6000με Fiber Bragg Grating Strain Sensor - FBG Strain Gauge - Metal Encapsulation - High Temperature FBG Strain Sensor

The product is a fiber Bragg grating strain sensor (FBG strain gauge) encapsulated in high elastic alloy tube, used for strain measurement. In most cases, it is a single-segment single-ended structures, or it can be produced as a multi-segment single-ended structure. In a few cases, it can also be a double-ended structure. The sensor can be customized as radiation-resistant fiber Bragg grating strain sensor or high-temperature resistant fiber Bragg grating strain sensor. The deployment method of the product depends on the supporting fixtures, which can be directly inserted into the test object, or installed by surface welding with corresponding fixtures, bolted with drilled holes for fixation, adhesive surface mounting, tied with straps for fixation, or fixed with clamps, among various installation methods. This product is a basic structural product, which can be calibrated as a FBG displacement sensor, or used as a FBG stress sensor.

OFSCN® 6000με FBG Strain Sensor Product Summary:

The OFSCN® 6000με FBG Strain Sensor (FBG strain gauge) is composed of fiber optic connectors (FC, SC, LC, ST, etc.), high elastic alloy tubes, and single-point/Multi-point FBG encapsulation.

It can also be customized as radiation-resistant FBG strain sensor or high-temperature resistant FBG strain sensor.

This product features a small size, lightweight, high tensile and compressive strength, waterproof, moisture-proof, and fully sealed characteristics. By utilizing the strain characteristics of the FBG, this sensor can be inserted, clamped, surface-mounted, glued, or embedded into the measured structure to perform strain detection and monitoring.

It can be widely used in various fields such as industrial equipment, bolts, components, cranes, concrete, railways, military equipment, aviation, aerospace, etc., for single-point or multi-point quasi-distributed strain monitoring and measurement.
