ZZ-FBG series fiber optic grating demodulator (modular)
1、Summary
Nanjing Zhunzhi Sensing Technology Co., Ltd. is a technology innovation company composed of multiple R&D personnel (4 PhDs, 100% bachelor's degree or above), technical personnel, and marketing personnel who have been engaged in the field of fiber optic sensing for more than ten years. At the same time, it relies on the Precision Photon Integrated System and Application Engineering Research Center of the Ministry of Education of Nanjing University in the field of optical device integrated chip technology, integrating research and development, production, sales, and service, and focusing on the new generation of fiber optic sensing。
The ZZ-FBG series fiber optic grating demodulator is a high-precision and high-resolution device developed by our company. It can provide a stable scanning light source for fiber optic grating sensor arrays and analyze their output optical signals, and serve as a high-precision spectrometer. This product integrates computer, fiber optic communication, fiber optic sensing, fiber optic transmission, optoelectronic control and other technologies, and is the latest application result of fiber optic grating sensing technology. This product is equipped with a standard computer network interface, allowing users to collect, store, and analyze data through the computer。
The host supports the conversion of wavelength to physical quantities, supports the calculation of all sensor structures, supports first-order fitting, polynomial fitting, reference temperature method temperature compensation, cantilever beam method temperature compensation, etc., and meets the operation requirements of all manufacturers of sensors in the 1522-1570nm wavelength range on the market。
According to the differences in data processing within the instrument, the ZZ-FBG series offers a total of 6 versions based on application scenarios and software functions, covering module type, chassis type, and wireless communication type (with built-in DTU), which can meet the needs of various application fields。2、Performance Index
