Protection Against Lightning
Weighbridges are vulnerable to damage by lightning strikes, the consequences of which can be very expensive to repair, not to mention the knock-on effects of the weighbridge being out of order.
There are various types of lightning strike, but the one that concerns us is the dramatic forked lightning. A weighbridge, by nature, is very unlikely to be the tallest structure in its locality and so will rarely be directly struck by lightning. If it does receive a direct hit then no weighbridge in the world could withstand the electrical energy that would strike it and then pass through its load cells as the easiest route to earth.
Shering approach the problem of lightning protection from the point of view of preventing damage from this dissipated energy. We do this by using a PATENTED loadcell assembly unit which fits an insulating component between the ground and the weighbridge deck. The dielectric properties of this insulator are such that it will restrict the voltage potential across the weighbridge and its load cells to less than 100V, which is the level the load cells can comfortably withstand without damage.
>Over 10 years of use on Shering weighbridges around the World has proved this insulator to be both electrically durable and structurally strong enough in the most arduous conditions.
