*: Use /HT option above +250°C, use /LT option below -29 °C, [ ]
for /MV option.
Specific conditions of use
• Electrostatic charges on the non-metallic parts
(excluding glass parts) or coated parts of the
equipment shall be avoided.
• The dielectric strength of at least 500 V a.c.
r.m.s. between the intrinsically safe circuits and
the enclosure of the flow meter or the converter
is limited only by the overvoltage protection.
• Because the enclosures of the flow meters
and the flow converter are made of aluminium
alloy, when used in an potentially explosive
atmosphere requiring apparatus of equipment
categoly 1 G, they must be installed so, that
even in the event of rare incidents, an ignition
source due to impact of friction between the
enclosure and iron/steel is excluded.
