FBG Interrogator

IDP4151-FBG Interrogator

Description
IDP4151 FBG interrogator is a highly accurate and quickly measuring instrument with multi-channel of multi-sensor. It provides the complete and reliable resolution to FBG Sensor Measurement System. It is easy to directly monitor the wavelength or other physical parameter continuously. It utilizes so advanced dummy instrument technology that the software application can be modified according to the actual requirement. It widely applies to monitoring temperature, strain in special environment like power system, construction field and oil field.
Applications
• Continuous lifetime health monitoring of bridges, dams, buildings, tunnels, ships, aircraft, trains, and other complex structures.
• Measurements of fiber Bragg grating (FBG) strain gages, temperature probes, accelerometers, pressure, displacement, and other FBG sensors.
• Simultaneous static and dynamic measurements.
Features
• Built-in wavelength module
• Spectral Diagnostic View for optimizing sensor system setup and operation.
• High stability and reliability.
• Customized Labview Program.
