3.2 Principle of operation
IPT-1* is a pressure transmitter for measurement of overpressure,
absolute pressure or vacuum. Measured products are gases, vapours
and liquids in measuring ranges up to 4000 bar (400 MPa); with front-
ushversionalsoviscousliquidsinmeasuringrangesupto600bar
(60 MPa).
The process pressure acts on the sensor element via the stainless
steel diaphragm and an internal transmission liquid.This causes a
resistance change which is converted into a corresponding output
signal and outputted as a measured value. With measuring ranges
up to 16 bar a pieoresistive sensor element is used, with measuring
ranges from 25 bar a strain gauge (DMS) sensor element.

ured value transmission on the same cable.
Thesupplyvoltagerangecandierdependingontheinstrumentver-
sion.Theexactrangeisstatedinchapter"Technical data".
The backlight of the display and adjustment module is powered by
the sensor. The prerequisite for this is a supply voltage at a certain
level.Theexactvoltagespecicationsarestatedinchapter"Technical
data".
3.3 Operation
The instrument can be adjusted with the following adjustment media:
• With the display and adjustment module
• the suitable WIKA DTM in conjunction with an adjustment software
according to the FDT/DTM standard, e.g. PACTware and PC
• Withmanufacturer-specicadjustmentprogramsAMS™orPDM
• With a HART handheld
The entered parameters are generally saved in IPT-1*, optionally also
in the display and adjustment module or in PACTware.
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.

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
In hazardous areas you must take note of the respective regulations,
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.
Keepinmindthefollowingadditionalinuencesontheoperating
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 required, 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.

is grounded on both ends. To avoid this, the cable screen must be
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 nottopotentialequalisation!
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
thepotentialconnectionswithintheinstrumentinchapter"Technical
data".
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents
owoverthecablescreen.Incaseofgroundingonbothsidesthis
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 slightly to the left.
3. Loosen compression nut of the cable entry gland
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of 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
