1. Safety instructions / 2. Operating principle
1. Safety instructions
GB
Serious injuries and/or damage can occur should the appropriate
regulations not be observed.
Only appropriately qualified personnel should work on these instru-
ments.
The appropriate national safety regulations (e.g. EN 837-2
"Selection and installation recommendations for pressure
gauges") must be observed when installing, commissioning
and operating these devices.
2. Operating principle
Bourdon tube, diaphragm and capsule measuring elements are widely used as
measuring elements for such transmitters thanks to their robustness and easeof-use within technical pressure measurement. Under the influence of pressure,
these measuring elements will be deformed within their elastic range.
This movement is converted into a rotary motion by means of a mechanical
movement (gear). A magnet, fixed to the pointer axle, turns with the instrument‘s pointer, in direct proportion to the process pressure. The connected
electronics detect the rotary motion of the magnet between 0 and 270 degrees.
A non-contact (and thus wear-reseistant), magnetic-field dependant sensor
(angular rotation sensor, 10 bit resolution) measures the change electrically.
An amplifier converts the rotary motion into an electrical output signal. The
electronics are factory set to a standard passive 4 ... 20 mA output signal,
(0 ... 20 mA, 0 ... 10 V and 4 ... 20 mA ATEX versions are available as options).
The electrical output signal range corresponds to the measuring range on the
dial.
With these three standard electrical output signals, this series of instruments
can be used in all areas of industry.
A pressure gauge with an intelliGAUGE series transmitter combines all the
advantages of an on-site mechanical display with the demands modern industry makes for electrical signal transmission for the acquisition of measured
values.

4. Installation instructions
4. Installation instructions
The pressure gauge must be installed in a shock-free way and positioned in
GB
order to be clearly visible. We recommend connecting an interlocking device
between the pressure tapping point and the pressure gauge, enabling the
measuring device to be changed and to allow the zero point to be checked with
the plant still running.
Installation
Nominal position in accordance with EN 837-3 / 9.6.6 fig 7: 90° (⊥)
Bottom entry pressure connection
There must be a free space of at least 25 mm behind the housing to allow
the pressure to be safely and reliably vented through the rear wall in the
event of a fault!
To avoid supplementary heating, the instruments must not be exposed to
direct sunlight during operation!
With filled variants, open the vent valve (with pressure ranges ≤ 10 bar) on
the top of the housing before commissioning!
Permissible vibration load at the mounting point
The instruments should always be installed in locations free from vibration.
If necessary, it is possible to isolate the instrument from the mounting point
by installing a flexible connection line between the measuring point and the
pressure gauge and mounting the instrument on a suitable bracket.
If this is not possible, the following limit values must not be exceeded:
Unfilled devices: Frequency range < 150 Hz
Acceleration < 0.7 g (7 m/s²)
Liquid filled devices: Frequency range < 150 Hz
Acceleration < 4 g (40 m/s²)
Check the liquid filling at regular intervals.
The liquid level must not drop below 75 % of the instrument‘s diameter.
Test connector
Local safety codes such as those for pressure or steam vessels may specify
isolating devices to enable on-site testing of the pressure instrument.

WIKA Operating Instructions intelliGAUGE family
11297264 05/2009 GB/D/F/E
4. Installation instructions
Mounting provisions
If the line for the pressure gauge is not rigid enough for vibration-free installation, fasten the instrument using appropriate fastening elements for wall and/or
pipe mounting, and, if necessary, by means of a capillary line.
Measuring system damping
If it is not possible to avoid vibration by means of appropriate mounting, use
pressure gauges with liquid filling.
Effects of temperature
The operating temperature of the pressure instrument, resulting from the effects
of radiated heat, must not exceed the temperature range the pressure instrument is intended for. Suitably-shaped tailpipes or syphons with water filling may
be used to separate the pressure transmitter and its isolating device from hot
pressure media.
The effective maximum surface temperature is not dependant
upon the device, but mainly on the temperature of the respective pressure medium! In the case of gaseous substances, the
temperature may increase due to compression warming. In
these cases it may be necessary to throttle the rate of change
of pressure or reduce the permissible temperature of the
pressure medium.
GB
Diaphragm seal/separating foil
In the case of aggressive, hot, highly viscous, contaminated or crystallising
pressure media, which must not be allowed to enter the measuring element,
diaphragm seals must be used as a separating barrier. A neutral transmission fluid, used to transmit the pressure to the measuring element, should be
selected with consideration to the measuring range, the temperature and its
compatibility with the pressure media.
Under no circumstances must the connection between the pressure gauge and
the diaphragm seal be loosened.
Protection of the measuring element against overload
If the pressure media is subject to rapid pressure changes, or pressure impulses may be expected, these must not act directly on the measuring element. The
effect of the pressure impulses must be damped, e.g. by installing an integrated
restrictor screw (reduction of the cross-section in the pressure channel) or by
connecting an adjustable throttle device in series.
11297264 05/2009 GB/D/F/E
WIKA Operating Instructions intelliGAUGE family 11
4. Installation instructions / 5. Installation and commissioning
Pressure test connection
The pressure test connection, with a sufficiently large bore (≥ 6 mm diameter),
should be arranged, as far as possible, over a shut-off device, in a position
GB
where the accuracy of the reading will not be affected by the flow of the media
being measured.
The piping between the pressure test connection and the pressure instrument
should have an inner diameter large enough to avoid blockages or delays in
pressure transmission.
Also, it should not have any sharp bends. It is recom-
mended that it is mounted with a continuous incline of approx. 1:15.
Piping
The piping should be arranged and fitted so that it can withstand the stresses
caused by expansion, vibration and the influence of heat. When the media is
gaseous, a water drain point should be provided at the lowest point. For liquid
pressure media, an air bleed should be provided at the highest point.
5. Installation and commissioning
The correct sealing of pressure connections should be achieved by means of
suitable sealing rings, sealing washers or WIKA profile seals.
We recommend connection by means of a union nut or a LH-RH adjusting nut
in order to simplify correct orientation of the gauge. When mounting them or
removing them, the pressure gauges must not be tightened using the housing,
but only on the spanner flats on the stem!
Installation using
a spanner
If the pressure transmitter is positioned lower than the pressure test connection, the tailpipe should be thoroughly cleaned prior to fitting the transmitter.
For technical reasons, it is necessary to ventilate liquid-filled pressure gauges
after installation. See the relevant label on the pressure gauge.
WIKA Operating Instructions intelliGAUGE family12
11297264 05/2009 GB/D/F/E
5. Installation and commissioning ... 6. Measuring arrangements
Once the pressure and electrical connections have been made, the transmitters
are ready for immediate use.
The A-VA-1 type or KFA6-STR-1.24.500 type feed units may be used to provide
the standard transmitter with DC voltage.
No attempt should be made to remove a pressurised instrument. If the transmitter cannot be otherwise isolated, the pressure system must be fully vented.
The clamping screws on the top and bottom flanges of diaphragm element
pressure gauges must not be unscrewed.
Any residual pressure medium contained in the pressure
element may be hazardous or toxic. This should be taken into
account when handling and storing pressure gauges which
have been removed.
Pressure connection
In accordance with the general technical regulations for pressure gauges (e.g.
EN 837-2 "Selection and installation recommendations for pressure gauges").

9. Service and maintenance
9. Service and maintenance
Always open isolating devices gently, never abruptly, since this may generate
sudden pressure surges that may damage the gauge. The maximum working
pressure for pressure gauges with transmitters is indicated by the limit marks
on the dial.
With fluctuating pressure loads, lower values apply in accordance with EN 837.
The pressure gauges with transmitters require no maintenance and feature a
long service life if handled and operated properly. As a result of the mechanical
loading, and depending on the service conditions, it may become necessary to
check and readjust the zero point of the transmitter.
Zero point test
Normally the zero point is checked and adjusted in an unpressurised state. The
zero point of differential pressure gauges with transmitters should be checked
and adjusted by opening the pressure compensating valve under static load.
Mechanical zero point (pointer)
If the pointer deviates from the zero point (in the unpres-
1)
Slotted
screw
surised condition), the zero point may be corrected by
means of the integrated adjustable pointer. To do this,
remove the bayonet ring, including the window and seal,
from the housing. The zero point is altered by turning the
adjusting screw on the adjustable pointer.
After correcting the zero point, fasten the bayonet ring
and the window with its seal and then close the pressure
compensating valve or open the stop valve.
GB
Electrical zero point (4 mA)
1)
If the mechanical zero point is changed by means of the adjustable pointer, the
electrical zero point must be reset to the mechanical zero point.
First depressurise the pressure gauge.
Loosen the complete cable hood on the right-hand side of the pressure gauge
by completely unscrewing the screw on the top of the cable hood cover
using an appropriate screwdriver (0.6 x 3.5 mm).

9. Service and maintenance
Extract the screw. Remove the cable hood
with the socket insert from the cable socket
base and thus separate the pressure gauge
GB
from the power supply.
Remove the cable hood cover from the
cable hood and push the socket insert
out downwards through the entire cable hood
.
Use a short stranded wire with bare points at
both ends (max. permissible resistance 30 Ω)
to bridge contacts 5 and 6 on the socket
insert.
Reassemble the plug in reverse order. Place
the plug, with the attached piece of stranded
wire, onto the pin insert , and thus reestablish the power supply.
Within a max. 30 seconds the new zero point
will be stored within the electronics. During
this period, the current in the loop will increase
to 9.5 mA.
The new zero point also remains stored in the
case of a power failure.
Loosen the plug again in the same sequence
as described above and remove the piece of
stranded wire. After reassembling the plug,
the electrical output signal will once more
correspond to the indication of the mechanical
pointer.

11. Storage
GB
Before installation, in order to prevent damage to the pressure instruments, the following points should be observed:
The pressure transmitter should be left in its original packing until installation.
After taking the transmitter out (e.g. for tests), reuse the original packaging
material.
The storage temperature should not be less than -40 °C or more than +70 °C.
Avoid the following influences:
Direct sunlight or vicinity to hot objects
Mechanical vibration
Soot, steam, dust, humidity and corrosive gasses
Potentially explosive environment, inflammable atmosphere
Before the system is stored, all traces of any medium residue
must be removed. This is particularly important if the medium
is a health hazard such as corrosive, toxic, carcinogenic,
radioactive, etc.
12. Maintenance and servicing/cleaning
The instruments require no maintenance or servicing and will give very long
service when handled and operated properly.
The indicator and switching function should be checked once or twice every 12
months. The instrument must be disconnected from the process before being
checked using pressure testing equipment.
The instruments should be cleaned with a damp cloth, moistened with soap
solution. Clean the instrument with a damp cloth. Particularly with regards to
ATEX model do not use a dry cloth for cleaning (electrostatic charging!)
Ensure that all parts are dry before the power is switched on again.

Betrieb dieser Geräte die entsprechenden nationalen Sicher-

Bei Nichtbeachten der entsprechenden Vorschriften können schwere
Körperverletzungen und/oder Sachschäden auftreten.

heitsvorschriften (z. B. EN 837-2 Auswahl- und Einbauempfehlungen für Druckmessgeräte).
2. Funktionsprinzip
Als Messelement für diesen Ferngeber werden die in der technischen Druckmesstechnik wegen ihrer Robustheit und einfachen Handhabung weit verbreiteten Rohr-, Platten-, Kapselfeder- und Wellrohrfedermessglieder verwendet.
Unter dem Einfluss eines Druckes verformen sich die Messglieder im
elastischen Bereich.
Diese Bewegung wird über ein mechanisches Messwerk (Zahnräder) in eine
Drehbewegung umgesetzt. Ein auf der Zeigerachse aufgesetzter Magnet dreht
sich proportional mit dem Instrumentenzeiger in direkter linearer Abhängigkeit
zum Prozessdruck. Die nachgeschaltete Elektronik erfasst die Drehbewegung
des Magneten im Bereich von 0 bis 270 Winkelgrade.
Ein magnetfeldabhängiger Sensor (Drehwinkelsensor, 10 bit Auflösung) greift
auf der elektrischen Seite diese Veränderung berührungslos ab und arbeitet
somit verschleißfrei.
Über einen Verstärker wird die Drehbewegung in ein elektrisches Ausgangssignal umgesetzt. Werkseitig ist die Elektronik auf das normierte Ausgangssignal
4 ... 20 mA passiv, eingestellt (0 ... 20 mA, 0 ... 10 V und 4 ... 20 mA ATEX-Version als Option verfügbar; nicht bei Typ PGT23.063). Die Spanne des elektrischen
Ausgangssignals entspricht der Messspanne auf dem Zifferblatt.
Durch die drei normierten elektrischen Ausgangssignale ist diese Gerätereihe in
allen Bereichen der Industrie einsetzbar.
Ein Druckmessgerät mit Ferngeber aus der intelliGAUGE-Reihe verbindet alle
Vorteile einer mechanischen Anzeige vor Ort mit der Forderung nach einer
elektrischen Signalübertragung für eine moderne Messwerterfassung in der
Industrie.
