The Role of Ruifen Vibration Sensors in Compaction Quality Monitoring and Analysis Systems

With the advancement of information technology, digitalization and informatization have become integral to the entire lifecycle of engineering projects. In recent years, the rapid development of IoT and mobile technologies has driven innovative applications of high-precision measurement, positioning, and intelligent technologies in construction process control. These innovative products provide scientific and effective means to control construction quality, enhance efficiency, and ensure safety.
Compaction is a primary construction method for infrastructure projects such as hydropower stations, airports, high-speed railways, and transportation networks, encompassing processes like soil-rock compaction and roller-compacted concrete. While the degree of compaction serves as the core metric for evaluating quality and results, parameters such as layer thickness, number of passes, and vibration frequency are critical control indicators during the process. Traditionally, quality monitoring relied on manual measurement of layer thickness, manual logging of passes, and post-compaction sampling tests for compaction degree; these methods were not only inefficient but also failed to provide a comprehensive assessment of quality. Although digital monitoring products and solutions based on GPS and related sensor technologies have emerged recently, they often entail high costs, and domestic enterprises frequently lack independent intellectual property rights for the core technologies.

Ruifen Technology’s vibration sensors AKC378  play a pivotal role in real-time compaction quality monitoring and analysis systems. By utilizing vibration frequency and amplitude data, the sensors monitor parameters such as the number of passes, speed, and excitation force in real-time, ensuring the roller operates according to specifications and meets design requirements; the system can also calculate the instantaneous excitation force based on amplitude and frequency. (Vibration frequency refers to the number of oscillations over a specific period, while vibration amplitude corresponds to the maximum acceleration.)

Installed on the roller drum, the product transmits data in real-time, providing construction guidance and early warnings for anomalies—such as deviations in compaction speed or layer thickness—to assist the operator in controlling the machinery.

Typical Applications

• Industrial vibration monitoring
• Low-frequency vibration monitoring
• Bridge impact monitoring
• Structural health monitoring
• Machine control

Can AKC378 be used for road roller vibration monitoring?

Yes. AKC378 can be integrated into road rollers to monitor three-axis vibration during compaction operations. Its 4-20mA analog output allows the vibration signal to be connected to industrial control or monitoring systems.

What can AKC378 monitor on a road roller?

AKC378 can monitor vibration conditions of the road roller during operation, helping detect abnormal vibration, support machine control and provide vibration data for equipment condition monitoring.

Why use a 4-20mA vibration sensor on a road roller?

The 4-20mA output is widely used in industrial control systems and is suitable for transmitting sensor signals to control units or monitoring equipment over relatively long cable distances.
