PORTABLE PROBE FOR EXTRACTING POWDER SAMPLES DRAGGED BY GASES AT HIGH TEMPERATURES.

摘要

The present invention refers to a portable probe for extracting powder samples from the inner portion of ducts and cyclones where said powders are moved by gas at high speed and temperature, maintaining said samples in a confined environment and without pollution with the purpose of carrying out a sampling and process control that ensure the quality of the corresponding products. Taking the cement and grain drying industries as example and those industries handling small particles moved by gases at high speed and temperature, it is of substantial importance to take samples in the different steps of the manufacturing process, where it is required to collect the samples and maintain them in a specific atmosphere for avoiding pollution thereof.
