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 and empty indicator for dusty
and powdery, granulated and grainy bulk goods with a max. grain
size up to 100 mm and with a bulk density of 0.3 t/m³ ... 3.0 t/m³.
1.2 Function
Bulk goods, being dumped besides the pendulum, are moving the
pendulum more and more aside, as the filling level increases.
A signal switch registers this movement and evaluates it.
