2. Design and function

2.1 Description

The model PG43SA-D diaphragm pressure gauge has been

designed specically for the highest safety requirements in the

pharmaceutical and biotechnology industries.Through its patent-

ed diaphragm monitoring, the risk of an undetected rupture of the

diaphragm is eliminated since a red warning dot is immediately

displayed on the dial.

In the event of a diaphragm rupture, a second barrier in the instru-

ment ensures the reliable separation of ambience and process.

The diaphragm pressure gauge transmits the pressure, purely

mechanically and without transmission uid, from the process to the

pressure element. Due to their thickness, the diaphragm elements

are very robust and have high overpressure safety, ensuring a safe

pressure measurement without any risk of contamination.

The ush welded diaphragm element in conjunction with the aseptic

process connections enables a dead-space free connection to the

process.

The PG43SA-D in hygienic design can be used for CIP (cleaning in

place) and SIP (sterilisation in place) and in wash-down areas, or it

can be completely sterilised in an autoclave. The measuring instru-

ment can thus be cleaned reliably and time-eciently. The model

PG43SA-D conforms to the 3-A Sanitary Standard and is certied in

accordance with EHEDG.

2.2 Integrated diaphragm monitoring

Second barrier

Diaphragm element

White: Diaphragm element intact

Status display

Red: Diaphragm element defective

If the status display shows the red warning dot, the measures in

chapter 6 “Faults” must be followed.

Function

The continuous diaphragm monitoring indicates the current state of

the pressure element.

A defective diaphragm element will be immediately indicated to the

user as a red warning dot on the dial (see picture). With the aid of the

status display, the integrity of the pressure element can be checked

both prior to installation and during operation.

Second barrier

The diaphragm element serves as the rst barrier between process

and ambience. A second barrier, located behind it, guarantees the

reliable separation of ambience and process, even in the event of

a rupture in the diaphragm element.The risk of any contamination

between ambience and process is eliminated by the second barrier.

2. Design and function

14198218.02 02/2018 EN/DE/FR/ES

WIKA operating instructions disphragm pressure gauge, model PG43SA-D

Reference chamber

The reference chamber is an evacuated pressure chamber behind

the diaphragm element and serves as a reference for the status

display of the diaphragm element.

In the event of a damaged diaphragm element

Vacuum in the reference chamber collapses

Reference chamber is pressurised with process pressure

Medium can ingress into the reference chamber

Colour of the status display changes to red.

Measuring instrument is defective and can no longer be used as a

reference for the process pressure.

Replace measuring instrument.The dismounting of the measuring

instrument is described in chapter 8.

Despite a damaged diaphragm element, due to the second barrier

no exchange has occurred between process and ambience

2.3 Scope of delivery

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 ecient and trouble-free operation.

3.2 Intended use

The model PG43SA-D diaphragm 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.

Operating limits of the status display

The status display of the diaphragm monitoring requires process

pressures ≥ 250 mbar abs.

The status display has been conceived for use up to a height of

max. 2,000 m above sea level.

3.3 Improper use

WARNING!

Injuries through improper use

Improper use of the instrument can lead to hazardous

situations and injuries.

tions may only be carried out by skilled personnel

who have the qualications 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-specic regulations, current standards

and directives, are capable of carrying out the work described and

independently recognising potential hazards.

3.5 Labelling, safety marks

Dial

Warning indicator

Colour change of the status display to

the red warning dot indicates a fault. See

chapter 6 “Faults”.

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 measuring instrument.

Permissible conditions at the place of storage

Storage and transport temperature: -30 ... +70 °C

Protect the instrument from dust.
