ATEX earth monitoring system
The monitoring units are widely applicable and very trustworthy:
- Specific monitoring systems: detection of resistance or capacity
- Safe discharging of sparks with high energy level: inside the enclosures of the monitoring unit.
- Permanent electrostatic monitoring of the object.
- Intrinsically safe permanent guarding of the earth connection.
- Red/green signal lamps for local status indication of the earth connection.
- Volt-free contacts for remote control, for instance for turning on a pump.
