The steel ruler calibration device has completely replaced the traditional method of detecting third class metal line gauges used for detecting steel rulers and other line gauges. The verification table adopts a one meter grating displacement sensor as the working standard based on the rock workbench. Configuring an industrial CCD camera allows for very clear and intuitive observation and measurement. The displacement of the digital display instrument grating ruler clearly displays the actual measurement results. With the assistance of auxiliary devices, this calibration table can quickly and conveniently detect steel rulers larger than one meter.
This calibration device is used to calibrate steel rulers and is a precision engraved metal ruler with a reading magnifying glass and a thermometer. Commonly used to check the distance between contour points, control points, and coordinate network points, it is specified in the national leveling measurement standards as a standard ruler for calibrating leveling scales. High precision, high stability, high clarity, precise and consistent engraving line width and spacing.
Characteristics of steel ruler calibration device:
1. The engraved surface of the third class line ruler shall not have scratches, bumps, rust, or other phenomena. The engraved lines should be uniform, perpendicular to the edge of the ruler and extend to the edge of the ruler, without any broken or heavy lines.
2. In the verification state, the engraved lines should be clear throughout the entire process when observed through a reading microscope.
3. The scale digits of the third class line ruler should be of moderate size, not affecting the engraved lines, and consistent before and after.
4. The accessories of the third class line ruler (thermometer, magnifying glass) should be complete, and the magnifying glass should have clear imaging and flexible sliding on the guide rail.
5. The first calibration of the third-order line ruler should meet the above requirements, and subsequent calibration and in-service testing are allowed to have appearance defects that do not affect the metrological performance.
6. For newly made third-order linear rulers, the manufacturing material, manufacturer or logo, and factory number should be indicated on the back flange of the ruler; The name and manufacture of the measuring instrument should be indicated on the measuring box.
7. Two copies of equipment user manual, one copy of product qualification certificate, one copy of packing list, and each component including inspection certificate.
