The FSI MX optical sensing instruments are economic commercial-grade interrogators, featuring 2-16 monitoring channels. Enclosed in a field-deployable enclosure, the instrument can be operated in full-spectrum and in sensor peak detection modes.
The MX series are optimized for both static and dynamic measurements of up to 30 Fiber Bragg Gratings (FBG) based sensors per channels.
Our family of rugged MX interrogators is used extensively in civil engineering, marine, railways, roads, energy, geotechnical, industrial, security, medical, and many other commercial applications. This economy model is specifically useful for security, civil engineering, energy, process control, material qualification labs, and R&D programs. The industrial-grade design scales well for volume production.
