Key Features

Repeatability, accuracy, and dynamic range: The M2 Interrogator provides measurements across its wavelength scanning range of 40nm. Using USA patented laser calibration technology, the instrument features +/- 2pm repeatability, +/-10pm accuracy, and 25dB dynamic range with automatic gain and threshold control adjustments. Manual settings option for thresholds and gain stages also included.    

Top reliability: The M2 Interrogator is based on a semiconductor tunable laser that has been deployed in large volumes in various field applications and features the worlds lowest MTBF. The interrogator has no movable parts, no tunable filters, and no optical switches, which enables top reliability over the standard temperature range of -15C to +55C. The M2 is also available upon request with -40C to +85C rating. The M2 is suitable for use as an integral part of a very rugged and reliable sensing system.

Adaptive to more types of sensors: The integrated electronics and embedded software allow the user to quickly adapt the instruments performance parameters to fit many different sensor configurations. Designed to monitor many types of sensors from narrow bandwidth (100pm) FBGs used in accelerometers and pressure sensors, to wide bandwidth (3.0nm) FBGs used in bio-sensing. Hardware implementation of peak tracking algorithms for FBG sensors included. The laser output power is <7 dBm (5mW). Performance is maintained even with 20dB optical power loss on both of the M2s channels.

Systems and network-ready: High-speed data acquisition and on-board computer processing make the M2 easy to use and easy to transmit large volumes of data by network connection. The Ethernet port for high-speed data transfer is 100Mbit/s. Separate serial UART port available to change the M2 IP address.

Lowest Cost and High Quality: The M2 is based on the companys solid-state instruments platform and it has been optimized to address applications demanding the lowest cost while maintaining the quality and reliability of a high-quality instrument. Also available in 1, 4, 8, 16, 24, and 32 channel configurations.

 

Description

The M2 optical sensing instrument is an economic commercial-grade interrogator, featuring 2 monitoring channels. Enclosed in a field-deployable enclosure, the instrument can be operated in full-spectrum and in sensor peak detection modes. The M2 is optimized for both static and dynamic measurements of up to 30 Fiber Bragg Gratings (FBG) based sensors on both of its 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.

 

FSI M2

Note 1: FBGs from 100pm to 3.0nm BW@3dB (FWHM) are supported. Best performance results obtained using 250pm FBGs.

Note 2: Dynamic gain per channel (6 levels covering 25dB of gain) delivering >25dB optical power dynamic range (saturation – minimum detectable power levels) at 1kHz rate.

Applications in Security, Civil Engineering, Industrial, Material Qualification Labs, and Research Centers
