2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the appropriate pressure transmitter has been

selected in terms of measuring range, design and specic measuring conditions.

Non-observance can result in serious injury and/or damage to the equipment.

WARNING!

■

Open the connections only after the system has been depressurised.

■

Observe the working conditions in accordance with chapter 3 "Specications".

Further important safety instructions can be found in the individual chapters of these operating instructions.

2.1 Intended use

The pressure transmitter is used to convert pressure into an electrical signal.

With hydrogen applications, use is only permitted when a medium and ambient temperature of 30 °C

is not exceeded.

For applications with direct contact with foodstus this pressure transmitter is not suitable.

The instrument has been designed and built solely for the intended use described here, and may only be used

accordingly.

The technical specications contained in these operating instructions must be observed. Improper handling or opera-

tion of the pressure transmitter outside of its technical specications requires the instrument to be taken out of service

immediately and inspected by an authorised WIKA service engineer.

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.

Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

2.3 Special hazards

WARNING!

For hazardous media such as oxygen, acetylene, ammable 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.

WARNING!

Residual media in dismounted pressure transmitters can result in a risk to persons, the environment and

equipment.

Take sucient precautionary measures.
