Detailed Description
Example 1
The utility model discloses a scheme is to carry out the design of easily changing to the window piece, is surveyed the gas contamination window piece when the air chamber is inside, can change the window piece, the utility model discloses still increase to the window piece and sweep the function, prevent equipment self ageing contamination window piece, prolong the life of lens.
Window piece: the gas chamber is arranged at the periphery or inside of the gas chamber, and 100% of light emitted by the light source can conveniently penetrate through the cavity of the gas chamber while isolating the gas detected in the gas chamber from the external environment.
Light source: and a transmitting end of the optical signal.
Pollution: the attachment causes a reduction in light transmittance of the window sheet.
A spectral analysis system: and comparing the optical signals before and after the absorption of the gas to be detected, and calculating the content of the gas to be detected.
And (3) crystallization: the gas solidifies from the gaseous state to the solid state as the temperature is reduced.
The device provided by the utility model be convenient for change, and need not the screw-up, make things convenient for the scene to change, the utility model discloses a device still possesses the pollution that the function of sweeping can avoid equipment self to age and bring.
