ABSTRACT:
A level meter, employing the radar principle for measuring the fill level of a medium in a container, includes a signal transmitter serving to transmit an electromagnetic signal, an electric conductor system for conducting the electromagnetic signal into the container and returning reflected components of the electromagnetic signal from the container, and a signal receiver serving to receive the reflected components of the electromagnetic signal. An electric conductor system is provided at its upper end with a suspension by which it is attached to a device on the container. A tensile-load testing device is placed between the suspension and at least a part of the electric conductor system, featuring a break point for the electromagnetic signal, with the distance between the break point and the signal transmitter or the signal receiver varying as a function of the tensile load bearing on the conductor system. This permits easy monitoring of the tensile forces to which the conductor system and the suspension are exposed, so that any damage to these devices as a result of excessive loads can be prevented.
