TERMS USED IN THIS MANUAL

ATEX

Directive 94/9/EC, commonly called the

ATEX („Atmosphères Explosibles“) products

directive.

Dilution

The continuous supply of a protective gas,

after purging, at such a rate that the con-

centration of a ammable mixture inside the

pressurized enclosure is maintained at a

value outside the explosive limits except in a

dilution area.

Containment System

The part of the analyzer containing the gas

that may constitute an internal source of re-

lease.

Flammable Gas(es)

Gases and gas mixtures are assigned to be

ammable if they might become ignitable

when in a mixture with air.

Area Classication

Zone 1

Where ignitable concentrations of ammable

gases can exist some of the time under nor-

mal operating conditions.

(A guideline value [not part of a standard ] is

10 to 1.000 hours per year.)

Equipment to be used in Zone 1 has to be

classied Category 2.

Zone 2

Where ignitable concentrations of ammable

gases are not likely to exist under normal

operating conditions.

(A guideline value [not part of a standard ] is

less than 10 hours per year.)

Equipment to be used in Zone 2 has to be

classied Category 3.

External Explosion Protection

The „External explosion protection“ serves to

prevent penetration of explosive gas mixtu-

res into the analyzer enclosure. In addition it

avoids ignition on the surface. For this reason

the analyzer is purged with protective gas and

held at an internal overpressure compared to

the surrounding atmosphere.

Explosive Gas(es)

Flammable gases and gas mixtures of a

concentration within the explosion limits and

present in mixture with air.

Terms used in this manual

Pre-Purging

The pre-purging phase serves to remove any

combustible gas out of the analyzer’s enclos-

ure prior to switching on the analyzer. During

this time the housing is purged with 5 times

its own volume.

Lower Explosion Limit (LEL)

Volume ratio of ammable gas in air below

which an explosive gas atmosphere will not

be formed: the mixture of gas and air lacks

sufcient fuel (gas) to burn.

Purge mode „Continuous Flow“

In EEx p „continuous ow mode“ the protec-

tive gas ows with higher rates through the

enclosure. Flow rates are calculated to hold

an overpressure of > 1 mbar compared to

atmospheric.

Protective Gas

Air or inert gas used for purging and maintai-

ning an overpressure and, if required, diluti-

on.

Purge mode „Leakage Compensation“

In EEx p „leakage compensation mode“ just

as much protective gas is used to hold an

overpressure of > 1 mbar compared to at-

mospheric.

Upper Explosion Limit (UEL)

Volume ratio of ammable gas in air above

which an explosive gas atmosphere will not

be formed: the mixture of gas and air is too

rich in fuel (decient in oxygen) to burn.

Internal Explosion Protection

The „Internal explosion protection“ serves

to prevent ignition of gas being present in

the analyzer’s Containment System (CS;=

sample gas path).

Dependent on the gas composition several

options are available:

None required (if gas is noncombustible),

dilution by purge gas or/and internal overpres-

sure of the analyzer’s enclosure compared

to the CS.

CHAPTER 1

Technical Description

1.1 Application and Principle of Operation

The gas analyzers of type BINOS



100 F and

MLT 2 are intended to measure gas compon-

ents within gas mixtures. In combination with

an appropriate certied pressurization system

(protection method „Pressurized Enclosure“

Ex p) they can be installed and operated in

hazardous areas of Zone 2.

Pressurization acts as external explosion

protection and prevents external explosive

atmosphere to penetrate into the analyzer

by holding the enclosure at an overpressure

compared to the surrounding

The type of purge system used varies de-

pendent on the area where the analyzer is

intended to be installed. Both systems offer

two modes of operation:

• Ex p with continuous ow

and

• Ex p with leakage compensation.

Dependent on the sample gas composition it

may be necessary to take care of internal explo-

sion protection which refers to the sample gas

path (containment system) in the analyzer.

One has to differentiate between the following

measurement applications:

• Nonammable gases and gas mixtu-

res below the LEL: It must be ensured

that the sample gas in the containment

system always remains below the lower

explosive limit!

• Flammable gases and gas mixtures

may be analyzed using an analyzer with

pressurization method „leakage compen-

sation“ when the sample gas is diluted

below ¼ LEL outside the analyzer, so the

resulting sample gas is to be categorized

„nonflammable“. The diluting system

must ensure that the gas in the contain-

ment system always remains below ¼

LEL.

• Flammable gases and gas mixtures

may be analyzed using an analyzer

with pressurization method „leakage

compensation“ or „continuous flow“

when the analyzer enclosure has an

internal overpressure of > 50 Pa above

the pressure in the containment system.

To ensure this condition a differential

pressure switch is used and connec-

ted between containment system and

analyzer enclosure, activating an alarm

contact in case the pressure decreases

below the level of 50 Pa. For Category 2

instruments the purging unit disconnects

the analyzer from it’s power supply and

starts a prepurge phase. For Category 3

instruments the operator has to ensure

the alarm signal is interpreted in a proper

way. If more than one switch is needed

because more than one ammable gas is

supplied to the analyzer, the contacts of

these switches have to be connected in

series. Purge medium may be inert gas

or air.

Depending on the measured gas and

methode infallible containments may be

used, so differential pressure switches

become redundant.
