The FieldSens-W is a compact and robust multi-channel signal conditioner to be used with any of Opsens Solutions’ interferometric fiber optic sensors, i.e. the WLPI fiber optic sensors, for temperature, pressure, strain, and position measurements.
At the heart of the FieldSens-W is the Opsens Solutions’ White Light Polarization Interferometry (WLPI) technology (patent # 7,259,862) which provides a mean for making accurate and absolute measurements of the path length difference of any type of interferometric fiber optic sensors, whose difference varies according to the measure and of interest. The FieldSens-W is the latest generation of Opsens Solutions’ signal conditioners equipped with state-of-the-art technologies. Highly versatile, it supports a broad range of fiber optic sensors and offers measurement sampling rate up to 250 Hz (when 1 channel is enabled). Maximum number of modules is 32 with up to 12 channels per module. You can stack modules based on the number of sensors to be monitored (up to a maximum of 384 channels).
The unit offers multiple interfaces for remote control and real-time data acquisition: EtherCAT®, 10/100 Base-T Ethernet, USB, RS-232 and CAN FD. Open interface for easy integration with existing external data acquisition software. An optional portable touchscreen display is also available for stand-alone configurations (useful for on-site maintenance or remote locations). The unit is equipped with internal storage to provide the necessary autonomy in remote locations, years of recording at low acquisition rates.
