Abstract

Dispozitivbul, conform inventiei, se refera la protectia detectorului de raze gamma cuprins într-o instalatie pentru masurat grosimea tevilor împotriva radiatiilor termice. Dispozitivul rezolva problema prin aceea ca, suportul instalatiei de masurat care cuprinde detectorul de raze gamma, este executat cu o cavitate prin care circula apa cu o presiune detrminata, un filtru silicatic protejeaza detectorul de raze gamma împotriva radiatiei termice, iar obiectul supus masurarii este înconjurat de o manta cu pereti dubli de tipul unui transportor cu role, strabatuta de apa la o presiune determinata.The device according to the invention relates to the protection of the gamma ray detector contained in a device for measuring the thickness of the pipes against thermal radiation. The device solves the problem in that the support of the measuring device comprising the gamma ray detector is made with a cavity through which the water circulates with a deformed pressure, a silicate filter protects the gamma ray detector against thermal radiation and the subject to be measured is surrounded of a double-skinned jacket of the type of a roller conveyor crossed by water at a determined pressure.
