8 Mounting
Before installing the transmitter, check whether the device
design meets the requirements of the measuring point from a
measurement technology and safety specifications point of
view. This applies in respect of the:
— Measuring range
— Overload resistance
— Temperature
— Explosion protection
— Operating voltage
The suitability of the materials must be checked as regards
their resistance to the media. This applies in respect of the:
— Gasket
— Process connection, separating diaphragm, etc.
In addition, the relevant directives, regulations, standards, and
accident prevention regulations must be observed (e. g.,
VDE/VDI 3512, DIN 19210, VBG, Elex V, etc.).
Measurement accuracy is largely dependent on correct
installation of the transmitter and, if applicable, the associated
impulse line(s).
As far as possible, the measuring setup should be free from
critical ambient conditions such as large variations in
temperature, vibrations, or shocks.
IMPORTANT (NOTICE)
If unfavora
ble ambient conditions cannot be
avoided for reasons relating to building structure,
measurement technology, or other issues, the
measurement quality may be affected.
(See "Specifications" chapter).
If a remote seal with capillary tube is installed on the
transmitter, the additional operating instructions for remote
seals and the related data sheets must be observed.
8.1 IP rating
The housing of pressure transmitters of the R266 series
satisfies the requirements of IP degree of protection
IP 66 / IP 67 (NEMA 4X) in accordance with IEC 60529.
The first digit indicates the protection of the integrated
electronics against penetration of foreign objects, including
dust.
The digit “6” means that the housing is dust tight (i.e. dust
cannot penetrate). The second digit indicates the protection of
the integrated electronics against the penetration of water.
The digit “6” means that the housing is watertight and can
even withstand a strong water jet under the specified
conditions.
The digit “7” means that the housing is watertight and can be
temporarily immersed at a specified pressure and for a
specific time, without water penetrating.
8.2 Factory settings
The transmitter is factory configured according to the
customer’s order specifications.
IMPORTANT (NOTICE)
Under no
rmal
conditions no additional settings
are required.
The typical configuration includes:
— N
umber of the measuring point tag
— Calibrated span
— Configuration of the flow or liquid level calculation
— Configuration of the LCD display
