The InlineSENS (LB 4700-5x-…) combines both a radiation source and scintillation detector in one device. Its use of low-energy gamma radiation from an Am-241 or Cm-244 source provides for strong responses to even the slightest change in product composition, with extremely low dose rates.
The isotope Am-241 or Cm-244 is used as the radiation source. The advantage: Am-241 and Cm-244 have very low radiation energies, which correspond approximately to the energy of X-rays. The density measuring system InlineSENS offers high statistical accuracy and long-term stability by using a highly sensitive scintillation detector with patented drift compensation.
The measuring system, which is made entirely of stainless steel, is permanently flanged to the pipeline and continuously measures the product density of liquids, suspensions, slurries, and bulk solids. In the case of the Am-241 version, the product pipe can also be supplied with a liner of Teflon (PTFE) or rubber if required. In the Cm-244 version, on the other hand, a polypropylene liner is installed as standard. Depending on the existing pipeline, various flange and product pipe options are available including DIN flanges, ASA flanges, and threaded connections between DN 40 and 65.
