Sensors / intrinsic
Optical fibers are transducers and thus both sensors and the line for signal transmission. Examples are:
- fiber optic pressure sensors
- fiber optic strain sensors
In these sensors, the change in the optical fibers, for example due to pressure or tension, is accompanied by a change in transmission or a shift in wavelength, which is ultimately evaluated by the receiver electronics.
Sensoren / extrinsisch
Here, the optical fiber merely serves as a transmitter of the measured variable detected by the sensor, which must be available as an optical signal. Examples are:
- fiber optic temperature sensors (pyrometers)
- fiber optic light barriers
In these sensors, states are detected by transmitter and receiver electronics, e.g. in high-temperature applications or in automation technology.
Application / industrial
You can achieve advantages through fiber optic technology in these areas:
- Automation technology: process control
- Industrial process control: transmission and reflection light guides
- Detection of smallest objects
- High-temperature applications: steelworks, coking plants
- Explosive environments
- Fire protection: flame monitoring
- Temperature measurement with pyrometers
- Liquids, chemicals: level measurement, leak detection
- Industrial lighting: illumination of critical process areas
- Microscopy: single/multi-arm gooseneck or ring light guides
- Laser technology: fiber optic beam guidance systems for high-power lasers in material processing
