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.
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 ... 95 % 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".
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.
The technical specifications contained in these operating instructions must be
observed. Improper handling or operation of the instrument outside of its technical
specifications requires the instrument to be taken out of service immediately and
inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary
to the intended use.
