APPARATUS FOR TAKING GAS SAMPLES FROM BULK MATERIAL IN A CONTAINER

摘要

of the invention Apparatus for taking gas samples from bulk material in a container In an apparatus for taking gas samples from a bulk material container having a cell wheel-type discharge control valve and a sensor for taking the gas samples, the sensor is disposed in a chamber outside the control valve and communicates with the cells of the cell wheel valve by way of an opening in the wall of the control valve housing. The sensor is arranged within the chamber in such a way that the sensor itself does not come into contact with the bulk material, the gas components in which are to be measured. A deflector plate passes bulk material that enters the chamber, back into the cell wheel control valve. The sensor is in the form of a filter hose and is provided with a shaker means for freeing it of dust that clings thereto.
