Import Fbg Interrogator — Buy in Bulk from Supplier in Hong Kong

Alxenses Co., Ltd. supplies an FBG interrogator designed for real-time, multi-point measurement of strain and temperature using fiber Bragg grating arrays. The device captures spectral shifts from up to 100 gratings simultaneously, converting wavelength changes into precise physical parameters. It operates without electrical components near the sensing point, making it suitable for explosive or high-electromagnetic environments.

The interrogator uses a tunable laser source and high-speed spectrometer with a resolution of 0.1 pm and a scan rate of up to 1 kHz per channel. Typical dynamic range is ±20,000 με for strain and ±100°C for temperature. It supports both single-mode and polarization-maintaining fiber inputs, with software that auto-maps grating locations and compensates for cross-sensitivity between strain and temperature. The system is calibrated using reference gratings with known temperature coefficients.

Users include civil engineering firms monitoring bridges and tunnels, aerospace integrators testing composite structures, and oil and gas operators tracking downhole conditions. The device is compatible with arrays from multiple vendors, provided they meet standard FBG spectral profiles. Buyers typically receive the unit with calibration certificate, USB interface, and API for integration into SCADA or LabVIEW systems. Packaging includes a ruggedized case with power supply and fiber patch cables.

Alxenses Co., Ltd. is a Hong Kong-based entity registered in Kwai Chung, with no disclosed manufacturing site or production capacity. The company does not state its founding date, employee count, or revenue. Its listing shows no certifications, client names, or quality management system claims. It is classified as an imported supplier with no verified response history.

The company appears to function as a technical distributor or system integrator for FBG interrogators, sourcing the hardware from third-party manufacturers and configuring software for end-user applications. It does not claim to design or fabricate the interrogator’s core optical components. No information is provided about firmware updates, warranty terms, or after-sales support beyond the product description.
