LB 440 is used for the contactless, continuous measurement of liquids and bulk materials in reactors, vessels and bunkers.
The document describes the Berthold LB 440, an evaluation unit designed for industrial radiometric measuring arrangements. It details how the system utilizes a source and detector to measure product levels within containers, supporting various configurations such as rod-to-point or point-to-rod geometries.
Key features of the LB 440 include operation via membrane keys with multilingual softkey guidance, continuous self-monitoring of electronics, and data protection using FLASH memory without battery backup. The unit interfaces with sources like Cobalt-60 or Cesium-137 and detectors such as scintillation counters (Nal crystal) to ensure high sensitivity and interference immunity via FSK-modulation.
Scintillation counters are used, which consist of a Nal crystal for rod detectors or a plastic scintillator for point detectors.
