2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate pressure transmitter
has been selected in terms of measuring range, design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
WARNING!
Open the connections only after the system has been depressurised.
Further important safety instructions can be found in the individual chapters of these operating
instructions.
2.1 Intended use
The pressure transmitter is used to convert pressure into an electrical signal.
The instrument is exclusively intended for use in an industrial environment. In residential areas, measures for
radio interference suppression may have to be taken.
The technical specications contained in these operating instructions must be observed. Improper handling or
operation of the pressure transmitter outside of its technical specications requires the instrument to be taken
out of service immediately and inspected by an authorised Festo service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

4. Design and function
4.1 Description
By means of a sensor element and by applying power, the prevailing pressure is converted into an amplied
standardised electrical signal via the deformation of a diaphragm.This electrical signal varies in proportion to
the pressure and can be evaluated accordingly.
5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.

5. Transport, packaging and storage / 6. Commissioning, operation
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site,
sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +80 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
WARNING!
Before storing the pressure transmitter (following operation), remove any residual media.This is
of particular importance if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic,
radioactive, etc.
6. Commissioning, operation
Required tool: SW 27 open-ended spanner
CAUTION!
Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
■
Leaking uid is indicative of damage.
■
Only use the pressure transmitter if it is in perfect condition with respect to safety.
6.1 Making the mechanical connection
■
Only ever screw in, or unscrew, the instrument via the spanner ats and to the prescribed torque using an
appropriate tool.The correct torque depends on the dimensions of the process connection and the sealing
used (form/material).When screwing in or unscrewing the instrument, do not use the case as a working
surface.
■
When screwing in, do not cross the threads.

12 Pressure transmitter SPTW
EN
14012402.03 03/2015
6.2 Making the electrical connection
■
The instrument must be earthed via the process connection.
■
The power supply for the pressure transmitter must be made via an energy-limited electrical circuit per
UL/EN/IEC 61010-1 or an LPS to UL/EN/IEC 60950-1 or class 2 per UL1310/UL1585 (NEC or CEC).The
power supply must be suitable for operation above 2,000 m should the pressure transmitter be used at this
altitude.
■
Only ever use a power source that ensures a safe electrical isolation of the operating voltage in accordance
with IEC/DIN EN 60204-1. In addition, observe the general requirements for PELV circuits in accordance
with IEC/DIN EN 60204-1. Switching power supply units are permissible, if they ensure a safe isolation as
dened by IEC/EN 60950-1.
■
Long signal lines reduce the immunity to interference. Ensure that the length of the signal cable is always
shorter than 30 m. In this way you can avoid non−operate currents caused by electromagnetic interference.

The stated ingress protection only applies when plugged in using mating connectors
that have the appropriate ingress protection.
6.3 Functional check
The output signal must be proportional to the prevailing pressure. If this is not the case, this may
indicate a damaged diaphragm. In this case, see chapter „8. Faults“.

WARNING!
■
Only open the connections once the system has been depressurised
■
Observe the working conditions in accordance with chapter "3. Specications".

6.4 Accessories
Accessories can be found online at www.festo.com/catalogue.
7. Maintenance and cleaning
7.1 Maintenance
This instrument is maitenance-free. Repairs must only be carried out by the manufacturer.
7.2 Cleaning
CAUTION!
■
Before cleaning, correctly disconnect the instrument from the pressure supply, switch it o and
disconnect it from the mains.
■
Clean the instrument with a moist cloth.
■
Wash or clean the dismounted instrument before returning it in order to protect personnel and
the environment from exposure to residual media.
■
Residual media in dismounted instruments can result in a risk to persons, the environment and
equipment. Take sucient precautionary measures.
■
Do not use any pointed or hard objects for cleaning, since the diaphragm of the process
connection must not be damaged.
For information on returning the instrument see chapter „9.2 Return“.

8. Faults
First ensure that the system is under pressure (open valves/ball valves etc.) and that the correct power supply
and correct wiring type (2-wire/3-wire) has been selected.
Faults Causes Measures
No output signal Cable break Check the through drilling
Deviating zero point signal Overpressure safety exceeded Observe the permissible overpressure safety
(see Chapter "3. Specications")
Deviating zero point signal Too high/low working temperature Observe the permissible temperatures
(see Chapter "3. Specications")
Constant output signal upon change in
pressure
Mechanical overload caused by overpressure Replace instrument; if it fails repeatedly,
contact the manufacturer
Signal span too small Mechanical overload caused by overpressure Replace instrument; if it fails repeatedly,
contact the manufacturer
Signal span varies EMC interference sources in the environment;
for example, frequency converter
Shield instrument; cable shield; remove source
of interference
Signal span varies/inaccurate Too high/low working temperature Observe the permissible temperatures
(see Chapter "3. Specications")
Signal span drops/too small Signal span drops/too small Contact manufacturer and replace instrument
CAUTION!
If faults cannot be eliminated by means of the measures listed above, the instrument must be
shut down immediately, and it must be ensured that pressure and/or signal are no longer present,
and it must be prevented from being inadvertently put back into service. In this case, contact the
manufacturer. If a return is needed, follow the instructions given in chapter "9.2 Return".
