Home page EARTHING SYSTEM EARTHING SYSTEM EARTHING CONTROL SYSTEM Control and discharge system for electrostatic charges suitable for road tankers, rail tankers and any movable tanker for dangerous items, ready for one/two double circuit clamps PTA ISEO-2. System is complete with arrest/consensus optical warning and changeover contact free from output voltage. The need to transfer from one place to another dangerous flammable fuels and liquids as gasoline and diesel highlighted the serious risk due to uncontrolled discharge of static charges cumulated on movable tanker-units during transfers following the well known natural phenomena when connected to loading / downloading tools (fixed). Following the natural tendency to the equilibrium of electrical potential a loading harm of a fuel depot, being connected to general earth circuit, will act as a discharge preferential path of all static charges cumulated on a next road tanker to load for instance gasoline. EARTHING CLAMP Reliable, robust, handy and easy to use, PTA Series clamps are the ideal tool for tanker loading platform equipped with electronic devices to signal correct grounding. They can be easily connected to any grip, even rusty ones. They are made of aluminium and the electrical continuity is ensured by the carbonitrided steel contact tips which make a firm connection to any foothold having a thickness between 2 and 20 mm.
