WIKA Operating Instructions - Differential pressure transmitter DPT-10
Information:
The DPT10 is also suitable for bidirectional flow measurement (flow
in both directions). The selection is carried out in the menu item
"
Linearization curve
". With the bidirectional flow measurement, the
min. adjustment value must be equal to the negative max. adjustment
value.
Example: Max. adjustment value
+100 mbar
, as min. adjustment
value,
-100 mbar
must hence be entered.
The min. adjustment is finished.
Proceed as follows:
1. Edit the bar value in the menu item "
Max. adjustment
" with
[OK]
.
Max. adjustment

- +
=
0.5000 bar
0.0000 bar
Information:
If the instrument has not yet been adjusted, the displayed pressure for
100 % corresponds to the nominal measuring range of the sensor (in
the above example 500 mbar).
2. Set the requested mbar value with
[->]
and
[OK]
.
3. Confirm with
[OK]
and move to the menu overview with
[ESC]
.
For an adjustment with flow, simply enter the actual measured value
indicated at the bottom of the display.
The max. adjustment is finished.

To damp process-dependent measured value fluctuations, set an
integration time of 0 … 999 s in this menu item.
Depending on the sensor type, the factory setting is 0 s or 1 s.

For level measurement, a linearization is necessary for all vessels in
which the vessel volume does not increase linearly with the level - e.g.
in a cylindrical or spherical tank - and the indication or output of the
volume is requested.
Respective linearisation curves are stored for these vessels. They
indicate the relation between the percentage level and the vessel vol-
ume. By activating the suitable curve, the percentage vessel volume
is displayed correctly.
