Introduction: DM-SL series magnetostrictive static level is a special precision instrument for measuring the relative elevation change between each measuring point of foundation and building. It is widely used in the precise measurement of settlement or buoyancy of basic filling structures such as hydropower station dams, deep foundation pits, highways, bridges, embankments, oil and gas pipelines, oil storage tanks, etc. Features: 1. Magnetostrictive sensing principle, 4-20mA standard signal output; 2. High measurement accuracy, long-term stable performance, sturdy and reliable; long service life. 3. Large measuring range and high sensitivity. 4. Water-proof, corrosion-resistant, long-term reliability. 5. Suitable for telemetry and automated data collection. 6. The installation is convenient, and there are no strict requirements on the elevation between different installation points.
