WARNING!
Before installation, commissioning and operation, ensure that the appropriate instrument 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!
Danger of injury and damage to property due to escaping media
Escaping media can lead to serious injury. In the event of failure, components can be ejected or media
exhausted under high pressure.
■
Open the connections only after the system has been depressurised.
■
For pressures from 1,000 bar, employ a protective device to prevent parts from being ejected. The
protective device must not be removable without the use of tools.
■
Always operate the pressure measuring instrument within the overpressure limit, see chapter
3 “Specications”.
■
Ensure that the pressure in the system as a whole does not exceed the lowest maximum pressure of
any of its components. If varying or dierent pressures are to be expected in the system, components
must be used that can withstand the maximum expected pressure spikes.
■
Observe the working conditions in accordance with chapter 3 “Specications”.
■
Actions or alterations to the pressure transmitter, which are not described in these operating
instructions, are not permitted.
Further important safety instructions can be found in the individual chapters of these operating
instructions.
2.1 Intended use
The pressure transmitter is an intrinsically-safe supplied pressure measuring instrument and is used for the continuous
monitoring of gaseous media or liquids in potentially explosive areas which require category 1, 1/2 and 2 equipment.
ATEX and IECEx approval:
