Safe for critical processes
The high reliability of the measurement is supported by important diagnostic functions, such as permanent monitoring of the detector function by crosschecking the
The cosmic radiation control also makes it possible to keep the required source activity very low. Only Berthold is able to use the LB 480 as a density or min/max level switch in SIL 2/3 safety circuits, in addition to its use as a level field device.
SIL certified option
The SENSseries LB 480 detectors are certified for use in SIL2 applications. Even SIL3 is achieved with homogenous redundancy. The certificate covers all measurement applications, from high level or low level alarms to continuous level measurement and density measurement. Thus safe operation of critical processes is guaranteed.
X-ray Interference Protection (XIP)
With this function, weld tests can no longer distort the measured value. The measured value is frozen until the external radiation influence is over. A digital output signals the detection of interfering radiation. All our level measurements are equipped with XIP.
Product Radiation Compensation (PRC)
Does your product contain natural radioactive radiation? No problem! The Product Radiation Compensation (PRC) feature provides reliable, accurate level measurement through independent activity measurement and integral compensation for a reliable and precise level measurement.
Gas Property Compensation (GPC)
In the case of radiometric measurement, gas density variations can falsify the measured value, unless you have gas density compensation from Berthold. With the feature GPC, a second measurement determines the current gas density in the tank and has a compensating effect on the connected level measurement.
Do you need a measurement with an extremely short reaction time?
The LB 480 SpeedStar can be used where reaction times in the millisecond range are required. While standard measurements calculate a new measured value every 500 ms, the Speedstar version with a measuring time of 50 ms is 10 times faster. This allows very fast object recognition, e.g. detecting the beginning of a steel plate being moved at a relatively high speed on the roll conveyor, or measuring a density profile on pipes or plates detected directly during extrusion. The level of gas bottles can also be measured while the bottles are still being transported.
