Distributed fiber optic sensors for measuring strain and temperature.

 

 

We present the solution of distributed fiber optic sensor (DFOS)

technology to measure the temperature and strain of reinforced

concrete test piles during construction and during static load tests

 

 

 

 

 

 

Successful development of Pulse Pre-Pump BOTDA technique,  simultaneously

achieving 10 cm spatial resolution and ± 0.0025% strain measurement accuracy.

 

 

 

 

 

Fiber optics state monitoring can be applied throughout plant

facilities, improving the equipment reliability and increasing the

effectiveness of plant maintenance.

                           

 

 

 

 

Depending on the used equipment and cables can be detected:

– Changes in temperature, pressure, deflection of the fibers,  changes in acoustic

– Monitor the routes of transmission pipelines for water, gas or  chemical

– To oversee the industrial areas, warehouses, transport routes

– Monitor industrial infrastructure

– Detect tectonic movements, etc.
