throughdierentcableandtubeversionsallowstheinstrumenttobe
usedinmanydierentapplications.
Measured products are liquids.
Depending on the instrument version and measurement setuo, meas-
ured products can be also viscous or contain abrasive substances.
Sensor element is the CERTEC®measuring cell with robust ceramic
diaphragm.Theprocesspressuredeectstheceramicdiaphragm
and causes a capacitance change in the measuring cell. This capaci-
tance change is converted into an electrical signal and outputted as
measured value via the output signal.
The CERTEC®measuring cell has also an integrated temperature
sensor. The temperature value is outputted through:
• The display and adjustment module
• The current output
• The digital signal output
The measuring cell design depends on the selected pressure type.
Relative pressure: the measuring cell is open to atmosphere.The
ambient pressure is detected in the measuring cell and compensated.
Itthushasnoinuenceonthemeasuredvalue.
Absolute pressure: the measuring cell is evacuated and encapsu-
lated. The ambient pressure is not compensated and does hence
inuencethemeasuredvalue.
Relative pressure, climate-compensated: the measuring cell is
evacuated and encapsulated. The ambient pressure is detected
through a reference sensor in the electronics and compensated. It
thushasnoinuenceonthemeasuredvalue.
The following illustration shows the installation of the CERTEC®
measuring cell in the transmitter as well as the sealing concept.

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
• If overvoltage surges are expected, overvoltage arresters should
be installed
Power supply and current signal are carried on the same two-wire
cable.Theoperatingvoltagecandierdependingontheinstrument
version.
Thedataforpowersupplyarespeciedinchapter"Technical data".
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN EN 61140 VDE 0140-1.
Keepinmindthefollowingadditionalfactorsthatinuencetheoperat-
ing voltage:
• Lower output voltage of the power supply unit under nominal load
(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault
message)
• Inuenceofadditionalinstrumentsinthecircuit(seeloadvaluesin
chapter "Technical data")
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326-1 for industrial areas, screened cable should
be used.
Use cable with round cross section for instruments with housing and
cablegland.Toensurethesealeectofthecablegland(IPprotection
rating),ndoutwhichcableouterdiameterthecableglandissuitable
for.
• 5 … 9 mm (0.20 … 0.35 in)
• 6 … 12 mm (0.24 … 0.47 in)
• 10 … 14 mm (0.40 … 0.55 in)
Useacableglandttingthecablediameter.
With plastic housing, the NPT cable gland or the Conduit steel tube
must be screwed without grease into the threaded insert.
Max. torque for all housings see chapter "Technical data".
If screened cable is required, we recommend connecting the cable
screen on both ends to ground potential. In the sensor, the screen
must be connected directly to the internal ground terminal.The
ground terminal on the outside of the housing must be connected to
the ground potential (low impedance).
With Ex systems it must be ensured that the grounding corresponds
to the installation regulations.
In electroplating and CCP systems (cathodic corrosion protection) it
mustbetakenintoaccountthatsignicantpotentialdierencesexist.
