DESCRIPTION
The BA-OFS30 fiber optic grating welded strain sensor is a high-performance strain gauge developed for measuring the stress and deformation of bridge steel box beams, seismic dampers, metal anchors, and other metal structural components. This product is all made using welding technology, with high reliability and long-term stability, suitable for long-term strain monitoring of metal materials.
Product Features
Compact structure, convenient and fast installation, and direct and accurate strain response;
Characteristics of fiber optic sensors:
Intrinsically safe, resistant to electromagnetic interference, corrosion, pollution, and lightning strikes, suitable for use in harsh conditions such as strong electromagnetic interference, high lightning strikes, flammability, and explosiveness;
The layout is simple, and the bidirectional cable can be connected in series or parallel. A single channel can measure 12 sensors, making networking convenient and improving the utilization rate of the demodulator;
Demodulators for general use with other types of sensors, with good compatibility;
Made with a special metallized grating, it has long-term zero stability and minimal temperature drift.
