	■Application

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

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).
