I-MON E Interrogation Monitors
Document Actions
The I-MON Series E-USB Interrogation Monitors offer real-time spectrum monitoring of FBG sensors. High spectrometer resolution combined with broad wavelength range provides high-resolution interrogation monitors allowing measurement of a large number of FBG sensors. High sensitivity allows high resolution also at very low light levels.
With its USB interface and data acquisition software it provides easy setup with a laptop, and can act as stand-alone monitor in combination with a customer-selected light source. Additionally, the I-MON Series E-USB offers straightforward integration with the customers interrogation system control PCB and external trig input enable exact timing.
Applications
Stand-alone Integration Monitor and/or OEM Interrogation Monitor Modules:
- Temperature measurements
- Pressure monitoring
- Strain measurements
- Vibration analysis
- Low light-level measurements

(*) At input power levels of –60 dBm and –70 dBm resolution less than 0.5 pm can also be achived by increasing the integration time.
(**) Note that by applying temperature control or temperature correction the wavelength accuracy over the entire wavelength range can be improved to 10 pm.
