A monitoring system (1), particularly for damage to structures and buildings, comprising at least one apparatus (2a, 2b, 2c) for measuring cracks (10) of a structure (3a, 3b, 3f), the apparatus (2a) comprising a first fixed element (21), which is integral with a structure at a first zone (31) of the crack (10), and a second fixed element (22), which is integral with the structure (3a) at a second zone (32) of the crack (10), which is opposite to the first zone (31), the first fixed element (21) having a portion (23) that is adapted to engage the second fixed element (22) so as to straddle the crack (10); the system comprises a first element for detecting displacement along a first detection direction (101) which operates between a first abutment region, defined on the first fixed element (21), and a second abutment region rotatably supported about a first pivoting axis (103) by the second fixed element (22), the apparatus (2a) furthermore comprising a second element for detecting displacement along a second detection direction (102), which is substantially perpendicular to the first detection direction (101), the second detection element operating between a third abutment region, defined on the second fixed element (2), and a fourth abutment region rotatably supported, about a second pivoting axis (104) parallel to the first pivoting axis (103), by the first fixed element (21). |
