EpsilonSensor

EpsilonSensor enables accurate strains and precise crack measurements over its entire length due to the perfect bonding with the specimen. Specially selected composite material provides unique strain reading precision and sensitivity. EpsilonSensor is a perfect solution for laboratory applications, designed for direct embedding into the newly-designed structural members (made of concrete or soil) or to be installed within existing structural members (e.g. reinforced or prestressed concrete girders). Lightweight, low bending radius and extremely low stiffness allow the sensor to be installed easy and to not influence the behavior of the specimen.

SENSOR ADVANTAGES:

STRAIN AND CRACK MEASUREMENT ALONG THE ENTIRE LENGTH of the sensor, optionally also temperature
NO SENSOR INFLUENCE on the monitored structural member (negligible stiffness)
MONOLITHIC SECTION WITH NO INTERMIDIATE LAYERS providing accurate readouts
SHARP and PRECISE view of any local phenomena, especially cracks in concrete
EASY INSTALLATION – lightweight sensor, ready to use when unrolled from the drum
RESISTANT TO ENVIRONMENTAL CONDITIONS, including electromagnetic fields and lightning strikes

APPLICATIONS:

LABORATORY REASERCH – especially crack observation in concrete
STRUCTURAL HEALTH MONITORING of engineering structures
reinforced and prestressed CONCRETE specimens

Application of DFOS strain Sensors for the structural health monitoring of real engineering structures allows for strain measurements over entire length with a spatial resolution starting from 5 mm. The key thing is to use sensors which are accurate and reliable. EpsilonSensor provides new opportunities in the quantitative and qualitative assessment of strains and cracks in concrete. It allows for the precise detecting the cracks locations and estimating their actual width during changing environmental conditions over long term.
