광섬유 브래그 격자 응력 센서 - FBG 응력 게이지 - 볼트 및 앵커 로드 응력 감지

본 제품은 응력 측정을 위해 무봉강관 또는 고분자 재료로 캡슐화된 FBG 응력 센서(FBG 응력 게이지)입니다. 응력 측정을 위해 테스트 대상물에 삽입하는 단일 종단 구조로 설계하거나, 직렬로 다점 응력 측정을 가능하게 하기 위해 침지 또는 표면 부착을 위한 이중 종단 구조로 설계할 수 있습니다. 본 제품의 구조는 다양한 광섬유 격자 변형 센서와 동일합니다.

FBG 응력 센서의 원리:

The FBG stress sensor is a derivative application of the OFSCN® FBG 변형 센서. 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 변형 센서. 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.

FBG 응력 센서의 구조 및 구성:

OFSCN® Capillary FBG 응력 센서 (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.

산업 장비, 볼트, 부품, 크레인, 콘크리트, 철도, 군사 장비, 항공우주 및 기타 분야에서 단일 지점 또는 분산 응력 모니터링 및 측정(인장 및 압축 포함)에 널리 사용될 수 있습니다.

FBG 응력 센서의 배치 방법:

OFSCN® Capillary FBG 응력 센서 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 응력 센서 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 응력 센서 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

FBG 응력 센서의 장점:

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 그리고 rapid response (millisecond-level response).

Compared to piezoelectric stress sensors based on current, resistance, voltage, capacitance, and other technologies, the OFSCN® Capillary FBG 응력 센서 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 응력 센서 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 응력 센서 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.
