<p>Improved bulk density sampler (10) is provided for continuous sampling of material flowing in a material processing stream (16) which includes a sampling assembly including a receptacle (42) of known volume mounted on, and secured to, a load cell (46) configured to selectively measure the assembly weight both when the sampling assembly receptacle is full and empty. Preferably, the bulk density sampler includes a housing (40) for protection of the sampling assembly and receptacle from the product stream and other debris which may be present in the operating environment during the weight measurement. The bulk density sampler also preferably includes a programmable controller (160) which controls the operation of the bulk density sampler (44) and provides additional functionalities such as trend chart analysis, alarm functions, and sampling frequencies (164).</p> |
