5 Installation Shields for Flange Mounting IMPORTANT For some specific applications, it is important to identify any damage to the dip pipe in order to secure the radioactive source before it is damaged. Fig. 8 and Fig. 9 show installation proposals which meet the most stringent safety requirements.
Page 27
Note the project-specific requirements and all informations in chapter 1 Technical Data and chapter 2 Mounting Layouts in the document "Technical Information" (see appendix). Various versions of flange adapters are available from Berthold. NOTICE The shield as well as the sources must not be subjected to process pressure! Fig.
5 Installation Shields for Flange Mounting Marking The warning sign (Fig. 11, item 1) indicates the beginning of the control area as long as the control area is outside the shield. If the control area is within the shield, then the radiation warning sign (Fig. 11, item 2) already applied to the shield is sufficient.
Shields for Flange Mounting 6 Usage Usage The shield may only operate by competent persons (see 2.3 Qualification of the Personnel). When operating the shield, unexpected changes at the process control system can occur. Before moving the sources or removing the sources from the measuring position, the guidelines of the system operator must be observed.
6 Usage Shields for Flange Mounting Commissioning Moving the Source into its Measurement Position Depending on the respective measurement arrangement, either a steel rope or a flexible shaft is included in the scope of delivery of each source. By means of the steel rope or the flexible shaft, the radioactive source can be moved into its measurement position within the dip pipe in the vessel.
