Description
Vibrating Wire Strain Gauge – Model EDS-20V-E
The EDS-20V-E vibrating wire strain gauge is designed for accurate measurement of strain in pile foundations, tunnel segment linings, and reinforced concrete structures.
It is suitable for installation in soil, concrete, and rock, making it ideal for both geotechnical and structural monitoring applications.
The sensor features a stainless-steel body with hermetic sealing and waterproof construction, ensuring long-term stability and reliable operation under harsh environmental and underground conditions.
It measures strain by detecting changes in the tension of a vibrating wire, providing high accuracy, excellent long-term performance, and immunity to signal loss over long cable lengths.
