Dear customer,
Your VACUUBRAND vacuum gauge shall support you at your work for a long time without any trouble and
with full load output. Thanks to our large practical experience we attained much information how you could
add to an efficient application and to personal safety. Please read these instructions for use prior to the
initial start-up of your controller.
VACUUBRAND vacuum gauges are the result of many years of experience in construction and practical
operation of these vacuum gauges combined with the latest results in material and manufacturing technology.
Our quality maxim is the ”zero fault principle”:
Every delivered vacuum gauge is tested extensively including an endurance run. Due to this endurance
run, also faults, which occur rarely, are reported an can be corrected. Every single vacuum gauge is tested
on achievement of the specification after the endurance run.
Every VACUUBRAND controller leaving our factory achieves the specification. We feel obliged to
this high quality standard.
We are aware that the controller should not draw a part of the real work and we hope to contribute with our
products to an effective and troublefree realisation of your work.
Yours
VACUUBRAND GMBH + CO KG
After sales service: Contact your local dealer or call (++49) 9342/808-193.

has an approval for zone 0.
Prevent any condensate to reach the pressure transducer inside the vacuum gauge (risk of false
measurement).
Max. permitted pressure at the vacuum gauge:
☞ DVR 3: 1.1 bar absolute; with small flange connection 2.5 bar absolute.
☞ DVR 4 / DVR 4S: 2.5 bar absolute; when using clamping rings made of stainless steel, the max.
permitted pressure at the measuring connection is 6.0 bar absolute.
☞ The display flashes at a pressure above 1060 mbar.
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 / DVR 4 / DVR 4S within the hazardous area of category 2 (according to the approvals of power
