plant.

  Stainless Steel pakcaged type is used for temperaute monitor at Construction Health aspects.

  2mm Stainless cable package type can reach to 800 degree for steel produce factory.

  Bared Fiber Bragg Grating itself also can test temperature by embedded in relative material to increase temperature senstivity.

  We can supply FBG sensor according to clients application request.


Application:


  Telecommunication, Lasers and sensors, filter

  Wavelength Division Multiplexing Transmission System

  High tensile resistance and anti-electromagnetic interference


Feature:


  1. FBG sensor increases the sensor amount greatly byseries connection on one opical fiber cable.

  2. FBG Sensor is capable of a long-distance measurement.

  3. FBG Sensor is particularly suitable for field use.

  4.FBG Sensor can be applied to the static tests as well as the high-speed dynamic.
