Use of the product in accordance with the intended use HP-1/HP-2:
Use the pressure transmitter to transform the pressure into an electrical signal in extremly
high pressure applications > 1000 bar.
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 specific application, you can obtain further information:
Via our Internet address www.wika.de / www.wika.com
The product data sheet is designated as PE 81.29 (HP-1) / PE 81.53 (HP-2)
Contact WIKA for additional technical support (+49) 9372 / 132-295
With special model number, e.g. HP-20000, please note specifications in the delivery note.
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 certified to DIN EN ISO 14001.
As the highly pressurised materials are subject to extreme loads a permanent load cycle stability is only given to a limited extent. This applies in particular to dynamic applications. According to this the pressurised parts of the HP-1 / HP-2 are wear parts which are not included in
the warranty.
Knowledge required: Install and start the pressure transmitter only if you are familiar with the
relevant regulations and directives of your country and if you have the qualification required.
You have to be acquainted with the rules and regulations on measurement and control technology and electric circuits, since this pressure transmitter is „electrical equipment“ as defined
by EN 50178. Depending on the operating conditions of your application you have to have the
corresponding knowledge, e.g. of aggressive media or high pressures.

The pressure prevailing within the application is transformed into a standardised electrical
signal through the deflection 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 evaluated correspondingly.
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.

Notice, important information, malfunction.
The product complies with
the applicable European
directives.
Select the appropriate pressure transmitter with regard to scale range,
performance and specific measurement conditions prior to installing and
starting the instrument.
Observe the relevant national regulations (e.g.: EN 50178) and observe the
applicable standards and directives for special applications. 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 7 „Technical data”.
Ensure that the pressure transmitter is only operated in accordance with the provisions i.e.
as described in the following 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 transmitter.
Remaining media in the pressure port may be hazardous or toxic!
Have repairs performed by the manufacturer only.
Please be aware of the fact that within a system under pressure the maximum pressure for
the complete system is determined by the component with the lowest admissible opera-
ting pressure, even when there are single components that can be operated with higher
pressures. When a wide range of pressures is expected within a measuring system, all
connected components must be able to withstand the highest possible pressure peaks.
Information about material consistency against corrosion and diffusion can be found in our
WIKA-Handbook, 'Pressure and Temperature Measurement'.
Potential danger of life or
of severe injuries due to
catapulting parts.
Potential danger of burns
due to hot surfaces.
2. A quick overview for you
If you want to get a quick overview, read Chapters 3, 5, 7 and 11. There you will get some
short safety instructions and important information on your product and its starting. Read
these chapters in any case.
Take appropriate protective measures to prevent parts from being ejected in
the case of faults. Ensure that these protective devices cannot be removed
without using tools.

Bei Sondertypennummer, z.B. HP-20000, beachten Sie die Spezifikationen gemäß Lieferschein. Wird die Seriennummer auf dem Typenschild und/oder der 2D-Code auf dem
Sechskant unleserlich (z. B. durch mechanische Beschädigung oder Übermalen), ist eine
Rückverfolgbarkeit nicht mehr möglich.
Die in der Betriebsanleitung beschriebenen WIKA-Druckmessgeräte werden nach den
neuesten Erkenntnissen konstruiert und gefertigt. Alle Komponenten unterliegen während der
Fertigung strengen Qualitäts- und Umweltkriterien. Unser Umweltmanagementsystem ist nach
DIN EN ISO 14001 zertifiziert.
Auf Grund der extremen Belastungen, denen die hochdruckbeaufschlagten Materialien ausgesetzt sind, ist eine Dauerlastwechselfestigkeit nur bedingt gegeben. Dies gilt insbesondere für
dynamische Anwendungen. Dementsprechend handelt es sich bei den druckbelasteten Teilen
des HP-1 / HP-2 um Verschleißteile, die nicht unter die Gewährleistung fallen.
Bestimmungsgemäße Produktverwendung HP-1/HP-2:
Verwenden Sie den Druckmessumformer, um in Hochdruck-Applikationen > 1000 bar den
Druck in ein elektrisches Signal zu wandeln.

4. Funktion
Mittels Sensorelement und unter Zuführung von Hilfsenergie wird über die Verformung einer
Membran der anstehende Druck in Ihrer Anwendung in ein verstärktes standardisiertes elektrisches Signal umgewandelt. Dieses elektrische Signal verändert sich proportional zum Druck
und kann entsprechend ausgewertet werden.
