The material of the sensor bodies is a robust hard plastic manufactured by injection molding. The sensors are encapsulated with epoxy resin, and there is a granular layer on top for better adhesion to the concrete. The moisture sensor measures between two stainless steel rings. The wires on the corrosion sensor mimic the rebar using S235JR+AR steel. Through various tests, this wire was chosen for its appropriate material properties and thicknesses.
Important
This is an early warning system that indicates the progression of corrosive activities and informs of their speed so that we can receive information and act efficiently. The aim is not to measure the condition of the reinforcement but to warn of a danger to the reinforcement.
