SITRANS P300 and DS III series

with PMC connection - Technical description

• Small long-term drift

■Overview

• 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 SITRANS P300 and DS III pressure transmitters have been

fitted with special process connections for the paper industry.

The pressure transmitter can be operated locally over 3 control

With the two process connection threads 1½" and 1" flush at the

keys or programmed externally over HART communication or

front, the SITRANS P300 and DS III transmitters can be used for

all processes in the paper industry.

cision casting. A round cover is screwed on at the front and rear

of the housing. The front cover (6) can be fitted with a viewing

pane so that the measured values can be read directly on the

digital display. The inlet (4) for the electrical connection is lo-

cated either on the left or right side. The unused opening on the

opposite side is sealed by a blanking plug. The protective earth

connection is located on the rear of the housing.

The electrical connections for the power supply and screen are

accessible by unscrewing the rear cover. The bottom part of the

housing contains the measuring cell with process connection

(1). The measuring cell is prevented from rotating by a locking

screw (8). As the result of this modular design, the measuring

cell and the electronics can be replaced separately from each

other. The set parameter data are retained.

At the top of the housing is a plastic cover (5), which hides the

input keys.

¹⁾ When the manufacture’s certificate M (calibration certificate) has to be

ordered for transmitters with diaphragm seals, it is recommended only to

order this certificate exclusively with the diaphragm seals. The measuring

accuracy of the total combination is certified here.

²⁾ Whe the acceptance test certificate 3.1 for transmitters with direct-con-

nected diaphragm seals is ordered, this certificate must also be ordered

with the corresponding seals.
