产品摘要详细参数产品图片
The I-MON 256/512 USB interrogation monitors offer real-time spectrum monitoring of FBG sensors. The USB series is based on the I-MON 256/512 OEM series. Adding our new USB interface makes it possible to acquire spectra with up to 6 kHz, while maintaining sub-picometer wavelength fit resolution.
Data acquisition software provides easy setup with a laptop, and the I–MON can act as a stand-alone monitor in combination with a customer-selected light source.
Applications
Stand-alone Interrogation Monitor and/or OEM Interrogation Monitor Modules:
- Temperature measurements
- Pressure monitoring
- Strain measurements
- Vibration analysis
