คำอธิบาย

Product detail:

EARTHING CONTROL SYSTEM allows safe loading and off-loading of mobile tanks (trucks, wagons , trolleys and big bags) in which flammable products are stored . The high speed process could generate electrostatic charges with possible risks of sparks and explosions. To avoid the accumulation of static electricity, the system constantly verifies the grounding connection and allows the loading process only if safety parameters are fully respected.

The Earthing Control System is housed in a GUB/GUBA or an EJB enclosure, available in copper-free aluminium alloy finished with epoxy-coating RAL 7001 or, for highly-corrosive environment, in stainless steel.

GUB/GUBA housing is suitable for the IIC Group Protection while EJB housing is suitable for II+H2 Group Protection (any gas with the sole exclusion of Acetylene). The connection to the clamp is performed through an intrinsically safe circuit.

The electronic control unit is available in different versions, covering the different applications:

  • RESISTIVE : a low resistance R is detected between the two clamp jaws;
  • RESISTIVE & CAPACITIVE : in addition to low resistance,the truck’s capacitance is also monitored.

The standard parameters of electronic control units can be adjusted on demand. The system can be equipped, upon request, with a by-pass key switch, operated only by authorized personnel, to force the CAPACITIVE mode in extreme wet conditions.
