DMT 2B/1 - Electronic earthing system (Resistive and capacitive)
Description:
The DMT 2B/1 Electronic Earthing System is composed of one
IIB+H2 aluminium alloy enclosure (EJB 6A type) inside which
there is an electronic resistance/capacity device and externally
a support hook, an earthing clamp, complete with 8 m of cable,
to measure and check the continuity towards the earth, aiming
to eliminate the electrostatic charges.
The DMT 2B/1 has (on the enclosure cover) a green and a red
pilot light as agreement or refuse to proceed.
Its modularity by dip switches placed on the electronic card, allows the selection of different capacity or resistance sensibility
levels.
