The recent development and the spread of the technology of optical fibres has been an advantage for the telecommunications performances as one is able to monitor multiple parameters simultaneously.
The fibre optical sensors offer numerous advantages in regard to the conventional electronic sensors like:
- Reduce dimensions and weight.
- Incapable to convey electrical current.
- Immunity to electromagnetic and radio interferences.
- Robust, more resilient to hard environment.
- High sensitivity range.
- Multiplexing capacity for sensing networks.
- Capacity for remote sensing.
- Capacity for multifunctional sensing.
- Facility to integrate structure.
As of today, the optical fibres are widely used in a variety of physical range (temperature, pressure, movements, vibrations, velocity, acceleration, strength, acoustic field, magnetic field), environmental like pH, humidity, viscosity) and chemical species.
The basal OptoAdvance , it has to types of sensors, Bragg grating, in fibre, and the refractometric sensors.
Why fibre optical sensors?
The use fibre optical sensors are beneficial and have numerous advantages connected to the technology like for example: the integration of the sensor in the communication channel. Is extremely efficient, is fast and it is free from any electromagnetic interference.
It is possible to measure the following sizes:
-
- Temperature
- Humidity
- Refraction index and PH
- Level of the flow of liquids
- Radiation
-
- Distortion
- Movement
- Inclination
- Rotation
- Acceleration
-
- Vibration
- Magnetic field
- Electrical field
- Acoustic field
- Strength and pressure
