2 Product and functional description

2.1 Delivery scope

• Diaphragm manometer DA09

• Operating Manual

2.2 Intended use

The diaphragm manometer DA09 serves to measure and display differential pressures in gaseous, fluid and aggressive media. The unit is completely made of CrNi-steel and is suitable for use in aggressive environments. If used with aggressive media, the media compatibility with the materials used must be checked (see Techn. data).

The DA09 can be delivered with a contact element. If the set limit values are exceeded, the output power circuits are opened or closed, and/or a 0/4…20 mA output signal proportional to the displayed value is issued for a capacitive rotation angle encoder.

DANGER

Installation regulations

The respective installation instructions must be observed for every application case. These should be listed in detail in the same-named section in chapter 'Assembly' for the 'use in explosive areas'.

8 / 40 BA_EN_DA09_EG_ATEX

2.4 Design and mode of operation

The measuring system comprises a diaphragm and two separate pressure chambers. Differential pressure between the chambers causes axial movement of the diaphragms. A tie rod transfers this movement to an indicator.

The seal between the pressure chamber and tie rod is realised with metal bellows. To compensate the static operating pressure, the measuring system is symmetrical.

3.1 General

The device can be mounted in one of the following ways:

1. Direct assembly The unit is suitable for direct assembly to pressure lines. The unit weight depends on the design. A suitable support construction may be needed.

2. Wall mounting The unit is equipped with a wall holder and is suitable for mounting to mounting plates and even walls.

3. Pipe assembly The device is equipped with a special pipe assembly set and is suitable for mounting to a 2" pipe (DN50).

Wall mount Pipe assembly

Fig.5: Assembly types

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. 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 commission-

ing, 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.

The process connections are marked with (+) and (-) symbols on the device. The pressure lines must be mounted according to these symbols.

Additional Attachments

Contact elements

Limit signal transmitters (contacts) and capacitive rotation angle transducers with an output signal proportional to the angular position can be fitted into a housing augmented by a corresponding bayonet ring connector.

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

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 Paraffin oil, glycerine, silicon oil Low-action contacts Paraffin oil, silicon oil Magnetic spring contacts Silicon oil Inductive contacts Paraffin oil, silicon oil Rotation angle transducer no filling possible

Marker needle

A settable red marker can be attached to the scale to clearly show a certain pressure (limit value).

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‘.

Shut-off fitting

Three-spindle equalisation and shut-off valve DZ93 or four-spindle equalisation and shut-off valve DZ94.

• Material 1.4404

• Functions: Shut-off, pressure compensation
