1. Safety instructions / 2. Measuring principle
1. Safety instructions
GB
Please observe the following operating parameters
The relevant national safety provisions (e.g. VDE 0100) must be
observed when mounting, putting into commission and operating this pressure transmitter. Severe injuries and/or damage
might occur as a result of non-compliance with the corresponding provisions. Only qualified personnel is authorised to work on
these instruments.
The pressure transmitter is exclusively suitable for dry, clean,
non-aggressive gases.
Do not blow into the process connections!
The measuring cell might be damaged by the respiratory
pressure.
Max. medium/ambient temperature: 10 ... 50 °C
It has to be made sure that during transportation both
process connections are open. Instruments with absolute
pressure measuring ranges must be transported in pressure
compensation cabins.
2. Measuring principle
The pressure mesurement is realised via a sensitive diaphragm or, in the case of
absolute pressure measuring ranges, a capsule which is adapted to the measuring
range. An inductive system generates a linear signal which changes in proportion to
the prevailing pressure.

3. Mounting
3. Mounting
The differential pressure transmitter is designed for wall-mounting. After unscrewing
the two screws at the case the black connection socket can be pulled off the case.
The socket has rated break points for the fastening screws.
3.1 Mounting instructions
The wall-mounting should be carried out in a vertical position, i.e. the process
connections facing down, because the instrument was adjusted in this position.
Thus a possible condensate penetration into the pressure line is avoided.
The mounting location should be free of shocks, vibrations and heat irradiation.
The instrument should not be mounted in the close environment of sources of
interference (e.g. transformers, motors, senders).
3.2 Process connections
GB
2 x hose connection 6.6 x 11 mm
for hoses with an inside diameter of 5 ... 6 mm.
Pressure is to be connected to the „+“ connection.
Vacuum is to be connected to the „-“ connection.
Instruments with absolute pressure measuring ranges have only
one process connection.

6. Calibration instructions
6. Calibration instructions
GB
Please start the calibration only after a running-in period of approx.
30 - 60 minutes.
6.1 Zero point adjustment (Z)
For the zero point adjustment both process connections must be open. After pulling
off the rubber plugs at the instrument‘s front the output signal can be adjusted with
the zero potentiometer (Z).
For the adjustment of pressure transmitters with absolute pressure measuring range
the process connection is to be connected to a pressure generator and an absolute
pressure reference via a T-piece. Subsequently an absolute pressure is generated for
which the output signal shall be: 0 V / 0 mA or 4 mA. Now the output signal can be
adjusted with the zero potentiometer (Z).
6.2 Span adjustment (S)
For the span adjustment the nominal pressure must be connected via a T-piece from
the pressure generation to the pressure reference and the pressure channel.
The WIKA precision calibrator model CPC2000, which has a pressure generation
and a pressure reference, is excellently suitable for this task.
Pressure is to be connected to the “+” connection and vacuum to the “-” connection. Now the output signal may be adjusted with the span potentiometer (S).
6.3 Adjustment of the alarm contacts
For the adjustment of the alarm contacts the reference pressure must be applied
at which the contact is supposed to close. This is accomplished with a pressure
generator which is connected to the pressure reference and the pressure channel via
a T-piece. Pressure is to be connected to the “+” connection and vacuum to the “-”
connection. The potentiometer of the switch point SP I or II must be adjusted until
the red LED above the respective potentiometer lights up, i.e. the switch value has
been reached and the contact closes.

6. Calibration instructions
Then the pressure at which the contact is desired to break again must be applied.
Now the respective hysteresis potentiometer must be adjusted ( ) until the LED
goes out again. The switching hysteresis is adjustable within a range of 0 ... 15 %.

Beachten Sie unbedingt bei Montage, Inbetriebnahme und
D
Bitte beachten Sie folgende Betriebsparameter
Betrieb dieses Druckmessumformers die entsprechenden nationalen Sicherheitsvorschriften
(z. B.: VDE 0100). Bei Nichtbeachten entsprechender
Vorschriften können schwere Körperverletzungen und/oder
Sachschäden auftreten.
Nur entsprechend qualifiziertes Personal darf an diesen Geräten
arbeiten.
Der Druckmessumformer ist ausschließlich für trockene,
saubere, nicht aggressive Gase geeignet.
Nicht in die Prozessanschlüsse blasen!
Die Messzelle kann durch den Lungendruck beschädigt
werden.
Max. Messstoff-/Umgebungstemperatur: 10 ... 50 °C
Beim Transport ist darauf zu achten, dass beide Prozessan-
schlüsse offen sind. Geräte mit Absolutdruck-Messbereichen
müssen bei Luftfracht in Kabinen mit Druckausgleich befördert werden.
2. Messprinzip
Die Druckmessung erfolgt über eine dem Messbereich angepasste, empfindliche
Plattenfeder, bzw. einer Kapselfeder bei Absolutdruck-Messbereichen. Ein induktives System erzeugt ein lineares Signal, das sich proportional zum anstehenden
Druck verändert.
