Magnet extensometer ASM-001
Precise Monitoring of Ground Settlements and Structural Displacements
The ASM-001 Magnetic Extensometer is a highly accurate instrument designed to measure vertical displacements and settlements in the ground and structures. It is widely used in geotechnical and civil engineering applications for monitoring embankments, railways, foundations, earth-fill dams, and tunnels. Using a series of magnetic rings connected to the soil by steel springs, the extensometer provides reliable and cost-effective data on ground movements, ensuring long-term stability in infrastructure projects.
Key Features:
- Access Tube: 3/4" diameter
- Corrugated Sheath: 55 mm
- Probe Accuracy: ±1 mm
- Cable Length: 30-300 m
- Measurement Method: Magnetic rings and probe for accurate displacement readings
- Durable Construction: Suitable for harsh environments
- Long-Term Monitoring: Designed for reliable, continuous data collection
Applications:
- Monitoring of embankments and railways
- Monitoring subsidence of foundations
- Earth-fill dam settlement tracking
- Measuring vertical displacement in tunnels
- Settlement monitoring of residential and historical buildings
Functionality: Structural and geotechnical monitoring

Magnetic Extensometer ASM-001
Reliable settlement monitoring for safe, long-term infrastructure

In geotechnical engineering, early detection of ground settlement and vertical displacements is essential to safeguard infrastructure performance. Accurate measurement of soil and structural movements provides engineers with critical insights into ground behavior under load, seasonal variation, or nearby construction activity. When integrated with data logging systems, this information supports long-term asset management strategies, enhances safety, and reduces maintenance costs. It’s not just monitoring – it’s a proactive approach to resilient infrastructure.
