Mounting,
commissioning
operation
The device has been designed to operate safely in accordance with current technical,
safety and EU standards. If installed incorrectly or used for applications for which it is
not intended, however, it is possible that application-related dangers may arise, e.g.
product overflow due to incorrect installation or calibration. For this reason, the instrument
must be installed, connected, operated and maintained according to the instructions in
this manual: personnel must be authorised and suitably qualified. The manual must have
been read and understood, and the instructions followed. Modifications and repairs to
the device are permissible only when they are expressly approved in the manual.
Explosion hazardous
areas If the device is to be installed in an explosion hazardous area, then all national regulations
must be observed. The instrument can be delivered with the certificates listed in the table
below. The certificate can be identified from the first letter of the order code stamped on
the nameplate.
•Ensure that all personnel are suitably qualified.
•All measurement and safety regulations which apply to the measuring point are to
be observed.

– Devices located in and wiring entering areas with the designation "explosion hazardous
areas" must conform with the stated type of protection.
Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion hazardous areas.
– Devices located in safe areas still require a certificate if their outputs run into explosion
hazardous areas.
Direct voltage
A terminal to which or from which a direct current or voltage may be applied or supplied.
Alternating voltage
A terminal to which or from which an alternating (sine-wave) current or voltage may be
applied or supplied.
Grounded terminal
A grounded terminal, which as far as the operator is concerned, is already grounded by
means of an earth grounding system.
Protective grounding (earth) terminal
A terminal which must be connected to earth ground prior to making any other connection to
the equipment.
Equipotential connection (earth bonding)
A connection made to the plant grounding system which may be of type e.g. neutral star or
equipotential line according to national or company practice.

1 Introduction
Application The Deltabar S family of devices is used for the measurement of differential pressure, level
and flow in gases, vapours and liquids. They are used in all sectors of industry.
Operating principle
Metal sensor
The system pressure deflects the separating diaphragm and a fill fluid transmits the
pressure to a resistance bridge. The pressure dependent change in bridge output
voltage is measured and processed further.

1.1 Measuring system
In the simplest case, the complete measuring system comprises
•a Deltabar S with 4…20 mA current output
•an optional four-character display for pressure
•power supply unit for 11.5 to 45 V DC
The HART protocol versions have a digital communication signal superposed on the
current signal which is used for remote calibration.
These transmitters have extended functions so that level or flow can also be measured.
The device is operated:
•via the Commuwin II operating program
•via the Universal HART Communicator DXR 275 handheld (HART protocol).

2 Installation
This chapter describes the measuring set-up of the Deltabar S and the electrical
connection.
2.1 Measuring system for differential pressure measurement
Note!
•General recommendations for laying pressure piping may be taken from
DIN 19210 "Methods for measurement of fluid flow; differential pressure piping for
flow measurement devices" or the appropriate national or international standards.
•Check that pressure piping installed outdoors is adequately insulated and/or heated.
Gases and vapours •Mount the Deltabar S above the
tapping point, so that condensation can
run back into the process piping.
•Use a three-way manifold for simple
mounting without interruption of the
process.
•Install the pressure piping with a
continuous fall of at least 10%.
Liquids •Mount the Deltabar S below the tapping
point, so that the pressure piping is
always filled with liquid and gas
bubbles can back into the process pipe.
•Use a three-way manifold for simple
mounting without interruption of the
process.
•In order to avoid build-up in dirty
liquids, it is recommended that traps
and drain cocks are used.
•Install the pressure piping with a
continuous fall of at least 10%.

continuous fall of at least 10%.
Closed tank
PMD 25 K
•Mount the Deltabar S below the lower
tapping so that the pressure piping is
always filled with liquid.
•The negative side must be above the
maximum level to be measured.
•Traps prevent the build up of dirt in the
pressure piping.
•Use a three-way manifold for simple
mounting without interrupting the
