IP protection and designation
The housings for 266DDS transmitters are certified as
conforming to protection type IP66 / IP67 (according to
IEC 60529) or NEMA 4X (according to NEMA 250).
The first number indicates the type of protection the
integrated electronics have against the entry of foreign bodies,
including dust.
"6" means that the housing is dust-proof (i.e., no ingress of
dust).
The second number indicates the type of protection the
housing has against the entry of water.
"6" means that housing is protected against water; specifically,
powerful jets of water under standardized conditions.
"7" means that the housing is protected against the effects of
temporary immersion in water under standardized water
pressure and temporal conditions.
The device and its accessories (i.e. cable glands and other
electrical connections) must be carefully and duly tightened to
meet expected IP protection type.
When using/mounting cable glands, they have to meet
expected IP rating.
Mounting the transmitter
Transmitter factory configuration consideration
The 266DDS pressure transmitter in your hands has been
factory calibrated to reflect the published declared
performance specification; no further calibration is required in
normal condition. ABB typically configures 266DDS pressure
transmitters according to the user requirements. A typical
configuration includes:
• TAG number
• Calibrated span
• Output linearization
• LCD display configuration
Hazardous area considerations
The transmitter must be installed in hazardous area only if it is
properly certified. The certification plate is permanently fixed
on the housing of the transmitter. Transmitter can have the
following certifications:
• ATEX Europe (code E2) approval
• IECEx (code E9) approval
• Combined FM (code EB) approvals (US and Canada)
Type 4X, IP66, IP67 for all above markings.
Technical Regulations Customs Union EAC (Russia,
Kazakhstan, Belarus), Inmetro (Brazil), NEPSI (China).
See relevant paragraph for complete markings details.
Pressure Equipment Directive (PED)
(2014/68/EU)
Devices with PS >200
Devices with a permissible pressure PS >200 bar have been
subject to a conformity validation. The data label includes the
following specifications: Pressure Equipment Directive (PED)
(2014/68/EU).
Devices with PS ≤ 200
Devices with a permissible pressure PS ≤200 bar correspond
to article 4 paragraph 3. They have not been subject to a
conformity validation. These instruments were designed and
manufactured according to SEP Sound Engineering Practices.
