SITRANS P Siemens Pressure Transmitter

SITRANS P Siemens Pressure Transmitter is for Measuring Gauge Pressure, Absolute Pressure. It also can be used in Flow & Level measurement. DS III series featuring extensive user-friendliness and high accuracy. The parameterization is performed using control keys over HART communication, PROFIBUS-PA or FOUNDATION Fieldbus interface. Operation is very simple in spite of the numerous setting options. Transmitters with type of protection "Intrinsic safety", and "Explosion-proof" Dust Proof also can be installed within potentially explosive atmospheres (zone 1) or in zone 0.

Various versions of the DS III pressure transmitters are available for measuring:
• Gauge pressure
• Absolute pressure
• For differential pressure transmitters

SITRANS P Differential pressure transmitters, DS III series, 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.

The pressure transmitters of the DS III series can be used in industrial areas with extreme chemical and mechanical loads. Electromagnetic compatibility in the range 10 kHz to 1 GHz makes the DS III pressure transmitters suitable for locations with high electromagnetic emissions.

Diaphragm Seal Version
In many cases the pressure transmitter and the measured medium have to be physically separated. It is then necessary to use a remote seal.

Diaphragm seal
With diaphragm seals, the pressure is measured by means of a flat diaphragm which rests in a bed.

The following types of diaphragm seals exist:

Diaphragm seal of sandwich design without (left) and with a projecting diaphragm (tube)
• Sandwich design with projecting diaphragm (tube) to DIN or ASME which are secured using a dummy flange.

Diaphragm seal of flange design without (left) and with a projecting diaphragm (tube)
• Flange design with projecting diaphragm (tube) to DIN or ASME, secured using holes in the flange.
