National Instruments Introduces Fiber Optic Sensor Interrogator for PXI Express
AUSTIN, Texas –National Instruments announced the NI PXIe-4844 optical sensor interrogator, a two-slot 3U PXI Express module for fiber Bragg grating (FBG) sensors. FBG sensors operate by reflecting a wavelength of light that corresponds to changes in physical phenomena such as strain and temperature. Unlike conventional electrical sensors, FBG sensors are nonconductive, electrically passive and immune to electromagnetic interference, making them a safe and reliable alternative in environments subject to noise, corrosion or extreme weather. The transmission medium is standard optical fiber instead of copper wire, making it possible to take measurements over long distances of up to 10 km. Several sensors can be daisy chained along a single optical fiber to greatly reduce the size, weight and complexity of the measurement system.
The NI PXIe-4844 optical sensor interrogator is part of the NI SC Express family of sensor measurement modules for PXI Express. It features four optical channels that are simultaneously scanned at 10 Hz. Each channel has an 80 nm wavelength range (1510 to 1590 nm), which can scan 20 or more FBG sensors per channel (more than 80 FBG sensors per module, depending on the sensor range). For high-channel-count applications, engineers can further extend the maximum number of FBG sensors per module by using an external optical multiplexer or by adding more NI PXIe-4844 modules in the same PXI chassis.
Engineers and scientists can program the NI PXIe-4844 with easy-to-use configuration and driver software to shorten setup and configuration time. The module includes the NI-OSI Explorer utility for automatic sensor detection and simplified sensor configuration as well as the NI-OSI driver software with easy-to-use LabVIEW API for acquiring measurements in scaled physical units. Using NI LabVIEW software, engineers and scientists can view, log and analyze the sensor data, and extend applications to include synchronization with other sensor types, instruments or control systems.
The industry-standard PXI platform for measurement and automation provides the industry’s highest-performance timing and synchronization capabilities and the high-throughput PCI Express bus. The NI PXIe-4844 can be integrated into the same chassis as other PXI modules including SC Express for complementary electrical data acquisition and control. With the PXI platform, engineers and scientists can combine both optical and electrical measurements into one PXI chassis.
