This product is a high-range fiber bragg grating strain sensor (FBG strain gauge) used for strain measurement. It can be used in a single-ended structure, where it is inserted into the object to be measured for strain measurement. It can also be used in a double-ended structure, where it is fixed with a fixture or bonded directly to the surface for strain measurement, enabling multi-point strain measurement when connected in series. The structure of this product is the same as that of fiber bragg grating stress sensors.
Product Overview:
The OFSCN® high-range fiber bragg grating strain sensor (FBG strain gauge) consists of fiber connectors (FC, SC, LC, ST, etc.), high elastic materials, and single-point FBG encapsulation. Depending on the materials used, it can work at room temperature or a maximum high temperature of 120 degrees Celsius (customizable upon request).
This product is characterized by its small size, light weight, high tensile and compressive strength, waterproof and moisture-proof properties, and full sealing. By utilizing the strain characteristics of FBG, this sensor can be inserted, welded, bonded, or adhered to the internal or surface of the test structure for strain detection and monitoring.
It can be widely used in various fields such as industrial equipment, metal, cranes, concrete, railways, military equipment, aerospace, etc., for single-point or multi-point quasi-distributed strain monitoring and measurement.
