The maintenance free level indicators of the PF-series are suitable for level control applications with dusty, powdery, or granulated bulk material that form an angle of repose during filling. These measuring devices are the preferred choice to indicate the full-level in silos or bins that are mechanically filled for example with a screw conveyor. High reliability and safe operation even in very hard and extreme applications is guaranteed by these level limit switches. The level sensors need no power supply and therefore the installation and operation is very simple and cost-efficient.
You can get all of these quality products with ATEX approvals for use in gas and dust explosive hazardous areas. Different types of these point level sensors enable the optimal adjustment to the specific application.
