3.2 Principle of operation
IPT-1* Vers. 2.0 is a pressure transmitter for use in the paper, food
processing and pharmaceutical industries as well as in water/sewage
water plants. Depending on the version, it is used for level, gauge,
absolute pressure or vacuum measurement. Measured products are
gases, vapours and liquids, also those containing abrasive sub-
stances.
Thesensorelementisameasuringcellwithrobust,front-ush
(dependingontheprocesstting),abrasion-resistantceramicdia-
phragm.The process pressure causes a capacitance change in the
measuring cell via the ceramic diaphragm.This change is converted
into an appropriate output signal and outputted as measured value.
The measuring cell is also equipped with a temperature sensor. The
temperature value can be displayed via the display and adjustment
module as well as processed via the signal output (with digital ver-
sions).
As a standard feature, the ceramic measuring cell is equipped with a
lateral, recessed seal.
Instruments with double seal have an additional front seal.
Instrumentswithhygienicttingareequippedwithagap-freeform
seal.

3.3 Adjustment
The instrument can be adjusted with the following adjustment media:
• With the display and adjustment module
3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transportpackaging.Nonobservanceoftheseinstructionscancause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Uptothetimeofinstallation,thepackagesmustbeleftclosedand
stored according to the orientation and storage markings on the
outside.
Unlessotherwiseindicated,thepackagesmustbestoredonlyunder
the following conditions:

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
Inhazardousareasyoumusttakenoteoftherespectiveregulations,
conformityandtypeapprovalcerticatesofthesensorsandpower
supply units.
Power supply and current signal are transmitted via the same two-
wireconnectioncable.Thesupplyvoltagerangecandierdepending
ontheinstrumentversion.Theexactrangeisstatedinthe"Technical
data"inthe"Supplement".
Provide a reliable separation between the supply circuit and the
mainscircuitsaccordingtoDINEN61140VDE0140-1.
Keepinmindthefollowingadditionalfactorsthatinuencetheoperat-
ing voltage:
• Output voltage of the power supply unit can be lower under nomi-
nal load (with a sensor current of 20.5 mA or 22 mA in case of fault
message)
• Inuenceofadditionalinstrumentsinthecircuit(seeloadvaluesin
chapter"Technical data")
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
testvaluesofEN61326forindustrialareas,screenedcableshould
be used.
Usecablewithroundcross-section.Acableouterdiameterof
5…9mm(0.2…0.35in)ensuresthesealeectofthecablegland.
Ifyouareusingcablewithadierentdiameterorcross-section,
exchange the seal or use a suitable cable gland.
If screened cable is necessary, connect 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 potential equalisa-
tion (low impedance).
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V).The low-frequency potential equalisation currents are thus
suppressed,buttheprotectiveeectagainsthighfrequencyinterfer-
ence signals remains.

connected to ground potential only on one end (inside the switch-
ing cabinet) in such applications.The cable screen must not be
connected to the internal ground terminal in the sensor and the outer
ground terminal on the housing not to potential equalisation!
Information:
The metallic parts of the instrument such as transmitter and process
ttingareconductivelyconnectedwiththeinnerandouterground
terminal on the housing.This connection exists either as a direct me-
tallic contact or via the shielding of the special connection cable on
instrumentswithexternalelectronics.Youcanndspecicationson

data".
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents

can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2 Connection procedure
Proceed as follows:
1. Unscrewthehousingcover
2. If a display and adjustment module is installed, remove it by turn-
ing it to the left.
3. Loosen compression nut of the cable entry
4. Removeapprox.10cmofthecablemantle,stripapprox.1cm
insulation from the individual wires
5. Insert the cable into the sensor through the cable entry
6. Lift the opening levers of the terminals with a screwdriver (see
following illustration)
7. Insert the wire ends into the open terminals according to the wir-
ing plan
8. Press down the opening levers of the terminals, you will hear the
terminal spring closing
9. Check the hold of the wires in the terminals by lightly pulling on
them
10. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
11. Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable
