Level Switch - Mini-Switch LB 471

Application. The BERTHOLD level switch is used in all branches of industry, including the food industry. This measurement system is applicable where one or more alarm levels of liquids or bulk solids have to be monitored. In fact, the BERTHOLD level switch is suitable for installation on all types of vessels or bunkers like storage tanks, hot-storage bunkers, vessels with agitators, high-pressure reactors, cyclones or feeder chutes.

The Function. The operation of the measuring system is based on the application of the radiometric measuring principle, i.e. the physical law of absorption of gamma radiation as it passes through matter. This measuring principle has been proved successful on the most difficult applications for many years now.

An arrangement of a level alarm switch is shown in picture 1. The shielded radiation source is installed outside the vessel at the height at which the alarm must be indicated. The radiation detector , is mounted at the same height on the opposite side of the vessel. The detector signal is transmitted via a two-core standard cable to the evaluation unit 3 .

Interface measurement in desalters

Interface measurements in desalters are often regarded as not being very critical, even though every drop of oil, to be refined, passes through the desalter. As refineries try to maximize their margins, so-called opportunity crudes are often used. These crude oils generally contain increased levels of ...
