Further application possibilities are also the use as X-ray alarm or real
value correction.
If X-ray alarm is selected, the instrument detects radiation from exter-
nal sources. Possible external radiation sources can be, for example,
aweldjointtestinaneighbouringfacilityorotherradiometricinstru-
ments.
When the instrument operates as real value correction it transmits the
real value to correct another radiometric sensor. The measurement
can thus be adapted perfectly to the situation in the vessel.
In radiometric measurement, a Caesium-137 or Cobalt-60 isotope
emitsfocussedgammaraysthatareattenuatedwhenpenetrating
thetubewallandthemedium.TheNaIdetectorontheoppositeside,
on a pipeline for example, receives the radiation. The intensity of the
radiation is dependent on the density of the measured media. The
measuring principle has proven to be very reliable in conjunction
withextremeprocessconditionsbecauseitmeasurescontactlessly
fromoutsidethroughthetubewall.Themeasuringsystemensures
maximum safety, reliability and plant availability independent of the
medium and its properties.
