SOFO VII MuST FBG Portable Reading Unit

New

PORTABLE FIBER OPTIC INTERROGATOR READS BOTH SOFO AND FBG SENSORS

Reliable and versatile fiber optic datalogger for field applications.
Robust and portable enclosure and integrated PC, touch screen and battery.

Description

The SOFO VII/MuST Portable Reading Unit is a universal reading unit able to measure both SOFO (Interferometric) and MuST (Fiber Bragg Grating) sensors. The Portable measurement units employ proven con-tinuous swept laser scanning technology. They include a NIST traceable wavelength reference that provides continuous calibration to ensure system accuracy over long term operation. The high dynamic range and output power allow high resolution to be attained even for long fiber leads and lossy connections. The SOFO VII MuST Portable Reading Unit allows measuring 4 channels. On each channel it is possible to connect up to 5 SOFO sensors (external 1×5 splitter needed) and from 7 to 25 MuST FBG sensors (depending on sensor type, see sensor datasheets for details). The unit contains a PC that provides data logging and remote interfacing functionalities. The main features are:

Robustness & portability: 24/7 operation ensured by clever design, careful selection of components (electronic, optical, mechanical), compact assembling and rugged carrying case optimized for field use.

High interrogation capacity: broadband tuning range and 4 parallel optical channels allowing the simultaneous measurement of a large number of sensors.

Options: SOFO sensor 1×5 splitters
