Minimization of extraneous influences

Due to the measuring principle of radiometry, radiometric measurements can be influenced by various external influences.. These include, for example, interfering radiation, radioactive media  or fluctuating gas densities.

In industrial plants, non-destructive tests are regularly carried out using gamma radiation. However, radiometric level measurements can be influenced by exactly this radiation, which leads to a significant increase in the count rate and thus to a misinterpretation of the level. Falsification of the measured value by external radiation can be prevented by Berthold’s XIP (X-ray Interference Protection) function. In this case, the measured value is frozen when interference radiation is detected. This is signaled accordingly via a digital output. If freezing the measured value is not wanted, Berthold also offers systems with RID (Radiation Interference Discrimination). Due to the energetic differentiation between the external radiation and the radiation used in the measurement, the level measurement can continue without interruption.

If the product to be measured contains natural radioactivity (NORM products), a special measurement solution is required. Thanks to the PRC (Product Radiation Compensation) function, a Berthold level measurement can also be carried out on radioactive products without any problems by compensating the measurement accordingly.

Likewise, fluctuating gas densities can falsify the measured value unless a gas density compensation GPC (Gas Property Compensation) from Berthold is used.
