Intended use
• The devices DVR 3 are electronic rough vacuum gauges of the facility perfor-
mance group II for the intended use in hazardous areas. They have a special
approval and are subject to the guideline 94/9/EG (see ”Declaration of Confor-
mity)”.
• Respect the permitted connection parameters.
Attention: DVR 3 has only an approval for zone 1 and zone 2.
• Electrical and vacuum components might require a separate approval (see also
”Accessories”).
• The device is designed for ambient and gas temperatures at the pressure trans-
ducer connection of +10°C to +40°C at continuous operation, up to +80°C for
short periods (< 5 minutes) at the pressure transducer. If installing the device into
a cabinet or a housing check maximum temperature. Ensure that the maximum
permitted gas temperature at the pressure transducer (see ”Technical data”) is
not exceeded.
Use the equipment and all system parts for the intended use only, i.e. for measure-
ment of vacuum in vessels designed for that purpose.
Connecting the device
• Connect the vacuum gauge to the vacuum application.
• Position the vacuum gauge and its vacuum connection line so that condensate
cannot flow towards the internal pressure transducer.
• Connect hoses at the pressure transducer connection gas tight.
• Ensure stability of the hose connection.
• Comply with all relevant safety requirements.
☞ Avoid uncontrolled overpressure (e. g. when connecting to a locked or blocked
tubing system). Risk of bursting.
☞ The power supply unit BVE 9V is an intrinsically safe electrical operating device
of the facility performance category 2 (PTB 98 ATEX 2206). The user can replace
the sealed power supply unit of vacuum gauges DVR 3 within the hazardous
area of category 2 (according to the approvals of power supply unit and vacuum
gauge). Further interventions and repair must only be done by the manufacturer.
☞ Using non-genuine power supply units or doing further interventions void the ap-
proval for use in explosive areas.
• Power supply by an power supply unit BVE 9V. Do not charge the battery. Do not
open the battery. Do not throw the battery into fire. Do not heat over 100°C and
do not bring in contact with water.
