3.2 Intended use

The intended use of model GDM-RC-100 is to monitor the gas density of insulating
gases.
Wherever the gas density of SF₆ gas has to be indicated locally and, at the same time,
circuits need to be switched, the model GDM-RC-100 gas density monitor finds its use.
Gas density monitors are modified pressure measuring instruments with switch
contacts, specially developed for the use of SF₆ gas and other insulating gases.
Temperature influences acting on the enclosed gas are compensated by a
compensation system.
The gas density monitors are specially designed for the respective application in
switchgear (pure SF₆ gas, gas mixtures, calibration pressure, switch points ...). Before
use, check whether this instrument is suitable for the intended application.
The insulation values (air gaps and creepage distances) are sized for the following
ambient conditions in accordance with EN 61010-1:2010:
Altitude up to 2,000 m
■
Overvoltage category II
■
Pollution degree 2
■
Relative humidity: 0 ... 95 % non-condensing (per DIN 40040)
■
Only use the instrument in applications that lie within its technical performance limits
(e.g. max. ambient temperature, material compatibility, ...).
→ For performance limits, see chapter 9 "Specifications".
This instrument is not permitted to be used in hazardous areas!
