What are the precautions for using the angle calibrator for the rotary compaction tester?

The rotary compaction apparatus angle calibrator uses an 8-inch touch screen as the interface for setting instrument technical parameters. The interface is clear, highly visible, and facilitates easy human-machine interaction. The system features comprehensive protection functions and boasts high reliability. The control system is based on a PLC, with a reserved computer interface. Through the computer, pressure and displacement data of the specimen can be collected in real time, and corresponding experimental curves can be plotted according to user requirements.

The rotary compactor angle calibrator applies a vertical stress—typically 600 kPa—to a known mass of asphalt mixture placed in a mold with an inner diameter of either 100 mm or 150 mm, via end plates. The upper and lower end plates remain parallel and horizontal, while the longitudinal axis of the mold rotates at a fixed angle relative to the vertical direction. During compaction, the sample height is automatically measured, and the density and void content of the mixture are calculated in real time. Throughout the compaction process, test data are displayed on the screen in both graphical and tabular formats and are stored in an Excel-compatible file format. The operator can select either the number of compaction cycles or the target density or void content of the compacted mixture.

The rotary compaction angle calibrator is a next-generation rotary compactor that can operate using either internal or external rotary compaction angles without the need for calibration. It allows the rotary compaction angle to be adjusted to the desired value, ensuring that the rotary compactor can meet a wide range of future requirements. This device can be equipped with a load sensor to measure the force required to rotate the sample, and its shear measurement apparatus and internal rotary shear angle are standardized by the afls1 internal angle measurement device.

Brief introduction to the product features of the rotary compactor angle calibrator:

The rotary compaction instrument angle calibrator features comprehensive protection functions and is capable of operating under complex working conditions.

The rotary compaction tester’s angle calibrator uses an industrial touchscreen as the human-machine interface platform. The interface is clear and highly visible. It features a Chinese-language interface, making parameter settings straightforward, and displays process data in real time—including the number of rotations, displacement data, and density change curves. A computer interface is also provided, allowing users to download test data from the computer and store/print it in Excel format, spreadsheets, and trend charts.

Precautions for using the rotary compactor angle calibrator:

1. When using the equipment, carefully read the technical manual to familiarize yourself with the technical specifications, operational performance, usage methods, and precautions, and strictly follow the steps specified in the instrument’s operating manual.

2. Personnel using the equipment must operate under the guidance of trained personnel and may only operate independently after becoming proficient.

3. The instruments and equipment used in the experiment should be arranged and placed appropriately to facilitate operation, observation, and data recording.

4. Before powering on electronic instruments and equipment, ensure that the power supply voltage meets the input voltage specifications required by the instrument or equipment. For instruments and equipment equipped with three-wire power plugs, insert the plug into a power outlet and connect it to protective earth grounding to ensure safety.

5. When using the device, its input signal or external load should be kept within the specified limits; overloading is strictly prohibited.

6. Optical and chemical instruments and accessories should be handled with care to avoid vibrations. Do not touch the surfaces of optical glass with your hands. If dust or dirt is found, do not wipe it off with your hands or a cloth; instead, use the appropriate products or tools to remove it.
