Product Introduction

The DY-GJC2 Steel Rule Calibration Device is designed and developed by Taiande Machinery and Electrical Equipment Co., Ltd. in accordance with the new JJG4-2015 "Steel Rule Calibration Specification." This calibration device is used for the calibration of steel rules. The calibrator can be used to check the indication error of conventional measuring tools such as steel rule, steel tape rule, depth measurement oil rule, steel hoop rule, fiber rule, and steel plate rule (the steel plate rule can only be used for comparative testing and cannot establish a standard), etc. With a zero-point calibration bench, it can also be used to compare the zero-point deviation of depth measurement oil rules.

Key Features

1) This calibration instrument features a simple structure, easy installation, and an aesthetically pleasing and practical design.

2) The main components (weight hammer and handle) are electroplated, featuring a bright and elegant finish.

3) Equipped with a heavy hammer unloading device, it allows for easy control of loading and unloading.

4) Configure a reading microscope for conveniently and clearly displaying the error of the inspected ruler.

5) The reading microscope is equipped with an illumination system, ensuring the image is extremely clear.

6) The reading microscope and lighting equipment are mounted on the measuring cart for easy operation. The cart can be completely removed for convenient storage and maintenance.

7) Using the lower shaft to lift the standard ruler and the inspected ruler eliminates the friction between the ruler belt and the table surface, thereby improving the detection accuracy.

Technical Specifications

The device can detect: Grade 1 and 2 standard steel measuring tapes. Deep-sea steel measuring tapes (oil measuring tapes). Fiber measuring tapes. Measuring ropes and other large-scale measuring tools of the tape category.

Calibration Bench Length: 5.3m (Overall length approx. 5.9m, can be extended in 5m increments up to 50m as per customer request)

2. Effective Detection Length: 5m (Segmented method for measurement range: 5-200m)

3. Standard steel ruler accuracy: (0.02 + 0.02L) mm

4. Inspection of guide rail straightness on the measuring table: ≤0.3mm/m

5. Overall static friction force of the calibration table: ≤4N

6. Instrument Resolution: 0.01mm

7. Instrument features built-in lighting

8. Reading Microscope: 20X, 0.01mm

Basic Configuration: 1 standard 5m ruler, 1 calibration bench, 1 small pulley, 1 reading microscope, 2 ruler clips, 2 5kg lead weights, 1 digital display box, 1 power supply set.

The device utilizes a grating displacement sensor along with a standard steel ruler for data collection of the instrument's measurements. The PLC data processing directly provides the measurement results, thereby reducing manual labor intensity.
