1. General information

The pressure gauge described in the operating instructions has

been designed and manufactured using state-of-the-art technology.

All components are subject to stringent quality and environmental

criteria during production. Our management systems are certied to

ISO 9001 and ISO 14001.

These operating instructions contain important information on

handling the pressure gauge. 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 accessible to

skilled personnel at any time.

Skilled personnel must have carefully read and understood the

operating instructions, prior to beginning any work.

The manufacturer’s liability is void in the case of any damage

caused by using the product contrary to its intended use,

non-compliance with these operating instructions, assignment of

insuciently qualied skilled personnel or unauthorised modica-

tions to the pressure gauge.

The general terms and conditions, contained in the sales documen-

tation, shall apply.

Subject to technical modications.

2. Safety

WARNING!

Before installation, commissioning and operation, ensure

that the appropriate pressure gauge has been selected in

terms of measuring range, design and specic measuring

conditions.

The compatibility of the materials under pressure with the

medium must be checked!

1. General information / 2. Safety

2080268.06 02/2013 GB/D/F/E

WIKA operating instructions pressure gauge, model 2 per ATEX

In order to guarantee the measuring accuracy and

long-term stability specied, the corresponding load limits

must be observed.

Non-observance can result in serious injury and/or

damage to equipment.

Further important safety instructions can be found in the

individual chapters of these operating instructions.

2.1 Intended use

These pressure gauges are used for measuring pressure within

hazardous areas in industrial applications.

The pressure gauge 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 qualication

WARNING!

Risk of injury should qualication be insucient!

Improper handling can result in considerable injury and

damage to equipment.

The activities described in these operating instructions

may only be carried out by skilled personnel who have

the qualications 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-specic regulations,

current standards and directives, are capable of carrying out the work

described and independently recognising potential hazards.

2.3 Safety instructions for pressure gauges per ATEX

WARNING!

Non-observance of these instructions and their contents

may result in the loss of explosion protection.

WARNING!

It is imperative that the application conditions and safety

requirements of the EC-type examination certicate are

followed.

Pressure gauges must be earthed via the process

connection!

Specications

Permissible temperatures

Ambient: Model 232/262 -40 ... +60 °C

Model 233/263 -20 ... +60 °C (glycerine lling)

-40 ... +60 °C (silicone oil lling)

Medium: The permissible medium temperature not only depends on

the instrument design, but also on the ignition temperature

of the surrounding gases, vapours or dusts. Both aspects

have to be taken into account.

For maximum permissible medium temperatures see table 1.

Attention! In the case of gaseous substances, the temperature may

increase due to compression warming. In these cases it may be neces-

sary to throttle the rate of change of pressure or reduce the permissible

medium temperature.

WARNING!

For hazardous media such as oxygen, acetylene, amma-

ble or toxic gases or liquids, and refrigeration plants,

compressors, etc., in addition to all standard regulations,

the appropriate existing codes or regulations must also be

followed.

For additional important safety instructions see chapter "2.3 Safety

instructions for pressure gauges per ATEX".

WARNING!

Residual media in dismounted pressure gauges can result

in a risk to persons, the environment and equipment.

Take sucient precautionary measures.
