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.
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.
The instrument is exclusively intended for use in an industrial environment. In residential areas, measures for
radio interference suppression may have to be taken.
The technical specications contained in these operating instructions must be observed. Improper handling or
operation 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 Festo 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 if qualication is 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 environ-
ment and equipment.
Take sucient precautionary measures.

1) The power supply for the pressure transmitter must be made via an energy-limited electrical circuit per UL/EN/IEC 61010-1 or an LPS to UL/EN/IEC 60950-1 or
class 2 per UL1310/UL1585 (NEC or CEC).The power supply must be suitable for operation above 2,000 m should the pressure transmitter be used at this altitude.
Only ever use a power source that ensures a safe electrical isolation of the operating voltage in accordance with IEC/DIN EN 60204-1. In addition, observe the
general requirements for PELV circuits in accordance with IEC/DIN EN 60204-1. Switching power supply units are permissible, if they ensure a safe isolation as
dened by IEC/EN 60950-1.
2) Including linearity, hysteresis, zero oset and end value deviations (corresponds to measured error per IEC 61298-2). Calibrated in vertical mounting position with
process connection facing downwards.

4. Design and function
4.1 Description
By means of a sensor element and by applying power, the prevailing pressure is converted into an amplied
standardised electrical signal via the deformation of a diaphragm.This electrical signal varies in proportion to
the pressure and can be evaluated accordingly.
5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.
