; it
is not assigned an ID in the sense of the ATEX Directive.
9.2 Areas of use
The units can be used as follows:
In the Zone 2 (Gas-Ex, Cat. 3G) into explosion group of IIA, IIB and IIC
In the Zone 22 (Dust-Ex, Category 3D) at non-conductive dusts with a
minimum igniting energy of > 3 mJ
In the Zone 1 (Gas-Ex, Cat. 2G) into explosion group of IIA, IIB and IIC
In the Zone 21 (Dust-Ex, Category 2D) at non-conductive dusts with a
minimum igniting energy of > 3 mJ
In normal use, the rotor flow indicators are
completely filled with medium
.
Zone 2 – or Zone 1 – conditions may prevail for a short time.
9.3 Evaluation
Adherence to EN 13463, Parts 1 to 8 (Mechanical Explosion Prevention)
When used properly, the rotor flow indicator does not have its own potential
source of ignition as per the conditions of Categories 2 and 3. It does however
fulfil the following requirements:
The manufacturer has subjected all exposed parts of the device to the impact
and environmental strain tests pursuant to EN 13463-1.
When installed, the device must be protected against external
energy impact – or measures should be taken to take into account
any possible zone violations in the system.
The outer casing of the device is made of brass or stainless steel and
borosilicate glass; there are no light metal parts.
