FBG Pressure Sensor

The pressure sensor is designed to measure fluid pressure or levels.
There is double FBG inside the stainless steel housing. One FBG is used to measure the pressure another FBG is used to monitor the temperature. So it is temperature compensated.   For multi-point pressure detection, such as inside a pipeline, multiple pressure sensors can be cascaded as a sensing array for field installation. We can customize such a field installation requirement as requested.
Different mounting method is available
