Siemens Pressure Measurement
Parmley Graham offers Siemens’ range of pressure measurement solutions designed for accurate and reliable measurement in industrial and commercial applications. Tailored to the specific requirements of your applications, Siemens pressure measurement devices provide the confidence you need in your instrumentation control.
Siemens’ primary pressure measurement line is branded under the SITRANS P series. The SITRANS P series includes various models, providing different types of pressure measurements such as absolute, gauge, and differential pressure.
Reliable. Accurate. Versatile. Low-maintenance.
Pressure Measurement under control with SITRANS P
Every process in your plant brings with it specific requirements. That’s why SITRANS P pressure transmitters are your complete range of measuring products with different levels of performance, varying load capacities and types of materials.
Uncompromising precision
SITRANS P pressure transmitters are a complete family of measuring instruments. They measure gauge, differential, and absolute pressure, including performance values, load capacities, and materials.
In addition to high measuring accuracy and ruggedness, the modular system features superb operating convenience and functionality. Whether it’s international approvals or industry standards, these transmitters meet the challenges of increasingly complex tasks in the process industries.
Safety included
You can select device versions that also offer comprehensive safety features. Warnings and alarms signal critical measured values for plant monitoring, while service or calibration intervals can be displayed predictively through self-diagnostics based on a maintenance scheduler.
Safety is integrated
Stringent safety requirements must be met in all areas and sectors of the process industries. One example is chemicals, and Siemens’ portfolio for pressure measurement unequivocally satisfies the high demands of the chemical industry (SIL 3). Thanks to comprehensive diagnostic functions, you always know whether your process is running according to plan and can intervene and correct it, if necessary, for example in reactors. They are part of the overall plant and must be seamlessly integrated into the process for maximum safety, efficiency, and availability. Interventions such as filling, heating, cooling, mixing, and the monitoring of all process conditions are performed on an ongoing basis. In addition, parameters such as pump performance, temperature, energy consumption, and emissions must be measured, analysed, and monitored.
SITRANS P Pressure Transmitters - Your complete range of measuring devices.
“High performance” version of the P320 for gauge and differential pressure measurements.
For measurement of gauge pressure, absolute pressure, differential pressure, flow, and level.
Converting the level-proportional hydrostatic pressure into standardised signal 4 to 20 mA.
Submersible sensor for hydrostatic level measurement with protective caps made of PPE, stainless steel and ETFE.
Accessories
Seals, Valves and Valve Blocks
We offer a range of fittings accessories for your pressure applications. These include:
- Shut-off Valves for gauge and absolute pressure transmitters
Used for shutting off and venting the measured medium line and for checking the connected pressure measuring device, gauge pressure transmitter or absolute pressure transmitter. - Shut-off valves for differential pressure
The shut-off valves for differential pressure transmitters are used for shutting off and venting the measured medium lines and for checking the connected differential pressure transmitter. - Remote Seals
For measuring viscous, corrosive or fibrous media (plus media at extreme temperatures). The remote seals can be used with the following pressure transmitters:- SITRANS P320/420
- SITRANS P300

The SITRANS P Advantage
For gases, liquids, and paste-like media, the gauge pressure, absolute pressure, and differential pressure must be measured constantly to detect values that are too low or a potential overload. Whether for pipelines, valves, or reactors, the SITRANS P transmitter family offers the right solution for every application.
The most important factor in selecting the right pressure transmitter is the required accuracy of the measuring range. SITRANS P transmitters offer a variety of choices from 0.04% to 0.3%. They are suitable for safety-related applications, with certifications according to SIL2 and SIL2/3. Numerous bus systems for communication are also supported, including HART®, PROFIBUS PA, and FOUNDATION Fieldbus. In addition, the transmitters have all the most current approvals and certificates. Our pressure measuring devices give you the instrumentation reliability you need to meet your own specific requirements.
