Overview
The SITRANS P300 and DS III pressure transmitters have been
fitted with special process connections for the paper industry.
With the two process connection threads 1½" and 1" flush at the
front, the SITRANS P300 and DS III transmitters can be used for
all processes in the paper industry.
SITRANS P300 and DS III series pressure transmitters are digital
pressure transmitters featuring extensive user-friendliness and
high accuracy. The parameterization is performed using control
keys, over HART communication, PROFIBUS PA or
FOUNDATION Fieldbus interface (DS III only).
Extensive functionality enables the pressure transmitter to be
precisely adapted to the plant’s requirements. Operation is very
simple in spite of the numerous setting options.
Transmitters with type of protection "Intrinsic safety" and "Explo-
sion-proof" may be installed within potentially explosive atmo-
spheres (zone 1) or in zone 0. The transmitters are provided with
an EC type examination certificate and comply with the corre-
sponding harmonized European standards (ATEX).
Various versions of the pressure transmitters are available for
measuring:
• Gage pressure
• Filling level
• Volume level
• Mass level
■
Benefits
• High quality and long life
• High reliability even under extreme chemical and mechanical
loads, e.g. abrasion.
• For aggressive and non-aggressive gases, vapors and liquids
• Extensive diagnosis and simulation functions
• Minimum conformity error
• Small long-term drift
• Wetted parts made of Hastelloy
• Infinitely adjustable spans from 30 mbar g to 16 bar g for DS III
with HART interface
• Nominal measuring range from 1 mbar g to 16 bar g for DS III
with PROFIBUS PA and FOUNDATION Fieldbus interface
• Infinitely adjustable spans from 30 mbar g to 16 bar g for
SITRANS P300 with HART interface
• Nominal measuring range from 1 bar g to 16 bar g for
SITRANS P300 with PROFIBUS PA interface
• High measuring accuracy
• Parameterization over control keys and HART communication,
or over PROFIBUS PA or FOUNDATION Fieldbus interface (DS
III only).

Application
The pressure transmitters of the DS III series, can be used in in-
dustrial areas with extreme chemical and mechanical loads.
Electromagnetic compatibility in the range 10 kHz ... 1 GHz
makes the DS III pressure transmitters suitable for locations with
high electromagnetic emissions.
Pressure transmitters with type of protection "Intrinsic safety" and
"Explosion-proof" may be installed within potentially explosive at-
mospheres (zone 1) or in zone 0. The pressure transmitters are
provided with an EC type examination certificate and comply
with the corresponding harmonized European standards
(ATEX).
Pressure transmitters with the type of protection "Intrinsic safety"
for use in zone 0 may be operated with power supply units of cat-
egory "ia" and "ib".
The transmitters can be equipped with various designs of re-
mote seals for special applications such as the measurement of
highly viscous substances.
The pressure transmitter can be operated locally over 3 control
keys or programmed externally over HART communication or
over PROFIBUS PA or FOUNDATION Fieldbus interface (only
DS III).
