Description

Gas density monitoring of electrical equipment
Gas density is a crucial operating parameter for high-voltage plants. If the required gas density is not present, safe operation of the plant cannot be guaranteed. The gas density monitor model GDM-RC-100 warns reliably when the gas density, due to leakage, drops below the established values, even under extreme environmental conditions.

Operating principle
The model GDM-RC-100 works according to the reference gas principle. The reference gas enables accurate isochore switching and display over the entire temperature range. Temperature changes and atmospheric pressure variations do not affect the measurement.

Everything at a glance
As in the case of the gas density monitor model GDM-100, for the model GDM-RC-100, WIKA also relies on the proven principle of a readily legible display. The entire density and

vacuum range can be displayed locally on only one dial with high accuracy. This increases safety during maintenance and service work on switchgear and simplifies implementation of this type of work.

Maximum plant safety through self-diagnostics
The welded reference chamber enables a very high long-term stability and eliminates drift. In the extremely unlikely case of leakage in the reference chamber, the plant operator is reliably warned by a switching signal of the instrument. The gas density monitor is maintenance-free.

Prepared for alternative gases
The model GDM-RC-100 can be used for any type of alternative gases and is capable of accurate isochore switching of these gases without any temperature effect.
