Monitoring the thermal expansion of concrete walls

Electrothermal energy storage systems are filled with volcanic rock, which absorb excess energy in the form of heat and release it back into the power grid when needed. The lava stones are filled into a container made of reinforced concrete. Due to thermal expansion, the reinforced concrete tank must be permanently monitored. For this purpose, optoNCDT ILR2250 laser distance sensors detect the smallest movements of the reinforced concrete walls. The measured values are transmitted to a PLC via the analog interface. If the setpoint is exceeded, the energy supply to the stones is stopped immediately.
