MEASURING ASSEMBLY FOR THE RADIOMETRIC DENSITY OR FILLING LEVEL MEASUREMENT OF A MEDIUM IN AN EXPLOSIVE REGION

摘要

The invention relates to a measuring assembly for radiometric measurements in an explosive region. The photo-sensitive unit (5) of the detector (4) is configured in such a way that it is surrounded by an encapsulation (6). In this way, the encapsulation (6) both serves as explosion protection and is designed in such a way that it causes the conversion of the incident radioactive radiation into electromagnetic radiation. This is achieved in that the encapsulation (6) is formed by scintillating material at least in one region (7). This results in the advantage that, despite the explosion-safe encapsulation (6), the sensitivity of the photo-sensitive unit (5) is not reduced, rather it is increased. The in turn increased the potential measurement accuracy of the entire measuring assembly.
