4. Design and function / 5. Electrical switch contacts
4. Design and function
Description
Bourdon tube measuring elements are widely used in technical pressure
measurement due to their robustness and ease-of-use. Under the inuence
of pressure, these measuring elements deform within their elastic limits.
This motion is converted, via a mechanical movement (toothed gear), into
a rotational motion.To this, an electrical limit switch is connected - the
magnetic snap-action contact.The contact closes or opens the connected
electrical circuits when the settable limit values are exceeded.
Scope of delivery
Cross-check scope of delivery with delivery note.
5. Electrical switch contacts
Electrical connection
The electrical connection must only be made by qualied skilled
personnel
Connection of the switches via cable or via screw terminals in the
terminal box (L-connector)
The terminal assignment is stated on the product label of the pressure
gauge
The gauges must be connected to the equipotential bonding of the plant
Electromagnetic compatibility
EMC per EN 60947-5-2.
The instruments are to be protected against strong electromagnetic elds.

Magnetic snap-action contact (normally closed or normally open)
The instruments are delivered with a single or double contact (normally
closed or normally open).
With 'normally closed', the contact ag is engaged with the limit switch and,
on rising pressure, disengages from the contact via the actuator attached to
the pointer.The circuit will be interrupted.
With 'normally open' the contact ag follows the pointer until the limit value
is reached. Once the limit value has been exceeded, the contact ag
engages and the circuit is closed.
The switching function of the switch is indicated by the index 1, 2, 12, 11
or 22.

Switch point adjustment (model PGS10 and PGS11)
To adjust the switch point, carefully loosen the window using a screwdriver.
The contact (red mark pointer) can then be set to the desired position by
hand. It can be set between 10 % and 90 % of the full scale value.
Afterwards, lightly push the window back into the case.
6. Transport, packaging and storage
6.1 Transport
Check pressure gauge for any damage that may have been caused by
transport.
Obvious damage must be reported immediately.
6.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport
(e.g. change in installation site, sending for repair).
6.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +70 °C

7. Commissioning, operation
Mechanical connection
In accordance with the general technical regulations for pressure gauges
(e.g. EN 837-2 "Selection and installation recommendations for pressure
gauges").
If the pressure gauge is mounted lower than the pressure tapping, the
capillary must be ushed thoroughly before connection in order to clear out
any foreign matter.
When screwing gauges in, the force required for this must not be applied
through the case, but rather through the spanner ats (using a suitable tool)
provided for this purpose on the square shaft of standard connections.
7. Commissioning, operation
Installation with
spanner
Correct sealing of pressure gauge connections with parallel threads  must
be made using suitable sealing rings, sealing washers or WIKA prole seals.
The sealing of tapered threads (e.g. NPT threads) is made by providing the
thread
 , with additional sealing material such as, for example, PTFE tape
(EN 837-2).
The torque depends on the seal used. Connecting the gauge using a clamp
socket or a union nut is recommended, so that it is easier to orientate the
gauge correctly.

Requirements for the installation point
If the measuring point is not adequately stable a measuring instrument
support such as a bracket or ange should be used for fastening (and
possibly via a exible capillary line). If the pressure gauge is exposed to
vibration or pulsating pressure or both, then a liquid lled pressure gauge
may provide considerably better performance and readability. Instruments
should be protected against coarse dirt and wide uctuations in ambient
temperature.
Installation
Nominal position per EN 837-1 / 9.6.7 Figure 9: 90° ( ⊥ )
Process connection bottom or rear!
In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!
Measuring assemblies
Proven measuring assemblies for various types of media.
7. Commissioning, operation
Admissible ambient and working temperatures
When mounting the pressure gauge it must be ensured that, taking into
consideration the inuence of convection and heat radiation, no deviation
above or below the permissible ambient and medium temperatures can
occur. The inuence of temperature on the display accuracy must be
observed.

Permissible vibration load at the installation site
The instruments should always be installed in locations free from
vibration.
If the pipe to the gauge is not rigid enough for a vibration-free
installation, the gauge should be mounted by means of mounting
devices for surface or pipe mounting, and, if necessary, with a capillary.
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:
Frequency range < 150 Hz
Acceleration < 0.5 g (5 m/s2)
Commissioning
During the commissioning process pressure surges must be avoided at all
costs. Open the shut-o valves slowly.
8. Maintenance and cleaning
8.1 Maintenance
The instruments are maintenance-free.
The indicator and switching function should be checked once or twice
every year.The gauge must be disconnected from the process to check
with a pressure testing device.
Repairs are only to be carried out by the manufacturer or appropriately
trained skilled personnel.

8.2 Cleaning
CAUTION!
■ Before cleaning, correctly disconnect the pressure gauge
from the pressure supply, switch it o and disconnect it
from the mains.
■ Clean the pressure gauge with a moist cloth.
■ Electrical connections must not come into contact with
moisture.
■ Wash or clean the dismounted pressure gauge
before returning it, in order to protect persons and the
environment from exposure to residual media.
9. Dismounting and disposal
WARNING!
Residual media in dismounted pressure gauges may result
in a risk to people, the environment and the system.Take
sucient precautionary measures.
9.1 Dismounting
Only disconnect the pressure gauge once the system has been depres-
surised!
9.2 Disposal
Incorrect disposal may endanger the environment.
Dispose of instrument components and packaging materials in an environ-
mentally compatible way and in accordance with the country-specic waste
disposal regulations.
