Radioactive Level Switch

Radioactive Level Switch

Our radiometric level switches are used in a wide variety of industries, providing either a high or low level alarm. The measurement is carried out non-contacting and non-intrusive.

All components of the measurement system are mounted on the outer wall of the vessel, without any contact with the measured material. They can be installed on all types of vessels or bunkers like hot storage tanks, vessels with agitators, high-pressure reactors, cyclones or feeder chutes.

The Berthold Mini-Switch LB 471 is a straightforward and dependable solution for point level measurement applications in industrial settings.

X-ray Interference Protection (XIP)
With this function, weld tests no longer cause sudden fluctuations in the measured value. When weld tests are detected, the measured value is frozen until the external radiation event ends.

Function:
Provides high-level or low-level alarms for liquids or bulk solids.
Ideal for applications requiring a simple on/off indication of whether a material has reached a specific level in a tank or vessel.

Technology:
Employs proven 2-wire technology for ease of installation and operation.
Requires minimal wiring, reducing setup complexity.

Design:
Separate transmitter unit simplifies calibration and operation.
Calibration adjustments and status monitoring can be performed conveniently without directly interacting with the sensor.
Local display on the transmitter provides clear level switch output visualization.

Overall, the Berthold Mini-Switch LB 471 is a user-friendly and cost-effective solution for basic point level measurement tasks. Its simple design, 2-wire technology, and separate transmitter for easy calibration make it a suitable choice for various industrial applications.

Berthold SENSseries LB 480 LS

The SENSseries LB 480 can be easily installed as a radiometric level switch on vessels and chemical reactors, even where other measurement systems reach their limits due to vessel geometry or measurement conditions. Our level switch measurement is used in all demanding industries. Wherever one or more limit levels of liquids or bulk solids are monitored, our contactless level measurement can be used, even with very thick-walled or large containers.

SENSseries LB 480 level measurement is particularly suited for demanding measuring tasks in safety-related applications. This line offers detectors certified for use in SIL 2 systems. Berthold is the first manufacturer of SIL certified radiometric level, level switch (min./max. alarm) and density measurement systems. SIL 3 can be achieved with the redundant installation of two LB 480 SIL 2 systems.

High reliability is supported by important diagnostic functions, such as permanent monitoring of the detector functionality by crosschecking the cosmic background radiation and much more. This guarantees outstanding operational safety.

Cosmic radiation control also makes it possible to keep the required source activity very low.

Berthold's LB480 SIL model is unique in the radiometric gauge market for being certified for density and low level switch measurements, in addition to high level switch and continuous level measurements.
