1. General information

1. General information

■

The transmitter 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.

■

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 accessible to skilled personnel at any time.
Pass the Operating Instructions onto 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 manufacturer's liability is void in the event 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cations to the instrument.

■

The general terms and conditions contained in the sales documentation shall apply.

■

2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the appropriate 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 chapters 4, 5 and 6.

■

Always operate the transmitter within the overpressure limit.

WARNING!

Risk of burn injury due to high uid temperatures

■

Do not touch with bare hands the parts of the device that are in contact with the uid.

■

Use safety gloves to handle the device.

■

Before opening the pipe, stop the circulation of uid and drain the pipe.

■

Before opening the pipe, make sure the pipe is completely empty.

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

2.1 Intended use

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

For applications with direct contact with foodstus, only use the transmitter 8325-F, ush diaphragm.

Only use the transmitter in applications that lie within its technical performance limits (e.g. max. ambient temperature,
material compatibility, ...).

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 opera­tion of the transmitter outside of its technical specications requires the instrument to be taken out of service immedi-

ately and inspected by an authorised Bürkert 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 transmitters can result in a risk to persons, the environment and equipment.

Take sucient precautionary measures.

Do not use this instrument in safety or emergency stop devices. Incorrect use of the instrument can result in injury.
Should a failure occur, aggressive media with extremely high temperature and under high pressure or vacuum may
be present at the instrument.
