Operating instructions
1. Description
1.1 Intended use
The level indicator observes the filling level as a limit switch in silos
and vessels. It can be used as full, demand and empty indicator for
dusty and powdery, granulated and grainy bulk goods with a max.
grain size up to 30 mm and with a bulk density of 0.3 t/m³ ... 2.5 t/m³.
1.2 Function
The bulk goods presses with its weight against the double
membrane. A tappet directly transfers the pressure from the
membranes to the switch. When the bulk goods are decreasing,
pressure is taken off the membranes and the switch will be
interconnected.
