3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or damage to property or the
environment, if not avoided.
Information
... points out useful tips, recommendations and information for ecient and trouble-free operation.
3.2 Intended use
The pressure sensor is used for measuring pressure. The measured pressure is output as an electrical signal.
This is class B equipment for emissions and is intended for use in industrial environments. In other environments,
e.g. residential or commercial installations, it can interfere with other equipment under certain conditions. In such
circumstances the operator is expected to take the appropriate measures.
Only use the pressure sensor in applications that lie within its technical performance limits (e.g. max. ambient
temperature, material compatibility, ...).
→ For performance limits see chapter 9 “Specications”.
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

3. Safety
3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
▶
Refrain from unauthorised modifications to the instrument.
▶
Do not use the instrument within hazardous areas.
▶
Do not use the model D-20-9 with abrasive or viscous media.
Any use beyond or dierent to the intended use is considered as improper use.
Do not use this instrument in safety or emergency stop devices.
3.4 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids, and refrigeration
plants, compressors, etc., in addition to all standard regulations, the appropriate existing codes or
regulations must also be followed.
WARNING!
Residual media in dismounted pressure transmitters can result in a risk to persons, the environment and
equipment.
Take sucient precautionary measures.
3.5 Personnelqualication
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of country-specic regula-
tions, current standards and directives, are capable of carrying out the work described and independently recognising
potential hazards.

4. Transport, packaging and storage / 5. Commissioning, operation
4. Transport, packaging and storage
4.1 Transport
Check the pressure sensor for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
4.2 Packaging and storage
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).
In order to protect the diaphragm, provide the process connection of the model D-21-9 with the supplied protection cap.
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +100 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
5. Commissioning, operation
5.1 Mechanical mounting
Only use the pressure sensor if it is in perfect condition with respect to safety.
Prior to commissioning, the pressure sensor must be subjected to a visual inspection.
■
Leaking uid is indicative of damage.
■
The diaphragm at the process connection of the model D-21-9 is a safety-relevant component and must not be
damaged.
Requirements for mounting point
The mounting point must meet the following conditions:
■
Sealing faces are clean and undamaged.
■
Sucient space for a safe electrical installation.
■
For information on tapped holes and welding sockets, see Technical information IN 00.14 at www.wika.com.
■
Permissible ambient and medium temperatures remain within the performance limits. Consider possible restrictions
on the ambient temperature range caused by mating connector used.
→ For performance limits see chapter 9 “Specications”

5. Commissioning, operation
Sealing variants
The max. torque depends on the mounting point (e.g. material and shape). If you have any questions,
please contact our application consultant.
→ For contact details see chapter 1 “General information” or the back page of the operating instructions.
1. Seal the sealing face (→ see “Sealing variants”).
2
.
At the mounting point, screw the pressure sensor in hand-tight.
3
.
Tighten with a torque spanner using the spanner ats.
5.2 Electrical mounting
Requirements for voltage supply
→ For power supply see product label
The power supply for the pressure sensor must be made via an energy-limited electric circuit in accordance with
section 9.4 of UL/EN/IEC 61010-1 or an LPS to UL/EN/IEC 60950-1 or class 2 in accordance with UL1310/UL1585
(NEC or CEC).
Parallel threads
Seal the sealing face with flat gasket, lens-type
sealing ring or WIKA profile sealing.
per EN 837 per DIN 3852-E
Tapered threads
Wrap threads with sealing material
(e.g. PTFE tape).
