1. Safety / 2. Operating principle
1. Safety
The appropriate national safety regulations (e.g. EN 837-2
GB
„Selection and installation recommendations for pressure gauges“) must be ob-served when installing, commissio­ning and operating these devices.
Serious injuries and/or damage may occur should the appropriate regulations not be observed.
Only appropriately qualied personnel should work on these
instruments.
The eective 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.
2. Operating principle
Bourdon tubes are widely used as measuring elements for technical pressure measurement due to their robustness and ease-of-use. Under
the inuence of pressure these measuring elements will deform within their
elastic range.
This movement is converted into a rotary motion by means of a mechanical
movement (gear). A magnet, xed to the pointer axle, turns with the
instrument´s pointer in direct proportion to the process pressure. The electronics positioned facing the magnet detect the rotational motion of the magnet.
The electronics’ non-contact sensor element (Hall sensor), aected by the magnetic eld, detects any changes, free from any friction and wear to the
measuring element.
The sensor signal, which is in direct proportion to the angle of motion, is transformed into an output signal. The span of the electrical output signal corresponds to the measuring span of the dial.
An intelliGAUGE line pressure gauge with electrical output signal combines all the advantages of an on-site display without the need for an external power supply, with the demands of modern electronic measurement for electrical signal transmission.

3. Installation instructions
Installation
Nominal position acc. EN 873-3 / 9.6.6 gure 7: 0° or 90°
Pressure connector bottom or rearside
Permissible vibration load at the mounting point
The instrument should always be installed in locations free of vibration.
If necessary, it is possible to isolate the instrument from the mounting
point by installing a exible 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: Unlled devices: Frequency range 10 … 150 Hz
Accelaration < 0.5 g (5.0 m/s²) Liquid lled devices: Frequency range 10 … 150 Hz
Accelaration < 4.0 g (39.2 m/s²)
The liquid lling has to be checked periodically.
The liquid level must not drop below 75 % of the instrument´s diameter.
Test connector
At certain use cases (e.g. steam vessels) isolating devices have to have a test connector, so that the instrument can be checked without dismounting.
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 lling.
Eects of temperature
The mounting of the pressure instrument has to be done in a way that the operating temperature is neither exceeded nor falls below the permissible operating temperature, even in consideration of thermal convection and thermal radiation. Tailpipes of a suitable length or syphons may be used to protect the pressure instrument and the isolating device.
The inuence of the temperature onto the accuracy of indication and of
measurement has to be noticed.

3. Installation instructions / 4. Installation and ...
Diaphragm seal / protective barrier
In case of aggressive, hot, highly viscous, contaminated or crystallizing pressure media, which must not be allowed to intrude the measurign element, diaphragm seals have to be used as separating barrier. A neutral
GB
transmission uid, used to transmit the pressure to the measuring element,
should be selected in consideration of the measuring range, the tempera­ture and its compatibility with the pressure media. The connection between the pressure gauge and the diaphragm seal must not be released by no means.
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 upon the measuring
element. The eect of 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.
Pressure test connection
The pressure test connection, with a suciently large bore size (≥ 6 mm diameter), should be arranged, as far as possible, over a shut-o device, in a position where the accuracy of the reading will not be aected by the ow of the media being measured. The pipe 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 recommended that it is mounted with
a steep incline of approx. 1:15.
Piping
The piping should be arranged and tted so that it can withstand the stresses caused by expansion, vibration and the inuence 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.
4. Installation and commissioning
To acchieve a correct sealing of pressure connections suitable sealing
rings, sealing washers or WIKA prole seals have to be used. In order to get
the pressure instrument into an orientation that allows to read the on-site indicator the best, a connector with an adjusting nut or an union nut is recommended. When mounting and dismounting it is not allowed to tighten
the pressure instruments by using the housing, but on the spanner ats of
the stem, only.

4. Installation and commissioning / 5. Measuring arrangements
Installation using a spanner
If the pressure transmitter is positioned lower than the pressure test
connection, the tailpipe has to be rinsed thoroughly prior to tting the gauge
to remove all foreign substances. Once the pressure and electrical connections have been made, the trans-
mitter is ready for immediate use. Before dismounting the pressure instrument the measuring element has to
be depressurized. Eventually the stress of the pipe has to be relieved.
Residual pressure medium remaining within the pressure element may cause harm to men, facilities and environment.
Therefore sucient precautionary measures have to be
taken.

7. Servicing, Maintenance, Cleaning, Repairing / 8. Storage
7. Servicing, Maintenance, Cleaning, Repairing
Always open isolating devices gently, never abruptly, since this may generate sudden pressure surges that may damage the gauge.
Pressure instruments with an electrical output signal
require no maintenance and oer a long service life, if handled and
switch
operated properly. If the zero point drifts, it means that the instrument has been overloaded.
Clean the instrument with a moistened cloth. If badly soiled, moisten the cloth thoroughly with soapy water.
Repairs should be only be carried out by the manufacturer or by appropri-
ately trained sta.
8. Storage
Before the system is stored, all traces of any medium residue must be removed. This is particularly important,
if the media is a health hazard such as corrosive, toxic,
carcinogenic, radioactice, etc.
Before installation, in order to prevent damage to the pressure instrument, the following points should be observed:
The pressure instrument should be left in its original packaging until installation.
After taking the instrument out (e.g. for test), reuse the original packaging material.
The storage temperature should not be less than -40 °C or more than +90 °C
Avoid the following inuences:
Direct sunlight or vicinity to hot objects
Mechanical vibration
Sot, steam, dust, humidity and corrosive gasses
Potentially explosive environment, inammable atmospheres
