The KOBOLD pendulum level monitors model PLS serve for the monitoring of the maximum fi ll level of bulk solids in storage tanks and silos. The monitor is made out of two parts: the aluminium connection housing with the microswitch and the connection terminals and the pendulum rod with the measuring cone.

The monitor is installed vertically on the side of the filling piece. When a silo is fi lled with bulk solids, a cone is created which causes the measuring cone of the level monitor to swing to the side as the fi ll level increases. This swing movement is transferred from the pendulum rod to the microswitch directly. The instruments are also available with an ATEX certifi cate (1/2 D Zone 20/21/22) for use in areas where there is a risk of dust explosions.
