The KOBOLD PLS monitors the maximum fill level of bulk solids in storage tanks and silos. The monitor consists of two parts: the aluminum connection housing with the microswitch and the connection terminals and the pendulum rod with the measuring cone. The PLS is installed vertically on the side of the filling piece.
When a silo is filled with bulk solids, the rising level causes the measuring cone of the level monitor to swing to the side. This movement is directly transferred from the pendulum rod to the microswitch. For more details and specs, checkout the PLS datasheet and PLS user manual.
