The bulk density of solids is an important process parameter in a lot of operations in which solids will be handled. The determination of the bulk density is usually a very complex operation. It is only possible by taking samples analysing these samples in the laboratory. To determine the bulk density of powder or granules during the process, Dens-M was developed.
The Dens-M sensor can be installed into the container by a flange plate (usually in a small hopper). To determine the density the sensor will be filled by the product cyclic. For this, the container has to be closed with a slide valve and to be filled until the specified filling level is reached. The sensor is now completely enclosed by the product. With an adjustable time of measurement (0 – 100 sec) the bulk density can be determined. The measurement will be shown as 4-20 mA signal. After the completion of the measurement process, the container can be emptied.
