Siemens SITRANS P DS III Operating Instructions Manual page 23

With appropriate parameter settings and the necessary add-on parts (e.g. flow limiters and
remote seals), the pressure transmitter can also be used for the following measurements:
● Level
● Volume
● Mass
● Volume flow
● Mass flow
The output signal is a process-based, digital PROFIBUS PA/FOUNDATION™ Fieldbus FF
signal.
You can install the "intrinsically-safe" or "flameproof enclosure" version of the pressure
transmitter in hazardous areas. The devices have an EC-Type Examination Certificate, and
comply with the corresponding harmonized European directives of the CENELEC.
The pressure transmitter is available with various designs of the remote seal for special
applications. A special application, for example, is the measurement of highly viscous
materials.
Gauge pressure
This version measures the gauge pressure of corrosive, non-corrosive and toxic gases,
vapors and liquids.
The smallest nominal measuring range is 0.01 bar g/1kPa g/14.5 psi g, the largest is
700 bar g/70 MPa g/10153 psi g.
Absolute pressure
This version measures the absolute pressure of corrosive, non-corrosive and toxic gases,
vapors and liquids.
There are two series: A "Differential pressure" series and a "Gauge pressure" series. The
"Differential pressure" series features a high overload capacity.
The smallest nominal measuring range of the "Differential pressure" series is
8.3 mbar a/0.83kPa/3.63 psi a, the largest is 100 bar a/10 MPa a/1450 psi a.
The smallest nominal measuring range of the "Gauge pressure" series is
8.3 mbar a/0.83kPa/3.63 psi a, the largest is 30 bar a/3 MPa/435 psi a.
Differential pressure and flow rate
This version measures corrosive, non-corrosive and toxic gases, vapors and liquids. You can
use it for the following types of measurement:
● Differential pressure
● Gauge pressure, suitable for small positive or negative pressure value
● In combination with a primary element: flow rate q ~
