Notes on Safety

Approved usage The Deltabar S is a differential pressure transmitter for measuring differential pressure,

flow and level.

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.

Symbol Meaning

Note!

A note highlights actions or procedures which, if not performed correctly, may indirectly affect

operation or may lead to an instrument response which is not planned.

Caution!

Caution highlights actions or procedures which, if not performed correctly, may lead to

personal injury or incorrect functioning of the instrument.

Warning!

A warning highlights actions or procedures which, if not performed correctly, will lead to

serious personal injury, a safety hazard or destruction of the instrument.

Device certified for use in explosion hazardous area

If the device has this symbol embossed on its name plate it can be installed in an explosion

hazardous area.

Explosion hazardous area

Symbol used in drawings to indicate explosion hazardous areas.

– 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.

Deltabar S Notes on Safety

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%.

Open 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 is open to

atmosphere pressure.

•A trap prevents the build up of dirt in

the pressure piping.

•Install the pressure piping with a

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

process.

•Install the pressure piping with a

continuous fall of at least 10%.

Closed tank with

steaming liquid

PMD 25 K

•Mount the Deltabar S below the lower

•The tapping for the negative side must

be above the maximum level to be

measured. The condensate trap

ensures a constant pressure.

•Traps prevent the build up of dirt in the

pressure piping.

•Use a three-way manifold for simple

mounting without interruption of the

process.
