CRD-rebar

product description:

CRD-rebar is a Fibre Bragg Grating sensor mounted on the steel reinforcement bar of interest. The sensor can be installed both before the rebar placement or on already placed rebars in the construction site. After the concrete has cured, the CRD-rebar sensor measures the reinforcement bar's strain.
