Product specification
Evaluation unit for non-contact density measurement
Description
The heart of the DECON 21 is a microprocessor-controlled small computer for calculating the density or concentration or solids content of liquids, suspensions and bulk materials directly on pipes or container walls, which in combination with a radiation source and a detector forms a complete measuring section.
By determining the absorption of radioactive radiation as it passes through a substance, its density and various measurement variables derived from it, such as solids content, acid strength or concentration, can be measured without contact.
Since the radiometric density measurement is independent of the physical state of the substance (solid / liquid, hot / cold, etc.), it can be used successfully with almost all bulk goods, liquids and solutions / dispersions / emulsions.
Because the radiation can also penetrate steel walls, measurements can be carried out directly on pipes and containers.
The measuring section consists of a radioactive source, the radiation of which emerges from a shielding container as a thin measuring beam, a scintillation detector DDxx, which registers the attenuated radiation after crossing the substance to be measured, and the evaluation unit DECON 21, which processes this information.
