The Principles of Measurement Level Gauges operate according to radiometric principle, utilizing the physical law that gamma radiation is attenuated as it passes through matter. This attenuation is dependent only on the type of source, the length of the absorption path and the density of the medium. Since the source type and the absorption path are constant, the measurement is affected only by the presence of the medium. Since the absorption law follows an exponential curve, the measuring effect with normal container dimensions becomes practically independent of any density changes in the product. Therefore, physical as well as all chemical properties have no influence on the measuring effect. As a consequence, the radiometric measuring method features a very high level of operational safety and requires practically no maintenance, even under difficult operating and ambient conditions.
Detector and Evaluation Technology Berthold gauges feature precise and efficient scintillation crystals to measure the gamma radiation and send a digital signal to the evaluation electronics. High crystal sensitivity allows low source activities. Automatic drift compensation, incorporated in the scintillation crystal, compensates for the effects of temperature variation and component aging.
Microprocessor-based evaluation electronics allow easy calibration and integration into your existing or planned process control system. Single-point calibration, a current loop output signal proportional to level, and automatic source decay compensation make Berthold units a trouble-free solution for your measurement task.
