A metallic measuring cell is used as sensor element. The process
pressures are transmitted via the separating diaphragms and lling
oils to a resistance measuring bridge (semi-conductor technology).
The dierence between the acting pressures generates a change in
the bridge voltage. This change is measured, further processed and
converted into a corresponding output signal.
The markings "+" and "-" on the process component in chapter
"Mounting and connection instructions" must therefore be noted when
connecting to the process. The pressure acting on "+" goes positive,
the pressure acting on "-" goes negative into the calculation of the
pressure dierence.
The conguration of the measuring cells diers depending on the
measuring range:

4.1 General instructions to use the instrument
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
process tting, are suitable for the existing process conditions, such
as process pressure, process temperature as well as the chemical
properties of the medium.
You can nd the specications in chapter "Technical data" and on the
nameplate.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give the instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain o. This ap-
plies mainly to outdoor mounting as well as installation in areas where
high humidity is expected (e.g. through cleaning processes) or on
cooled or heated vessels.
The ventilation for the electronics housing is realised via a lter ele-
ment in the vicinity of the cable glands.

1 Filter element for ventilation of the electronics housing
2 Blind plug
Information:
Make sure that the lter element is always free of buildup during
operation. A high-pressure cleaner may not be used for cleaning.
DP ow elements are calculated for certain pipeline and operating
data. Therefore, check the pipeline data before installation at the
measuring point and compare the measurement loop number.
Detailed instructions for mounting the DP ow element are stated in
DIN EN ISO 5167 as well as in the instrument documentation from the
respective manufacturer.
You will nd general recommendations for the installation of eective
pressure lines in the corresponding national or international stand-
ards. When installing eective pressure lines outdoors, consider
applying suitable anti-freeze protection, e.g. tube heating. Install
eective pressure lines with a monotonic downward slope of at least
10 %.

WIKA Operating Instructions - Dierential pressure transmitter DPT-10
In case of strong vibrations at the application position, the instrument
version with external electronics should be used.
Higher process temperatures often mean also higher ambient tem-
peratures for electronics and connection cable. Make sure that the
upper temperature limits stated in chapter "Technical data" for the
environment of the electronics housing and connection cable are not
exceeded.
4.2 Instructions for oxygen applications
Oxygen and other gases can be explosive when brought into contact
with oils, grease and plastics, so the following measures must also be
taken:
• All components of the plant, such as e.g. measuring instru-
ments must be cleaned according to the requirements of BAM
(DIN 19247)
• Depending on the seal material, certain temperatures and pres-
sures must not be exceeded in oxygen applications, see chapter
"Technical data"
Danger:
Instruments for oxygen applications must be unpacked just before
mounting. After removing the protective cover of the process tting,
the label "O2" will be visible on the process tting. Penetration of oil,
grease and dirt should be avoided. Danger of explosion!
4.3 Mounting and connection instructions
When connecting the DPT-10 to the measurement loop, take note
of the plus/minus side of the process component. The plus side is
marked with a "+", the minus side with a "-" on the process compo-
nent next to the oval anges.

Valve blocks enable the simple installation and setup of the dierential
pressure transmitter. They separate the pressure transmitter from the
process side and enable also a check of the measurement loop. They
are available as 3-fold and 5-fold version. The integrated equalization
valve enables a pressure compensation between plus and minus side
during the setup. Thanks to the valve block it is possible to dismount
the DPT-10 without interrupting the process. This means higher plant
availability and simpler setup or maintenance.
The 3-fold valve block with anging on both sides enables a mechani-
cally stable connection between the DPT-10 and e.g. the tapping
points or the ange plate of a pitot tube. With the ve-fold valve block,
two additional valves allow blowing out the process lines or checking
the DPT-10 in installed condition.
