Faser-Bragg-Gitter-Spannungssensor - FBG-Spannungsmesser - Bolzen- und Ankerstab-Spannungsdetektion

Dieses Produkt ist ein FBG-Spannungssensor (FBG-Dehnungsmesser), der in nahtlosen Stahlrohren oder Polymermaterialien zur Spannungsmessung eingekapselt ist. Er kann als einseitige Struktur zum Einsetzen in das zu prüfende Objekt zur Spannungsmessung oder als zweiseitige Struktur zum Eintauchen oder zur Oberflächenbefestigung konzipiert werden, um eine Mehrpunkt-Spannungsmessung in Reihe zu ermöglichen. Die Struktur dieses Produkts ist die gleiche wie die verschiedener faseroptischer Gitterdehnungssensoren.

Prinzip des FBG-Spannungssensors:

The FBG stress sensor is a derivative application of the OFSCN® FBG-Dehnungssensor. The relationship between them is as follows: Stress of the tested object = Elastic modulus of the tested object × Strain. Therefore, the structure of the FBG stress sensor is the same as the OFSCN® FBG-Dehnungssensor. However, since the tested materials may vary for customers who purchase FBG stress sensors, the calibration formula is given in terms of micro-strain and corresponding wavelength.

Struktur und Zusammensetzung des FBG-Spannungssensors:

OFSCN® Capillary FBG-Spannungssensor (FBG stress gauge) consists of fiber optic connectors (FC, SC, LC, ST, etc.), different types of encapsulation materials, and FBG. When used together with FBG demodulators, it forms a FBG stress sensing system.

Er kann weit verbreitet für die Einzelpunkt- oder verteilte Spannungsüberwachung und -messung (einschließlich Zug und Druck) in Industrieanlagen, Bolzen, Teilen, Kränen, Beton, Eisenbahnen, Militärausrüstung, Luft- und Raumfahrt und anderen Bereichen eingesetzt werden.

Bereitstellungsmethoden für FBG-Spannungssensoren:

OFSCN® Capillary FBG-Spannungssensor has the characteristics of small size, light weight, high tensile strength, high compressive strength, water resistance, moisture resistance, and full sealing. By utilizing the strain characteristics of FBG, the sensor can be inserted, clamped, attached to the surface, bonded, or embedded into the tested structure for stress detection and monitoring

When combined with other tested objects, the OFSCN® FBG-Spannungssensor can be used as an anchor rod stress sensor, surrounding rock stress sensor, borehole stress sensor, steel support stress sensor, blade stress sensor, blast stress sensor, and more.

The OFSCN® Capillary FBG-Spannungssensor can be installed by directly fixing and clamping both ends, welding, bundling, adhesive surface mounting, adhesive encapsulation after insertion into the tested object, or direct installation in concrete, among other methods. In some special applications, special fixtures can be designed to assist in displacement measurement

Einsatzumgebung und Anwendungsindustrien des FBG-Spannungssensors:

OFSCN® Capillary FBG Stress Sensors are commonly used in various environments such as dams, bridges, tunnels, large crane booms, large machinery und equipment, interior und exterior surfaces of buildings, concrete surfaces und interiors, highway roadbeds, tunnels, und locations prone to landslides. They can also be used for testing various new materials.

Einsatzumgebung und Anwendungsindustrien des FBG-Spannungssensors:

Je nach den Eigenschaften des Prüfmaterials oder -objekts und der Formel 'Spannung des Prüfobjekts = Elastizitätsmodul des Prüfobjekts × Dehnung' können die folgenden faseroptischen Gitterdehnungssensoren zur Spannungsmessung verwendet werden:

1、Faser-Bragg-Gitter-Dehnungssensor - FBG-Dehnungsmesser - Metallkapselung, Messbereich: 2500με

2、Hochbereichs-Faser-Bragg-Gitter (FBG) Dehnungssensor - FBG-Dehnungsmesser - Metallschutz, Bereich: 6000με/8000με

3、Ultra-Hochbereichs-Faser-Bragg-Gitter-Dehnungssensor - (FBG) Dehnungsmesser - 3% bis 40% Verformung - Bereich 30000με

Vorteile des FBG-Spannungssensors:

Compared to stress sensors based on vibrating wires, the OFSCN® Capillary FBG Displacement Sensor uses the displacement of the internal FBG as a reference for displacement detection. It is not affected by environmental conditions such as air quality (haze, rain, snow, obstruction), ensuring accurate testing und rapid response (millisecond-level response).

Compared to piezoelectric stress sensors based on current, resistance, voltage, capacitance, and other technologies, the OFSCN® Capillary FBG-Spannungssensor is based on fiber optic communication and sensing. Therefore, it is immune to electromagnetic interference and can operate in various strong and weak electromagnetic environments.

Compared to stress sensors based on various PCB circuits, the OFSCN® Capillary FBG-Spannungssensor can be customized in length, offering flexibility in usage with both long and short lengths. It can monitor a wide range of environments or objects, saving the number and cost of sensors used.

The OFSCN® Capillary FBG-Spannungssensor is a digital, recordable, and network-enabled sensor. Changes in length and displacement can be monitored without the need for visual observation. The FBG stress sensing system can monitor length changes and displacement information over large spaces, long distances, and multiple targets, with a wide coverage range.
