Cleaning the pressure transducer
Adjustment of the pressure transducer
For adjusting the pressure transducer, either a vacuum controller CVC 3000 or a vacuum gauge DCP
3000 is required,
Depending on operation conditions, accuracy requirements and the type of application, an inspection
and a readjustment may be necessary. It may also be required to readjust the pressure transducer after
it has been cleaned. (See the manual of the vacuum controller CVC 3000 or of the vacuum gauge DCP
3000 for instructions on adjustment. Download the latest version at www.vacuubrand.com)
Attention: Never use a spiky or sharp-edged tool to clean the pressure transducer.
VSK 3000: Never touch the ceramic diaphragm at the back of the measuring cham-
ber with hard objects!
VSP 3000: The interior of the pressure transducer is highly sensitive! Do not insert
fingers or tools into the measuring chamber.
Clean a contaminated pressure transducer as follows:
➨
Fill the measuring chamber with a solvent (e.g., benzene) and allow sufficient cleaning time. Observe
all regulations concerning usage and disposal of solvents!
➨ Drain the solvent and dispose of in accordance with regulations, repeat cleaning if necessary.
➨ Rinse the measuring chamber several times with alcohol in order to remove all solvent residues.
➨ Allow the pressure transducer to dry.
➨
Readjust the pressure transducer if necessary.
Calibration in the factory
Control of measuring equipment
The VACUUBRAND DAkkS calibration laboratory is accredited by the Deutsche Akkreditierungss-
telle GmbH (national accreditation body of the Federal Republic of Germany) for the measurable vari-
able pressure in the pressure range from 7.5*10 -4 Torr to 975 Torr (10 -3 mbar to 1300 mbar) in
accordance with the general criteria for the operation of testing laboratories defined in the DIN EN ISO/
IEC 17025:2000 series of standards (accreditation number D-K-15154-01). The DAkkS is signatory to
the multilateral agreements of the European cooperation for Accreditation (EA) and of the International
Laboratory Accreditation Cooperation (ILAC) for the mutual recognition of calibration certificates.
Rely on calibration in the VACUUBRAND calibration laboratory:
- To meet the requirements of the DIN ISO 9000ff and 10012 series of standards regarding the calibra-
tion of inspection, measuring and test equipment at specified intervals.
- To document that the vacuum gauges calibrated are traceable to national standards of the PTB
(Physikalisch-Technische Bundesanstalt; German national institute for science and technology and
the highest technical authority of the Federal Republic of Germany for the field of metrology and
certain sectors of safety engineering).
NOTICE
With the devices CVC 3000 and DCP 3000 it is possible to adjust and to configure the pressure trans-
ducer VSP 3000. (A configuration of the VSP 3000 e.g., to a different VACUU•BUS address, is required
if more than one pressure transducer are connected to a CVC 3000 or DCP 3000.)
Additional instructions for use regarding the configuration of pressure transducers or other
VACUU•BUS components are available upon request.
During operation
Over the whole measuring range the pressure reading is indicated in exponential notation.
