The FAZT I4-16W optical sensing instrument combines the core technology of the company’s lower-cost workhorse model FAZT I4W interrogator together with four 1×4 high-reliability, high-speed, premium performance solid-state optical switches to create a 16 Channels workhorse interrogator. Enclosed in a field deployable stainless-steel casing, the instrument provides peak detection for up to 30 Fiber Bragg Gratings (FBG) based sensors on each of its 16 channels. The instrument can be operated in full spectrum and sensor peak detection modes and is optimized for both static and dynamic measurements.
Our family of rugged FAZ Technology interrogators is used extensively in marine, railways, roads, energy, civil, geotechnical, industrial, security, medical, and many other commercial applications. It is also the instrument of choice for Research and Development Centers that seek to achieve ultimate precision and repeatability measurements. The industrial grade design scales well in volume production.
High resolution, precision and accuracy: The FAZT I4-16W Interrogator returns measurements in 1pm steps across its wavelength range. Using patented FAZ Technology scan-by-scan calibration to its internal Gas Cell, the instrument features 0.5pm absolute precision and absolute accuracy of 3pm.
Top reliability: The FAZT I4-16W Interrogator is based on a semiconductor tunable laser that has no movable parts, no tunable filters, and no opto-mechanical switches, which delivers top reliability over a broad temperature range to form 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 instrument’s performance parameters to fit many different sensor configurations. Designed to monitor many types of sensors from narrow bandwidth (100pm) FBGs used in highsensitivity accelerometers, pressure sensors, hydrophones, and microphones, to wide bandwidth (1.5nm) FBGs used in bio-sensing. Hardware implementation of peak tracking algorithms for FBG sensors including programmable gain per sensor, width/height thresholds, and distance to sensor setting for accuracy at long distance. The laser output power is -1 dBm to -3 dBm and performance is maintained even with 20dB optical power loss on each sensors channel.
Systems and network ready: High speed data acquisition and on-board computer processing make the FAZT I4-16W easy to use and easy to transmit large volumes of data by network connection. Trigger Input support enabling synchronization of multiple optical and electrical sensor systems. The Ethernet port for high speed data transfer is 100Mbit/s, with all interrogator settings programmable over a REST interface. NTP (<10ms timestamps) Time accuracy with optional GPS time (<10µs timestamps).
Low Cost and High Quality: The FAZT I4-16W Interrogator is based on the company’s flagship ultimate performance FAZT I4G Interrogator and it has been optimized to address applications demanding a lower cost higher channel unit while maintaining the quality and reliability of a premium grade instrument.
