1. General information
1.1 Information on the operating manual
This operating manual contains important information on
proper usage of the device. Read this operating manual
carefully before installing and starting up the pressure
measuring device.
Adhere to the safety notes and operating instructions which
are given in the operating manual. Additionally applicable
regulations regarding occupational safety, accident preven-
tion as well as national installation standards and engineer-
ing rules must be complied with!
This operating manual is part of the device, must be kept

1.3 Target group
WARNING! To avoid operator hazards and damages of
the device, the following instructions have to be worked
out by qualified technical personnel.
1.4 Limitation of liability
By non-observance of the operating manual, inappropriate
use, modification or damage, no liability is assumed and
warranty claims will be excluded.
The conformity of the produced end device has to be en-
sured by the responsible design engineer or developer.
1.5 Intended use
- The pressure transmitter EP 500 has been designed for
hard conditions especially in shipbuilding and offshore
applications. The EP 500 is intended, depending on the
ordered pressure range, for the pressure measurement
of gauge or absolute pressure. A
typical application is
e.g. level measurement via air bubbling. The EP 500 ful-
fil the requirements of Germanischer Lloyd (GL) as
standard. The certificate is available for download on
our
homepage:
http://www.bdsensors.com/proucts/
download/certificates
- It is the operator's responsibility to check and verify the
suitability of the device for the intended application. If
any doubts remain, please contact our sales department
in order to ensure proper usage. BD SENSORS is not
liable for any incorrect selections and their effects!
- Permissible media are gases or liquids, which are com-
patible with the media, wetted parts of the device.
- The technical data listed in the current data sheet are
engaging and must be complied with. If the data sheet is
not available, please order or download it from our
homepage: http://www.bdsensors.com/products/down-
load/datasheets
WARNING!
Danger through improper usage!
1.6 Package contents
Please verify that all listed parts are undamaged included in
the delivery and check for consistency specified in your
order:
- pressure transmitter EP 500
- mounting instructions
2. Product identification
The device can be identified by its manufacturing label. It
provides the most important data. By the ordering code the
product can be clearly identified.

The manufacturing label must not be removed from the
device!
3. Mechanical installation
3.1 Mounting and safety instructions
WARNING! Install the device only when depressurized
and currentless!
WARNING! This device may only be installed by
qualified technical personnel who has read and under-
stood the operating manual!
!
Handle
this
high-sensitive
electronic
precision
measuring device with care, both in packed and
unpacked condition!
!
There are no modifications/changes to be made on the
device.
!
Do not throw the package/device!
!
To avoid damaging the diaphragm, remove packaging
and protective cap directly before starting assembly.
The delivered protective cap has to be stored!
!
Place the protective cap on the pressure port again
immediately after disassembling.
!
Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.
!
Do not use any force when installing the device to
prevent damage of the device and the plant!
!
For the installation following points have to be ob-
served:
- By factory, the device has an ingress protection of
IP 00. Therefore the mounting / installation has to
be performed carefully. Additionally the device has
to be protected from the environmental effects by
the installation in a ventilated housing, with a much
higher ingress protection than the device. Check, if
the desired ingress protection is sufficiently for
your application. (recommendation: IP 65 at least)
- Install the device in such a way that it is protected
from direct solar irradiation. Direct solar irradiation
can lead to the permissible operating temperature
being overstepped in the worst case. Through this,
the operability of the device can be affected or
damaged. If the internal pressure increases due to
solar irradiation, temporary measurement errors
may occur.
- Install the device in such a way, that the gauge
reference, which is necessary for measuring, is
protected from dirt and moisture.
- Take note that no assembly stress occurs at the
pressure port, since this may cause a shifting of
the characteristic curve.
Provide a cooling line when using the device in steam
piping.
If there is any danger of damage by lightning or
overpressure when the device is installed outdoor, we
suggest putting a sufficiently dimensioned overpressure
protection between the supply or switch cabinet and the
device.
3.2 General installation steps
- Carefully remove the pressure measuring device from
the package and dispose of the package properly.
- Go ahead as detailed in the specific instructions below.
3.3 Installation steps for tube nozzle
- Slip your flexible tubes (
∅
4 mm) onto the tube nozzles
as far as possible.
3.4 Installation steps for G 1/4" acc. to EN 837
- Use a suitable seal, corresponding to the medium and
the pressure input (e. g. a cooper gasket).
- Ensure that the sealing surface of the taking part is
perfectly smooth and clean.
- Screw the device into the corresponding thread by
hand.
- Tighten it with a wrench (approx. 20 Nm).
