The crack meter is a typical application of LVDT linear displacement sensor in the field of civil engineering quality inspection, which could be used to detect the opening of cracks in the surface of concrete or rock, etc.. The LVDT crack meter, using the principle of variable differential transformer, converting the quantities of crack to electrical signals could be recognized by the instrument, and the output signal has the voltage signal, current signal and digital signal.

LVDT crack meter not only has high accuracy and long working life, could be used in harsh and complex environment, but also has strong anti-interference ability, and is convenient to use and install. Such as the bridge damage and fracture, ordinary manual monitoring is difficult to detect, in this kind circumstance, install an LVDT displacement sensor to detect the cracks open degree precisely, at the same time, through the algorithm, also can be used to detect bridge deflection.
