The products being developed by GESO are based on the fibre optic Distributed Temperature Sensing Technology (DTS). This technology provides temperature readings along the length of an optical fibre with a high temperature resolution as well as a high spatial resolution. The temperature is measured simultaneously at regular intervals of normally 1 meter over the whole length of the fibre; the temperature over each metre being averaged.>
Advantages of the Measurement Technology
- No interference with the temperature field when measuring.
- The sensor cable is inherently electrically passive; therefore it can be used as a temperature sensor in explosion-prone environments as well as in electromagnetic fields.
- The sensor cable has a very long life span.
- The cable can be employed in structures which will be inaccessible at a later time.
- The measuring technology can be used as a temporary installation or as a permanent online monitoring service, which can also be integrated into operation control systems and data logging systems.
