3.2 Intended use
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-100 gas density monitor finds its use. The
transmitter transmits the measured gas density as an electrical signal.
Gas density monitors are modified contact pressure gauges, specially developed for the
use of SF₆ gas. Temperature influences acting on the enclosed SF₆ gas are compensat-
ed by a compensation system.
The gas density monitors are specially designed for the respective application in switch-
gear (pure SF₆ gas, gas mixtures, calibration pressure, switch points ...). Before use,
check whether this instrument is suitable for the intended application.
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!
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
