Sy-bx-200 portable gas analyzer technical scheme
Sy-bx-200 portable gas analyzer is designed based on the principles of infrared, ultraviolet absorption, TDLAS, electrochemistry, PID, etc. Portable use of advanced correlation filtering technology (GFC) at home and abroad. Multiple infrared and electrochemical sensors are built in the instrument. The signal spectrum of cross analysis is used as reference signal, and the signal of gas to be measured is used as reference signal. The signal is subtracted by digital circuit to get the signal change of measured gas. At this time, the change of signal depth is the gas concentration value. The signal is converted into voltage signal, amplified by gain, and passed through microcomputer 10 Segment linearization data, and finally display the gas preparation concentration through the display screen.
