In practical applications, the diameter of the sampling tube 11 is usually 1/2 to 1/4 of the diameter of the material conveying pipeline, such as 1/2, 1/3, 1/4 or other values between 1/2 and 1/4. When the diameter of the sampling tube 11 is beyond this range, the diameter may be too large or too small, which may cause the sample to be ejected during sampling. For example, the sampling tube 11 has a diameter of 50mm, while the material conveying pipe has a diameter of 159 mm.
It should be noted that the wall of the sampling tube 11 includes a material outlet, and after the particulate matter enters the tube of the sampling tube 11 from the nozzle of the first end of the sampling tube 11, the particulate matter can flow out through the material outlet.
