  • Page 9: Principle Of Operation

    When the intensity of the radiation drops below a defined value, e.g. due to damping, then the POINTRAC 31 switches. The measuring principle has proven itself well under extreme conditions because it measures contactlessly from outside through the vessel wall. The measuring system ensures maximum safety, reliability and plant availability independent of the medium and its properties.
