  • Product Details

The fiber optic grating sensing analyzer is suitable for signal demodulation and sensing data acquisition of various types of fiber optic grating sensors, such as temperature, strain, pressure, displacement, etc.
The fiber optic grating sensing analyzer adopts high-power laser light source and high-speed multi-channel parallel light detection technology. Compared with traditional ASE light source technology, the output light power of the light source is over 85%, the output power of the light source is increased by more than 100 times, and the power consumption is reduced by 50%. The effective service life of the light source is increased by more than 10 years, which can accurately detect weak fiber optic grating sensing signals caused by fiber optic transmission line losses or cascaded losses of optical splitters in engineering sites.

The fiber optic grating sensing analyzer has 1-32 synchronous measurement channels, and the synchronous scanning frequency can be set between 1-350Hz. The acquisition time of each measurement channel is strictly synchronized, and each channel can be connected to 1-20 sensors. It is equipped with an online calibration wavelength reference module, which does not require calibration after leaving the factory. It can ensure a measurement accuracy of ± 3pm within the working temperature range.

The fiber optic grating sensing analyzer is an integrated analyzer with a built-in low-power embedded processor, which is stable and reliable in performance, and meets the needs of long-term online monitoring in the industrial measurement field and mobile measurement in field construction sites. The entire chassis size is standard 2U, including the following interfaces:

10M/100M Ethernet interface: 1
RS232 or RS485 interfaces: 2
VGA display interface: 1
USB interface: 2
PS/2 keyboard and mouse interface: 1
Sound and light alarm: 1 unit
Relay output interface: 4 channels
