The causes of electrostatic charging on systems and devices are different: Fundamentally, there is a distinction between the movement of solid and liquid surfaces against each other, the separation between solid surfaces, electrostatic induction, liquid atomization, and solidification potential. Consistent grounding monitoring can protect from this danger.
The driver of a tank truck delivers raw materials to a chemical factory. The loading station is equipped with simple grounding clamps, which the driver uses. He carefully attaches the grounding clamps to his tank vehicle. Unfortunately he decides to use a plastic part on the chassis of his trailer for this. The vehicle is completely ungrounded. During unloading the vehicle is charged electrostatically, and a strong discharge occurs which could lead to the ignition of an explosive mixture.
With the grounding monitoring device FARADO®, it is possible to indicate the functioning potential equalization through an extremely bright illuminated LED signal. Furthermore, the switching outputs can be used to actuate certain components, for example, to switch pumps on or off. Dangerous, charge-generating processes can therefore be stopped immediately.
Avoid ignition sources through permanent grounding monitoring!
The FARADO® grounding system will ensure the safe loading and unloading of flammable products for mobile tanks (TKW, silo vehicles, wagons). Electrostatic charges can develop on the surface of non-conductive materials through friction with other materials. This charge remains on the material until it either slowly degrades or discharges through an arc to a conductor.
The sparks which develop from this discharge (high-voltage, several 1,000 volts!) can cause an ignition in the event of an explosive atmosphere.
FARADO® I for truck grounding
In order to prevent this electrostatic charge, the two-pole grounding clamp is simply attached to the metal container concerned. The FARADO® grounding system independently checks the proper grounding, as well as the capacity of the object to be grounded, and enables the loading process. Through this, it is possible to avoid dangerous situations through failures and human error.
The FARADO® grounding system was developed on the basis of the ATEX 2014/34/EU directive, with the EEx-d[ia] type of protection, and corresponds to the protection class IP66.
