SYMEGA.VO
Grounding monitoring system
Symega grounding monitoring systems offer the best possible protection against electrostatic discharge during the process. Processes can be safely controlled or interrupted by continuously monitoring the resistance using grounding clamps and the potential-free changeover contacts connected to the monitoring system.
Application
As part of a progressive automation process Symega systems are primarily used in the process, chemical and pharmaceutical industries. They make a significant contribution to plant safety by protecting against electrostatic charge in potentially explosive atmospheres.
Advantages
- Easy on-site installation thanks to its compact design.
- Integrated signalling for reliable monitoring.
- Approved for use in hazardous areas zones 1 and 21.
- Maximum safety through potential-free changeover contacts that are fully integrated into the process control system.
Mechanism
The SYMEGA.VO grounding monitoring system establishes a safe connection between stationary and mobile, metallic or conductive and dissipative objects and a good earth. The built-in LEDs signal the actual status of the grounding process. Thanks to the two built-in potential-free changeover contacts, this status can be fully integrated into the process control system and therefore represents the highest possible level of safety. The measurement can be carried out in two variants: low-impedance for potential equalisation of 0-1 kΩ or 103 Ω for all metallic objects and high-impedance for potential equalisation of 0-3 MΩ or 3 x 106 Ω for type C big bags.
More types
SYMEGA.SI
Grounding monitoring system
The SYMEGA.SI grounding system is installed in the switch cabinet outside potentially explosive atmospheres. It establishes a safe connection between stationary and mobile, metallic or conductive objects and good grounding. The circuits for grounding and the LEDs are intrinsically safe and may be routed up to zones 0 and 20 in order to visualise the current status of the grounding process in the application to the user.
