Notes on warranty
1.6 Transportation and storage
To guarantee sufficient protection during transport and storage, observe the following:
● Keep the original packaging for subsequent transportation.
● Devices/replacement parts should be returned in their original packaging.
● If the original packaging is no longer available, ensure that all shipments are properly
packaged to provide sufficient protection during transport. Siemens cannot assume
liability for any costs associated with transportation damages.
The packaging only provides limited protection against moisture and infiltration.
• Provide additional packaging as necessary.
Special conditions for storage and transportation of the device are listed in "Technical data"
(Page 193).
The contents of this manual shall not become part of or modify any prior or existing
agreement, commitment or legal relationship. The sales contract contains all obligations on

Requirements for special applications
Note
Operation under special ambient conditions
We highly recommend that you contact your Siemens representative or our application
department before you operate the device under special ambie
encountered in nuclear power plants or when the device is used for research and
development purposes.
2.2 Improper device modifications

• Only use equipment that is approved for use in the intended hazardous area and
labelled accordingly.
Technical data (Page 193)
If the device has already been operated in non-intrinsically safe circuits or the electrical
specifications have not been observed, the safety of the device is no longer ensured for use
in hazardous areas. There is a danger of explosion.
• Connect the device with type of protection "Intrinsic safety" solely to an intrinsically safe
circuit.
• Observe the specifications for the electrical data on the certificate and/or in Chapter
"Technical data (Page 193)".

WARNING
Risk of explosion due to electrostatic charge
2.4 Use in hazardous areas
Devices and their associated device parts are either approved for different types of
protection or they do not have explosion protection. There is a danger of explosion if device
parts (such as covers) are used for devices with explosion protection that are not expressly
suited for this type of protection. If you do not adhere to these guidelines, the test
certificates and the manufacturer warranty will become null and void.
• Use only device parts that have been approved for the respective type of protection in
the potentially explosive environment. Covers that are not suited for the "explosionproof" type of protection are identified as such by a notice label attached to the inside of
the cover with "Not Ex d Not SIL".
• Do not swap device parts unless the manufacturer specifically ensures compatibility of
these parts.
To prevent the build-up of an electrostatic charge in a hazardous area, the key cover must
be closed during operation and the screws tightened.
The key cover may be opened temporarily at any time for the purposes of operating the
pressure transmitter, even during plant operation; the screws should then be tightened
again.

Electrostatic-sensitive devices
NOTICE
Electrostatic-sensitive devices
2.4 Use in hazardous areas
The device contains electrostatic-sensitive devices (ESD). ESD can be destroyed by
voltages far too low to be detected by humans. These voltages can occur if you simply
touch a component part or the electrical connections of a module without being
electrostatically discharged. The damage to a module caused by overvoltage cannot
normally be detected immediately; it only becomes apparent after a longer period of
operating time has elapsed.
Protective measures against the discharge of static electricity:
• Make sure that no power is applied.
• Before working with modules, make sure that you discharge static from your body, for
example by touching a grounded object.
• Devices and tools used must be free of static charge.
• Hold modules only by their edges.
• Do not touch connector pins or conductor tracks on a module with the ESD notice.

3.2 Application
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.
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.
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.
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 ~

The smallest nominal measuring range is 20 mbar (8.03 in H2O), the largest is
30 bar (435 psi).
This version with mounting flange measures the level of non-corrosive, corrosive and toxic
liquids in open and closed containers. The smallest nominal measuring range is
250 mbar (3.63 psi), the largest is 5 bar (72.5 psi). The nominal diameter of the mounting
flange is DN 80 or DN 100, or 3" or 4".
For the level measurement on open containers, the low-pressure side of the measuring cell
remains open. This measurement is referred to as "Measurement against atmospheric
pressure". For the measurement on closed containers, the low-pressure side is usually
connected to the container. This balances out the static pressure.
The parts wetted by the medium are made of various materials according to the corrosion
resistance required.
These instructions describe the pressure transmitters SITRANS P DS III and
SITRANS P410. The main difference of the SITRANS P410 is the higher measuring
precision compared to the SITRANS P DS III. Refer to the information in the section
Technical data (Page 193).
You order SITRANS P410 using the order option C41 for specific device versions.
Depending on a customer-specific order, the device comprises different parts.

The inlet pressure (pe) is transferred to the gauge pressure sensor ⑥ via the seal diaphragm
④ and the fill fluid ⑤, displacing its measuring diaphragm. The displacement changes the
resistance of the four piezoresistors (bridge circuit) of the gauge pressure sensor. The
change in the resistance causes a bridge output voltage proportional to the inlet pressure.
Pressure transmitters with spans ≤ 6.3 MPa measure the inlet pressure against atmosphere,
those with spans ≥ 16 MPa the inlet pressure against vacuum.
