Many Telemac and Smartec products were used for the Olkiluoto Nuclear power plant project: more than 500 conventional sensors (vibrating wires strain gauges and load cells), pendulum systems, temperature and humidity sensors, rotary switching panels, and complete central measurement units. In addition, over 1,500 meters of distributed fiber optic sensors (for the measurement of strain and temperature along the liner), and a central measurement unit with customized software for the treatment, visualization, and storage of the measurement data were used to monitor the Olkiluoto Nuclear power plant.
