ABSTRACT:
A detector for breaks in screens and filters employed in material separators includes a transmitter of RF signals and a receiver of RF signals located to either side of a screen. The separator includes a chamber having a barrier to RF signals with a path through the barrier being defined through the screen mount. The screen mount receives a screen to extend fully across the path.
