Multi-point measurement capable FBG sensor

Due to the ability to detect minute structural changes in the processed area caused by external forces and temperature as wavelength shifts, it is possible to measure the temperature and strain at multiple points with a single sensor. 【Features】 - 20 sensors arranged on a single fiber (customizable to freely arrange up to 30 sensors) - Compact and lightweight interrogator (X100: 60g) - Uses light, so it is not affected by electromagnetic radiation - Capable of high-speed sensing - Customizable length of FBG sensor chain and measurement points - High wavelength accuracy (< 0.15nm) - Highly durable

For temperature monitoring of transformers, reliable temperature monitoring is possible without being affected by noise from EMI/RFI and high voltage environments.
