Description

Carbonization depth measuring instrument Technical Field The utility model relates to the technical field of carbonization detection devices, in particular to a carbonization depth measuring instrument. Background The current carbonization depth measuring instrument comprises a probe and a cross rod, wherein the cross rod is driven to swing through sliding of the probe during measurement, and the carbonization depth of concrete is calculated through detecting the swing range of the cross rod. The related art can refer to the chinese patent with publication number CN103353281B to disclose a measuring device, in particular to a digital carbonization depth measuring instrument. The digital carbonization depth measuring instrument comprises a shell, a grating, a photoelectric sensor assembly, a display screen and an operation key, wherein a rope hanging hole is formed in the upper left side of the shell, a storage battery is arranged in the upper side of the shell, the grating is arranged on the lower side of the storage battery, the photoelectric sensor assembly is arranged on the upper side of the grating, a circuit board is arranged on the lower side of the grating, the display screen and a singlechip are arranged on the circuit board, the operation key is arranged on the lower side of the display screen, a measuring key is arranged on the upper left side of the operation key, a contact pin is arranged on the lower side of the operation key, the contact pin is connected with the photoelectric sensor assembly through a swinging lever, a photoelectric switch is arranged on the swinging lever, and a front cover is arranged on the lower side of the shell. The displacement signal conversion device has the advantages of simple structure, convenience in use, safety and reliability, reduction of the cost of electronic devices and matched circuit boards, capability of directly converting the displacement signal into an electric pulse signal, and no unstable factors of temperature drift, humidity drift and time drift. For the above related art, in the process of using the carbonization depth measuring instrument, because concrete is measured, a small amount of dust and oil dirt inevitably enter the measuring instrument in the measuring process, the measuring accuracy of the grating highly depends on the definition of the optical path, and the dust adheres to the surface of the grating line to shield the light, so that the pulse signal may be lost or distorted.
