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-63 gas density monitor finds its use.
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 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 ... 90 % non-condensing (per DIN 40040)
■
The strength of the measuring instrument (enclosing non-metal parts) was tested
■
with a reduced impact energy of 2 J corresponding to IK07 per EN 61010-1:2010.
The IK code is included on the respective product label.
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".
