2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate pressure gauge has been selected
in terms of measuring range, design and suitable wetted
material (corrosion) for the specic measuring conditions.
In order to guarantee the measuring accuracy and
long-term stability specied, the corresponding load
limits must be observed.
Non-observance can result in serious injury and/or
damage to the equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The model 432.55 pressure gauge is used for measuring pressure
particularly in sanitary applications.
The instrument has been designed and built solely for the intended
use described here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and
damage to equipment.
2. Safety

WIKA operating instructions pressure gauge, model 432.55 7
14055446.01 12/2012 GB/D/F/E
The activities described in these operating
instructions may only be carried out by skilled
personnel who have the qualications described
below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their
technical training, knowledge of measurement and control technology
and on their experience and knowledge of country-specic regula-
tions, current standards and directives, are capable of carrying out the
work described and independently recognising potential hazards.
2.3 Special hazards
WARNING!
For hazardous media such as acids, bases, amma-
ble or toxic gases or liquids, in addition to all standard
regulations, the appropriate existing codes or regulations
must also be followed.
WARNING!
Residual media in dismounted instruments can result in
a risk to persons, the environment and equipment.Take
sucient precautionary measures.

4. Design and function
4.1 Description
The model 432.55 pressure gauge is designed especially for the
requirements of the food and beverage, pharmaceutical and biotech-
nology industries.
The pressure gauge is particularly suitable for the special conditions of
CIP/SIP cleaning processes, e.g. thanks to chemical stability towards
cleaning liquids and high temperatures. The ush metal diaphragm
element is directly welded to the process connection.This guarantees
a crevice-free connection of process connection and diaphragm
element; additional internal sealings are not required.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.

5. Transport, packaging ... / 6. Commissioning ...
5. Transport, packaging and storage
5.1 Transport
Check the pressure gauge for any damage that may have been
caused by transport. Obvious damage must be reported immediately.
5.2 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).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +70 °C
Protect the pressure gauge from dust.
6. Commissioning, operation
The pressure gauge should be kept in its packing until installation.
The gauge should be protected from external damage during
storage.
On removal from the packaging, and during mounting, particular
care must be taken to avoid damage and any mechanical
deformation to the diaphragm.

Installation
Do not damage the diaphragm; scratches on the diaphragm (e.g.
from sharp-edged objects) are the main causes of corrosion.
For sealing, choose appropriate seals.
For ange mounting, only use sealings with a suciently large inner
diameter and centre them; contact with the diaphragm leads to
measuring errors.
When using soft or PTFE sealings, observe the instructions of the
sealing manufacturer, particularly with regard to tightening torque
and load cycles.
For installation, in accordance with the tting and ange standards
the appropriate fastenings, such as screws and nuts, must be used.
Permissible ambient and operating temperatures
When mounting the pressure gauge it must be ensured that, taking
into consideration the inuence of convection and heat radiation,
no deviation above or below the permissible ambient and medium
temperatures can occur. The inuence of temperature on the indication
accuracy must be observed.
In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!
Permissible vibration load at the installation site
The instruments should always be installed in locations free from
vibration.
Commissioning
During the commissioning process pressure surges must be avoided
at all costs.
