5 Separating membrane 6 Connecting rod
7 Measuring diaphragm 8 Pressure chamber
2.4 Design and mode of operation
The pressures in the pressure chambers that are to be compared are each exerted onto a measuring membrane that can be rigidly connected using a connection rod. To compensate the static pressure, the space between the separating and measuring membrane is filled with a pressure transfer fluid.
During pressure equalisation, the two measuring membranes are in an idle position. In case of pressure difference, the force acting on the membranes causes
it to be moved towards the side of the lower pressure.
The connecting rod transfers the deflection of the measuring membranes onto
the transfer lever mounted to the measuring shaft. Proportional to the current
differential pressure, the measurement shaft makes a rotational movement that
the indicator translates into a rotation angle between 0 and 270°.
In the case of one-sided pressure by the measuring system above and beyond
the measuring range, the over-pressure guard will be activated which supports
the overlosaded membrane.

3 Assembly
3.1 General information
The device can be mounted in one of the following ways (see Assembly):
1. Wall mounting
The device is designed for installation onto flat assembly plates. The unit is
equipped with a wall mounting plate for this mounting type.
2. Pipe assembly
The device is equipped with a special pipe assembly set and is suitable for
mounting to a 2" pipe (DN50).
3. Panel mounting
Panel mounting is available in two installation models.
– Panel mounting fittings (Type 1)
This variant is only suitable for models with a small measuring system
(Ø75) and a bayonet ring casing NG100.
– Panel installation with front ring (Type 2)
All models are suitable for this variant. A suitable steel construction
must be used to ensure that the front plate can bear the weight of the
DA03. This is possible e.g. by means of a combination with the wall or
pipe assembly.
At the factory, the device is calibrated for vertical installation, but the installation
position is arbitrary. For any installation positions that are not vertical, the zeropoint signal can be corrected via the installed offset correction.
To ensure safety during installation and maintenance, we recommend installing
a suitable shut-off valve on the system (see accessories).
3.2 Process connection
• By authorized and qualified specialized personnel only.
• The pipes need to be depressurized when the instrument is being connected.
• Appropriate steps must be taken to protect the device from pressure surges.
• Check that the device is suitable for the medium being measured.
• Maximum pressures must be observed (cf. Tech. data)
All supply lines are arranged so that there are no mechanical forces acting on
the device.
The pressure lines must be kept as short as possible and installed without any
tight bends to avoid delays.
The pressure lines must be installed at an inclination so that when fluids are
measured no air pockets are created or when measuring gases, no water pockets are created. If the required inclination is not reached, water or air filters must
be installed at suitable places.
The pressure lines need to be vented for fluid measuring media. [}15].
If water is used as a measuring medium, the unit must be protected against
frost.
If the pressure sensing lines are already pressurised at the time of commissioning, zero-point control and adjustment cannot be performed. In such cases, the
device should be only connected to the mains without the pressure sensing
lines.

4.1 General
All electrical supply, operating and measuring lines, and the pressure connections must have been correctly installed before commissioning. All supply lines
are arranged so that there are no mechanical forces acting on the device.
Check that all pressure connections are free of leaks before commissioning.
In models filled with fluid, the venting valve on the upper side of the bayonet
casing must be opened before commissioning! To do this, turn the venting
screw anticlockwise as far as it will go.
Fig.17: Venting valve
4.2 Venting of the pressure lines
WARNING
Risk connected to pressure
Never remove the venting screw if the unit is still pressurised! Close the shut-off
valves of the flanged fittings or depressurize the system.
The pressure lines need to be vented for before commissioning on devices that
work with fluid media. Proceed as follows:
• Remove the venting screws of the two pressure chambers.
• Carefully increase the system pressure until the fluid level is 5 mm below
the sealing surface of the threaded borehole.

A certain minimum pressure level is required to operate this kind of contact element, which is why there is a lower limit for the mbar measuring ranges. This
limit depends on the model type and is stated in the section ‚General‘.
The measuring deviation increases by ±0.5% per contact when the contacts are
driven and switched.
For more information and the order key, please refer to the data sheet:
• for limit switch in data sheet KE
• for rotation angle converter in the data sheet KE09
6.4.1.2 Fluid charging
Under aggravated operating conditions, such as vibrations and extreme pressure fluctuations, or in order to avoid condensation forming if used outdoors, the
casing can be filled with the following fluids depending in the type of contacts installed:
without contacts Glycerine, silicon oil
Low-action contacts Silicon oil
Magnetic spring contacts Silicon oil
Inductive contacts Paraffin oil
Rotation angle transducer no filling possible
6.4.1.3 Marker needle
A settable red marker can be attached to the scale to clearly show a certain
pressure (limit value).
6.4.1.4 Trailing needle
The railing needle is 'dragged' with the measured value indicator. As there is no
fixed connection between the two needles, one-off maximum values are stored.
The trailing needle can be reset using an adjusting dial in the window. Trailing
needles cannot be used in conjunction with contacts. A certain minimum pressure level is required to move the drag indicator, which is why there is a lower
limit for the mbar measuring ranges. This limit depends on the model type and
is stated in the section ‚General‘.
