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.
Based on your description of the product’s versatility in installation—ranging from surface welding and bolting to adhesive mounting—this sensor is clearly designed for complex structural health monitoring.
To provide more specific technical insights for potential applications, I would like to clarify a few performance parameters:
Temperature Range: You mentioned that it can be customized as a high-temperature resistant version. What is the maximum operating temperature this alloy tube encapsulation can reliably sustain without experiencing strain transfer loss or creep?
Measurement Range: For the standard high elastic alloy version, what is the maximum measurable microstrain (με) range?
Below is a standard reference image of the product structure for technical clarity:
As a pre-sales engineer, I am available to discuss the mechanical integration and strain transmission efficiency of this sensor for specific engineering environments.
