Technical Specifications
Product Overview
Extended range extensometer for large deformation monitoring in deep boreholes.
Working Principle
This displacement transducer utilizes Linear Variable Differential Transformer (LVDT) technology or potentiometric principles to convert mechanical displacement into proportional electrical signals. The LVDT design employs three coils and a movable magnetic core, generating an AC voltage output that varies linearly with core position. This contactless measurement principle ensures infinite resolution and exceptional longevity. The sensor's robust construction withstands harsh industrial environments while maintaining measurement accuracy. Advanced signal conditioning electronics provide temperature compensation and noise rejection, delivering stable and repeatable measurements across the full operating range.
Application Scenarios
Essential for structural health monitoring of bridges, buildings, and dams where precise displacement measurement is critical for safety assessment. Widely used in material testing machines for measuring specimen deformation, in hydraulic cylinder position feedback, and in automated manufacturing equipment for quality control. The sensor supports applications in civil engineering, aerospace testing, automotive manufacturing, and research laboratories. Particularly valuable for long-term monitoring installations where reliability and accuracy are paramount.
Technical Advantages
