Pressure Measuring Instruments

Overview of the SITRANS P range:

SITRANS P MPS

For convenient hydrostatic level

measurements

The SITRANS P transmitter, MPS series, is

used for hydrostatic level measurements.

It is immersed into the medium to be mea-

sured by hanging on a cable. The sensor

has a stainless steel enclosure and is suit-

able for applications ranging from drinking

water up to corrosive liquids.

SITRANS P Z

The single-range transmitter for relative

and absolute pressures

Two types of pressure sensor are used in

the Series Z: a stainless steel sensor and

a sensor with ceramic diaphragm. One

version of the Series Z is designed for the

requirements of the compressor and pump

industry with brass enclosure.

SITRANS P ZD

Transmitter with digital display and stain-

less steel enclosure

The SITRANS P ZD digital pressure transmit-

ter is provided with a display and a facility

for turndown by 10:1. The enclosure as

well as the process connection are made of

stainless steel. The digital display is avail-

able either radially or axially to the process

connection.

SITRANS P Compact

For the special requirements of the F&B, phar-

maceutical and biotechnology industries.

The SITRANS P Compact is an analog trans-

mitter which has been specially developed

for the requirements of the food & bever-

age, pharmaceutical and biotechnology

industries. The design corresponds to the

hygiene requirements of EHEDG, FDA, and

GMP. The increased hygiene demands are

satisfi ed by a wide range of aseptic stain-

less steel process connections as well as

stainless steel housing. Cleaning and steri-

lization procedures (CIP, SIP) are handled

without problem.

SITRANS P300

The reference unit in stainless steel

housing

The SITRANS P300 stands for measuring

precision and ruggedness, and primarily

for an advanced operating concept. The

SITRANS P300 carries over these proven

virtues into the food and beverage indus-

try as well as pharmaceutical processes. It

is an integral component of the SITRANS P

range as a result of its maximum deviation

in measurement of 0.075 %, a hygienic

stainless steel housing with lasered rating

plate, and the proven SITRANS P DS III local

operating philosophy.

Cleaning (CIP) and sterilization (SIP) of the

process volume during measuring mode

are handled without drift at a specifi ed

temperature range of 302 °F (150 °C). You

are supported in evaluation of your clean-

ing processes by the drag pointers which

record the min./max. values of the sensor

SITRANS P is a complete range of instruments for measuring relative, differential and abso-

lute pressure. In addition to high measuring precision and ruggedness, convincing features

include the operating convenience and functionality of the modular system as well as the

perfect safety concept. In other words, we have a proven range of products for all applications.

for example food and beverage

temperature. You can read out the process

data via a HART or PROFIBUS PA interface.

The SITRANS P300 is available combined

with absolute or relative pressure measur-

ing cells. The range of process connections

covers those for the food and beverage

industry, pharmaceutical, and paper indus-

tries, up to classical threaded and fl anged

versions.

SITRANS P DS III

Digital transmitters with integral diagnos-

tics function, HART or PROFIBUS PA com-

munication, and convenient key operation

Within a range from 1 mbar to 400 bar,

the SITRANS P DSIII line has no problem

whatsoever with extreme chemical and

mechanical loads or electromagnetic infl u-

ences. It offers additional safety functions

such as plant and self-monitoring, fault

diagnostics and signaling when the next

calibration is due. The self-test function is

unique for fail-safe operation. Measuring

cells can be replaced in no time, meaning

that repairs on site are fast, simple and

cost-saving. In addition to convenient local

operation, SITRANS P transmitters can be

fully remote-controlled digitally using the

PROFIBUS PA, Foundation Fieldbus or HART

protocol.

SITRANS P DSIII is designed for nominal

pressures up to PN 420. The wetted parts

Communication and Software

The “Totally Integrated Automation” platform concept has made perfect interplay between

all the components and functions in a process a reality. The prerequisite is powerful software

such as SIMATIC PDM which provides optimum support for commissioning, maintenance

and diagnostics of all fi eld devices known as Asset Management.

SIMATIC PDM

SIMATIC PDM (Process Device Manager) is a

universal, manufacturer-independent tool

for planning, confi guring, commissioning,

diagnosing and maintaining intelligent fi eld

devices (sensors and actuators) and fi eld

components (remote I/Os, multiplexers,

maintenance devices, compact regulators).

Over 1200 process devices by more than 100

manufacturers are supported by SIMATIC PDM.

The construction and function of the de-

vices can be described using the Electronic

Device Description Language (EDDL), based

on the leading EDD international standard

(Electronic Device Description; IEC 61804).

SIMATIC PDM utilizes this to automatically

create an easy-to-use user interface with the

corresponding information about the process

devices. The extension and standardization

of the EDDL into Enhancement Levels 1 and 2

means a wide range of important functions

are available in the EDD, including the OPC

unifi ed architecture.

Communication with process devices is by

HART, PROFIBUS or alternative protocols.

HART – fi eld communications protocol

The HART® communication standard is widely

used for fi eld devices. HART devices are

defi ned by the HCF (HART Communication

Foundation). The HART standard extends

analog 4 – 20 mA signals to modulated, indus-

try-quality, digital HART signals. The advan-

tage is the combination of tried-and-tested

measurement-value transfer and simultaneous

digital communication with bi-directional,

acyclic transfer. This allows transfer of diag-

nosis, maintenance and process information

from fi eld devices to higher-level systems.

Standardized parameter sets can be used for

the manufacturer-independent operation

of all HART devices. HART device descriptions

(EDD) are used to integrate HART devices into

the SIMATIC PDM. This guarantees simple

operation and commissioning of fi eld devices,

even in isolated locations.

PROFIBUS

Decentralized automation solutions based on

open fi eld busses are currently standard in

many areas of the production and process

industry. The advantages of digital communi-

cation can only be fully utilized in connection

with fi eld buses, including a higher resolution

of measurement values, diagnostic options

and remote parameterization. PROFIBUS is

currently the most successful open fi eld bus,

providing a fl exible platform for a variety of

applications. Based on the IEC 61158 stand-

ard, it is a reliable investment and suitable

for fast communication in production and

process automation. It is the fi rst fi eld bus

and fulfi lls the requirements of both branches

with the same communication performance.

PROFIBUS PA is tailored to the requirements

of the process industry.

ASSET MANAGEMENT

Asset Management comprises all activities

and measures that serve to maintain or

increase the value of a plant. This primarily

includes value-conserving and value-increas-

ing maintenance and servicing (plant-specifi c

Asset Management), in addition to business

management, process management and

process optimization.

SIMATIC PDM is particularly suited to plant-

specifi c Asset Management due to its com-

prehensive functionality for planning,

confi guring, commissioning, diagnosis and

maintenance of intelligent fi eld devices and

components. To provide meaningful and

reliable results, Asset Management Systems

require large amounts of basic information.

SIMATIC PDM can provide the device data

relevant for plant-specifi c Asset Management

and transfer it to higher-level Asset Manage-

ment Systems in XML format via a uniform in-

terface. It is based on the device descriptions

(EDD) that are independent of the operating

system. Extraction of information and inter-

pretation of results are independent of the

type of device, i.e. it is irrelevant whether the

device is an actuator or sensor, a PROFIBUS

or a HART device. However, SIMATIC PDM is

more than just a data logger for higher-level

Asset Management systems. It offers

a large number of Asset Management

functions in itself.

Perfect cooperation between all compo-

nents and functions:

Totally Integrated Automation (TIA) from

Siemens offers a uniform portfolio of prod-

ucts and systems for the process industry.

The core of the system is the SIMATIC PCS 7

process control system. Standard SIMATIC S7

components and software packages for

typical process-automation functions

provide the basis for the functionality of

SIMATIC PCS 7. The defi ning feature of

Totally Integrated Automation is its unique

uniformity. Thus, SIMATIC PCS 7 offers you:

Uniform data management

Uniform communication

Uniform software for confi guring and

programming
