Rebar Detector is a kind of conventional measuring instrument. Rebar Detector is an automated, high-precision optical instrument integrating light, machine, electricity, and calculation. Based on the electronic intelligence of Rebar Detector, it adopts electronic subdivision, Control processing technology and filtering technology to achieve intelligent measurement readings. It can be widely applied to the three or four triangulation control surveys in countries and cities. It can be used for engineering measurement in railways, highways, bridges, water conservancy, mines, etc. It can also be used for the installation of buildings and large-scale equipment. It can be applied to cadastral surveys and topographic surveys. And a variety of engineering measurements.

Factors that determine the accuracy of Rebar Detector:

Due to processing technology and other reasons, the accuracy of Rebar Detector is mainly determined by the following factors:

1. Imaging error: The imaging quality of the telescope includes the telescope discrimination rate and aberrations, and the visual axis variation error when focusing the telescope;

2. Shafting error: Including the manufacturing accuracy of the shaft, the clearance between the shaft and the shaft, the verticality of the vertical shaft and the horizontal shaft, the verticality between the sighting shaft and the horizontal shaft, the vertical shaft not plumb, the sighting department Correctness of rotation, etc.;

3. Eccentricity difference: Eccentricity difference includes the misalignment of the reference part, eccentricity of the horizontal dial, and eccentricity of the verticality;

4. Compensation accuracy of the vertical index automatic compensator;

5. Accuracy of code disk or grating disk and division error of micrometric grating;

6, the stability of the instrument base;

7, the reliability of electrical components;

8, the orthogonality of the phase.
