Radiation Interference Discrimination (RID)

If you want to continue to measure with impending external radiation, then the LB 470 series with RID option is required. The measurement continues without interruption, even if external radiation is present.

Cosmic radiation

The earth is continuously exposed to high energy radiation originating from outside the solar system – a discovery that was honored with the Nobel Prize in 1936.

Long-term stability of a detector

The long-term stability of a detector is extremely important for a consistently high quality measurement performance and accuracy during the entire operation.

Detector sensitivity

The detectors sensitivity describes how efficiently radiation is converted into a useable signal (i. e.”counts”).

Option SIL2 / SIL3 pour la sécurité des procédés

Pour maintenir la stabilité de la mesure et surveiller la fonctionnalité du détecteur, le "contrôle de gain du rayonnement cosmique" de Berthold, unique et inégalé, est utilisé.

SIL2 / SIL3 option for safety critical processes

To maintain the measurement stability and to monitor the detector functionality, the unique and unrivaled Berthold "cosmic radiation gain control" is used. This allows the use as a SIL2 high, or even low point level switch, without additional measures.

Radiometric Measurement

Radiometric measurements for industrial processes have been around for several decades. They are an important component in the successful performance of critical level, density and flow measurements.

Frequently Asked Questions (FAQ)

Yes! The detectors SENSseries LB 480 from Berthold have been awarded SIL2 / SIL3 certification. This certificate covers the measurement applications level switch, continuous level and density.

Yes, but this can be easily compensated for with Berthold's Gas Property Compensation (GPC).

No! Berthold detectors have features (XIP or RID) that handle interfering radiation and thus maintain a stable and reliable measurement.

A radiometric measurement is based on the absorption of radiation when it passes through matter. Radiometry means "measuring with radiation".

Extreme measurement conditions often cause conventional measurement technology to fail, and it is precisely in such situations that radiometry is the measurement technology solution. Berthold offers a variety of detectors to fit the needs for your application with industry leading detector sensitivity, temperature stability, and aging stability, as well as custom engineered solutions and rod sources.

Berthold measurement systems stand for the highest precision, quality and reliability. With our specialized knowledge and extensive experience, we develop solutions with our customers for new, individual measurement tasks.

 

Yes of course! With the aid of the PRC (Product Radiation Compensation) feature, our gauges can compensate and correct for the additional radiation coming from your process.

No! With doserates comparable to typical radiation exposures in airplanes, and falling below the NRC mandated maximum doserates, with reasonable precautions being near a radiometric gauge {for a short period of time} is safe.

As good as never! With our industry leading temperature and aging stability, Berthold’s radiometric gauges do not need to be recalibrated during normal operation.

You must have a license from you governing body to own and use the nuclear source, and perform regulatory required shutter checks at minimum every six months and leak tests at minimum every three years, depending on the device.
