7.7 Calibration Services
Calibration certificates – DKD-certificates – other certificates:
If device should be certificied for its accuracy, it is the best solution to return it
with the referring sensors to the manufacturer.
Only the manufacturer is capable to do efficient recalibration if necessary to get
results of highest accuracy!
7.8 Pressure Connection To The Sensors
The device is designed to be connected to the sensors of the HND-PS...-series
without a new calibration being necessary. Therefore a great variety of
replaceable sensors of e.g. –1.999...2.500 mbar relative up to 0...400.0 bar
absolute pressure can be connected to the device
(p.r.t. chapter
10.1 Pressure
sensors)
7.8.1
Relative Pressure Sensors
For measurements of over- or under pressure:
Connect plastic tube with internal dia of 4 mm to pressure port "B". Port "A" will
not be used!
Pressure sensors HND-PS01, -PS02 and –P03 allow for measurements of
under pressure up to the entire over pressure measuring range by re-plugging
the tube to pressure port "A". Please note that all values are displayed as
positive values. No minus sign will be shown. (Example for HND-PS02: For
tube connection "B" the measuring range covers -19.99 to 25.00 mbar. If you
replug to port "A" under pressure measurements down to -25.00 mbar could be
carried out with the display showing the value 25.00 (no minus sign).
For measurements of pressure differences:
Connect both plastic tubes with an internal dia of 4 mm to pressure port "B"
and "A"; make sure to apply higher pressure to port "B".
7.8.2
Absolute pressure sensors:
Connect plastic tube with an internal dia of 4 mm to pressure port "A". (Port "B" is
not used.)
7.8.3
Stainless steel pressure sensors:
For measurements of over-, under- or absolute pressure screw sensor to G1/4"
pressure terminal or plug plastic tube to a suitable adapter.
