ATEX TERRALIGHT Ground Monitoring System
The TERRALIGHT ground monitoring system is designed for use when filling or discharging potentially explosive materials.
Description
The system effectively eliminates any static charges. This ATEX system monitors the connection to the bonding conductor and the contact across the ground clamps. TERRALIGHT is designed for connecting one ground clamp or a cable rewinder fitted with ground clamp.
