SOFO Lite Reading Unit
COST EFFECTIVE FIBER OPTIC INTERROGATOR IDEAL FOR SMALL PROJECTS
Reliable and versatile fiber optic datalogger for field applications. Reads high-accuracy SOFO deformation sensors.
The SOFO Lite reading unit is able to measure up to 10 or 12 SOFO (Interferometric) sensors. SOFO sensors offer the best accuracy and temperature compensation performance for long-gauge sensing. The system is designed for static, long-term measurements and monitoring, in particular of civil structures. The SOFO Lite is integrated in a compact housing designed for installation in a cabinet or indoors. Thanks to the Ethernet interface, it is possible to address the unit remotely from a PC running the SDB software or network several SOFO Lite units to in-crease the channel count. The SOFO Lite reading unit allows to measure 10 or 12 channels. On each channel it is possible to connect a single SOFO sensor. The unit contains a processing unit that analyzes the optical signal to convert it to deformation measurements.

The main features of SOFO Lite are: cost effectiveness, accuracy and scalability, allowing the customer to profit from the best-in-class accuracy and temperature compensation of SOFO sensing technology at an unprecedented low price. This reading unit is particularly useful for smaller projects or applications where multiple reading units can be used to monitor different parts of a structure that are spread out over a large distance.
The SOFO Lite has been designed for installation indoors or outdoors with an optional protection cabinet.
