8.4 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...1000 bar absolute pressure
can be connected to the device.
8.5 Relative Pressure Sensors (Types: HND-PS01…-PS05, HND-
PS09)
For measurements of over- or under pressure:
Connect plastic tube with internal dia of 4 mm to pressure port "B". Port "A" is not
used!
For measurements of under pressure:
(with higher negative measuring
range)
Connect plastic tube with internal dia of 4 mm to pressure port "B". Port "A" will not
be used!
Pressure sensors HND-PS01, HND-PS02 and HND-PS03 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).
Note: All values are displayed now as positive values. No minus sign will be
shown. Example: it is possible to measure under pressure down to -
25.00 mbar, the display shows then the value 25.00 (no minus sign).
For measurements of differential pressure:
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".
Stainless steel pressure sensors: (types: HND-PS01…-PS30)
For measurements of over-, under- or absolute pressure screw sensor to G1/4"
pressure terminal or plug plastic tube to a suitable adapter.
Measurements of differential pressure with two sensors
By means of the calculation sensor 1 – sensor 2 (DIF) press. differences of any
sensor combinations can be measured.
