Grounding device for railway applications EJB-A/B/KTM

for mobile tanks

The apparatus, by means of the clamp connected to conductive parts of tank truck, disperses to the ground the electrostatic charges generated during load and unload operations. The electronic unit of the apparatus verify the ground resistance, ad if it’s acceptable, allow round connection and it switches the SPDT contacts which enable/disable the pump of tanker and it is signaled by green light. Also available the EJB-B/KTM device complete with 2 clamps. The first electronic unit verify the ground resistance of the clamp 1, ad if it’s acceptable signaled by the green light 1, the second electronic unit verify the ground resistance of the clamp 1, ad if it’s acceptable signaled by the green light 2, in this case allow round connection and it switches the SPDT contacts which enable/disable the pump of tanker. In case of resistance conditions not suitable for the clamp 1 it will not be possible to proceed with the verification of the resistance conditions for the clamp 2.
