Abstract
The utility model relates to a reinforced concrete protection layer thickness detector. The reinforced concrete protection layer thickness detector includes a probe, a detection device and a display device that are in signal connection successively. The probe includes a magnet and a spring connected together. According to the utility model, the magnet and the spring are arranged in the probe. The spring is fixed and the magnet is connected with the spring flexibly. The length of the spring is measured by utilizing a spring scale principle, so that the magnitude of forces can be obtained and the thickness of the reinforced concrete protection layer can be thereby obtained through conversion.
