been designed and manufactured using state-of-the-art technol-
ogy. All components are subject to stringent quality and environ-
mental criteria during production. Our management systems are
certied to ISO 9001 and ISO 14001.
These operating instructions contain important information on
handling the instrument. Working safely requires that all safety
instructions and work instructions are observed.
Observe the relevant local accident prevention regulations and
general safety regulations for the instrument’s range of use.
The operating instructions are part of the product and must be
kept in the immediate vicinity of the instrument and readily acces-
sible to skilled personnel at any time. Pass the operating instruc-
tions on to the next operator or owner of the instrument.
Skilled personnel must have carefully read and understood the
operating instructions prior to beginning any work.
The general terms and conditions contained in the sales
documentation shall apply.

2. Design and function
2.1 Description
The model PG43SA-S and PG43SA-C pressure gauges are
designed especially for the requirements of the food and beverage,
pharmaceutical and biotechnology industries.
The pressure gauge is particularly suitable for the special conditions
of CIP/SIP cleaning processes, such as 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.
2.2 Scope of delivery
Cross-check scope of delivery with delivery note.

3. Safety
3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can
result in serious injury or death, if not avoided.
Information
... points out useful tips, recommendations and
information for ecient and trouble-free operation.
3.2 Intended use
The model PG43SA-S and PG43SA-C pressure gauges are 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.
3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous
situations and injuries.
▶Refrain from unauthorised modications to the
instrument.
Any use beyond or dierent to the intended use is considered as
improper use.

3.4 Personnel qualification
WARNING!
Risk of injury should qualication be insucient
Improper handling can result in considerable injury and
damage to equipment.
▶The activities described in these operating instruc-
tions may only be carried out by skilled personnel
who have the qualications described below.
Skilled personnel
Skilled personnel, authorised by the operator, 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 regulations, current standards
and directives, are capable of carrying out the work described and
independently recognising potential hazards.
4. Transport, packaging and storage
4.1 Transport
Check the measuring instrument for any damage that may have been
caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to
property can occur.
▶When unloading packed goods upon delivery as well
as during internal transport, proceed carefully and
observe the symbols on the packaging.
▶With internal transport, observe the instructions in
chapter 4.2 “Packaging and storage”.

4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging, especially the diaphragm protection (if avail-
able).This will provide optimum protection during transport (e.g.
cleaning, change in installation site, sending for repair).
CAUTION!
Damage to the diaphragm during unpacking
With improper unpacking, a high level of damage to
property can occur.
Avoid touching the diaphragm after removing the
diaphragm protection. Impermissible mechanical loading
(e.g. pressing the diaphragm) can result in measuring
deviations or even in the complete failure of the measur-
ing instrument.
The PG43SA-C is optionally packed under sterile
conditions, and on the perforation on the rear of the
sterile packaging there is a brown-coloured process
indicator. By checking this brown colouration you can
nd out whether the gauge has been packed under
sterile conditions.
Store instruments that are packed under sterile
conditions in the instrument package (no condensation
allowed, storing possible for 6 months).
Permissible conditions at the place of storage
Storage temperature: -20 ... +70 °C
Protect the pressure gauge from dust.

5. Commissioning, operation
5.1 Mounting preparation
To protect the pressure gauge from mechanical damage keep it in
the outer carton until installation.
The gauge should only be removed form the sterile packaging
shortly before mounting at the measuring point.
With CIP (cleaning in place) we recommend to clean the pressure
gauge again after mounting, using the process established at the
operator's site.
With COP (cleaning out of place) we recommend to clean the
pressure gauge again before mounting, using the process estab-
lished at the operator's site.
On removal from the packaging, and during mounting, particular
care must be taken to avoid damage and any mechanical defor-
mation to the diaphragm.
5.2 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.

EN
WIKA operating instructions pressure gauge, PG43SA-S, PG43SA-C
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.
The vent hole at the underside of the case must not be closed
(only applies to model PG43SA-S).
Nominal position per EN 837-3 / 9.6.6 gure 7: 90° ( ⊥) (only
applies to model PG43SA-S)
5.3 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 indica-
tion accuracy must be observed.
In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation.
5.4 Permissible vibration load at the installation site
The instruments should always be installed in locations free from
vibration.
5.5 Commissioning
During the commissioning process pressure surges must be avoided
at all costs.
