Reservoir dam liquid level detection and dam displacement measurement
I. Overview
Magnetostrictive displacement sensors are widely adopted in earth-rock dam liquid level detection and structural safety monitoring due to their:
Long-term stability and durability (decade-long service life).
Minimal maintenance (no periodic calibration or manual intervention).
Seamless integration with(water conservancy) automation systems for real-time monitoring of:
Dam seepage
Crack propagation
Gross displacement
II. Key Features & Applications
1. Liquid Level & Seepage Monitoring
High linearity (±0.05% FS typical) and stable signal transmission.
IP67-rated waterproofing for harsh environments (e.g., submerged or humid conditions).
Plug-and-play installation with compatibility for水利 SCADA systems.
2. Dam Displacement Measurement
Non-contact measurement eliminates mechanical wear, ensuring longevity.
Absolute position output (no zeroing after power cycles).
Robust against contaminants (dust, oil, moisture) with IP67 protection.
III. Technical Advantages for Civil Engineering
Precision & Reliability
Accuracy: Up to ±0.01% FS (for high-end models).
Repeatability: <0.001% FS.
Flexible Outputs
Analog (4–20mA, 0–10V) or digital (SSI, Modbus, PROFIBUS).
Environmental Resilience
Operating temperature: Typically –40°C to +85°C.
Vibration/shock resistant (e.g., 100g shock tolerance per IEC 60068-2-27).
IV. Deployment Scenarios
Seepage Monitoring: Vertical installation in dam boreholes to track water table shifts.
Displacement Detection: Horizontal mounting on dam surfaces or joints to measure deformation.
Integration: Direct linkage with水利 IoT platforms for predictive maintenance.
V. Cost Efficiency
Lower TCO (Total Cost of Ownership) vs. LVDTs or ultrasonic sensors (no recalibration/replacement parts).
Reduced downtime with fail-safe outputs.
