MOLOSroto DF28 – Limit switch with protection tube

MOLOSroto DF28 for a wide range of applications

Thanks to its protective tube, the MOLOSroto DF28 is particularly impressive as a full indicator in silos and containers with heavy bulk solids. Special configuration options allow this level indicator to be used up to 500 °C, for level monitoring even in the filling flow or as a level indicator with manual height adjustment.
