1. Important details for your information
Read these operating instructions before installing and starting the pressure transmitter. Keep
the operating instructions in a place that is accessible to all users at any time.
The following installation and operating instructions have been compiled by us with great care
but it is not feasible to take all possible applications into consideration.These installation and
operation instructions should meet the needs of most pressure measurement applications. If
questions remain regarding a specic application, you can obtain further information:

If the serial number on the product label and/or the 2D code on the hexagon gets illegible (e.g. by
mechanical damage or repainting), the retraceability of the instrument is not possible any more.
WIKA pressure transmitters are carefully designed and manufactured using state-of-the-art
technology. Every component undergoes strict quality and environmental inspection before
assembly and each instrument is fully tested prior to shipment. Our environmental management
system is certied to DIN EN ISO 14001.

1.1 Intended use E-10, E-11:
Use the pressure transmitter with ameproof enclosure to transform pressure into an electrical
signal in gas hazardous areas, zones 1 and 2.
ATEX und IECEx approval
Pressuremeasuring instrument approved for use in gas hazardous areas, type tested in
accordance with the following standards:
■
EN 60079-0 / IEC 60079-0
■
EN 60079-1 / IEC 60079-1
ATEX Approval ratings: Flameproof enclosure II 2G Ex db IIC T6...T1 Gb (KEMA 05 ATEX 2240 X)
IECEx Approval ratings: Flameproof enclosure Ex db IIC T6...T1 Gb (IECEx DEK 15.0048X)
1.2 Knowledge required
Skilled personnel 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 regulations, current standards and directives, are capable of carrying out the
work described and independently recognising potential hazards.
It has to be acquainted with the rules and regulations on hazardous areas and electric circuits,
since this transducer is „electrical equipment“ as dened by EN 60079-14.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

The product complies with the requirements of the European directive (ATEX) on
explosion protection.
2-wire Two connection lines are intended for the voltage supply.
The supply current is the measurement signal.
3-wire Two connection lines are intended for the voltage supply.
One connection line is intended for the measurement signal.
3. Function
E-10: Pressure connection with internal diaphragm (standard version).
E-11: Pressure connection with ush diaphragm or highly viscous or solids entrained media
which might clog the pressure port.
Function
The pressure prevailing within the application is transformed into a standardised electrical signal
through the deection of the diaphragm, which acts on the sensor element with the power supply
fed to the transmitter.This electric signal changes in proportion to the pressure and can be evalu-
ated correspondingly.

4. For your safety
WARNING
■
Select the appropriate pressure transmitter with regard to scale range, perfor-
mance and specic measurement conditions prior to installing and starting the
instrument.
■
Observe the relevant national regulations and observe the applicable
standards and directives for special applications (e.g. with dangerous media
such as acetylene, ammable gases or liquids and toxic gases or liquids and
with refrigeration plants or compressors). If you do not observe the appropriate
regulations, serious injuries and/or damage can occur!
■
Open pressure connections only after the system is without pressure!
■
Please make sure that the pressure transmitter is only used within the overload
threshold limit all the time!
■
Observe the ambient and working conditions outlined in section 6 table „Speci-
cations”.
■
Ensure that the pressure transmitter is only operated in accordance with the
provisions i.e. as described in the instructions.
■
Do not interfere with or change the pressure transmitter in any other way than
described in these operating instructions.
■
Remove the pressure transmitter from service and mark it to prevent it from
being used again accidentally, if it becomes damaged or unsafe for operation.
■
Take precautions with regard to remaining media in removed pressure transmit-
ter. Remaining media in the pressure port may be hazardous or toxic!
■
Have repairs performed by the manufacturer only.

WARNING
Consider the details given in the EC-type examination certicate and specic
conditions of use as well as the respective country specic regulations for installa-
tion and operation in hazardous areas (e.g.: IEC 60079-14). If you do not observe
these stipulations, serious injuries and/or damage can occur.
5. Packaging
Has everything been supplied?
Check the scope of supply:
■
Completely assembled pressure transmitters; with ush version E-11 including
pre-assembled sealings and plastic protection cap.
■
Inspect the pressure transmitter for possible damage during transportation.
Should there be any obvious damage, inform the transport company and WIKA
without delay.
■
Keep the packaging, as it oers optimal protection during transportation (e.g.
changing installation location, shipment for repair).
■
Ensure that the pressure connection thread and the connection contacts will
not be damaged.

6. Starting, operation
6.1 Diaphragm test for your safety
Required tools: wrench (ats 27), screw driver
It is necessary that before starting the pressure transmitter you test the diaphragm, as this is a
safety-relevant component.
WARNING
■
Pay attention to any liquid leaking out, for this points to a diaphragm damage.
■
Check the diaphragm visually for any damage (E-11).
■
Use the pressure transmitter only if the diaphragm is undamaged.
■
Use the pressure transmitter only if it is in a faultless condition as far as the
safety-relevant features are concerned (e.g. no damage of case, cable and
connection threads. Otherwise explosion protection is not ensured).
In order to protect the diaphragm, the pressure connection of the instrument E-11 is provided
with a special plastic protection cap.
■
Remove this plastic protection cap only just before installing the pressure trans-
mitter in order to prevent any damage to the diaphragm or the thread.
■
Keep the plastic protection cap of the pressure connection thread and the
diaphragm for later storage or transport.
■
Mount the plastic protection cap when removing and transporting the instru-
ment.
