1.3 About the Analyzer

The G36 Oxygen Analyzer continuously measures the content of oxygen with concentra-

tions up to 21.0%. The G36 Oxygen Analyzer can be used to measure the content of oxy-

gen in N2or CO2based inert gas, in stack gas, or in connection with exhaust gas recircu-

lation (EGR).

The G36 Oxygen Analyzer uses a zirconia sensor. The zirconium dioxide sensors have

long been established as industry standards. The G36 uses a new type of zirconia sensor,

which can be used in a wide range of applications.

G36Oxygen Analyzer

Version 2.11 - March 2022 7

The most important element

of the sensor is the zirconia

cell. At high temperatures,

the oxygen ions can diffuse

through the zirconium diox-

ide membrane. When the

membrane is exposed to an

environment that contains

different amounts of oxygen

(e.g. the sensor internal refer-

ence gas on one side and

sample gas on the other), na-

ture seeks to balance itself,

and the transportation of ions

through the membrane will

generate an electrical charge.

ZrO2

Figure 1-1: Simplified schematic of the zirconia cell

This charge depends on the amount of the passing oxygen ions i.e. the difference between

the oxygen levels in the sample gas and the reference gas. This voltage will be detected

and converted into a signal that is proportional to the oxygen concentration in the sample

gas. The signal will be processed in the analyzer and the oxygen concentration of the

sample gas will be shown in the display.

The G36 Oxygen Analyzer has CE and MED markings as well as DNV, Bureau Veritas,

and Lloyds Register Type Approvals.

3Safety Aspects

Attention

•Follow the operating instructions!

•Make sure that all power and signal cables are connected correctly before

operating the analyzer.

•The sensor and sensor housing are hot and can cause severe burning of

personnel if not handled with care.

•The G36 Oxygen Analyzer is only suitable for installation in a safe, non-

hazardous area and not suitable for use with flammable sample gases.

•It should be pointed out that installation and operation of the G36 Oxygen

Analyzer and associated equipment must be carried out by skilled, trained,

and certified personnel, and that Green Instruments A/S does not take any

responsibility for the operation of the analyzer and associated equipment

whatsoever.

•The analyzer must only be applied as described in this instruction manual. If

the analyzer is used in a manner not specified by Green Instruments, the

protection provided by the analyzer may be impaired.

•Successful and safe operation of this equipment depends on proper handling,

installation, operation, and maintenance.

Hazardous voltage!

Always disconnect power before installing or servicing the analyzer. Ignoring this warn-

ing can result in severe personal injury or material damage. Read the instruction carefully

to ensure correct connection of all power and signal leads. Make sure that the correct

voltage is connected to the analyzer (see rating marked on the analyzer name plate).

Circuit breaker!

The installation must include a way to switch off the electrical power by a clearly marked

switch or circuit breaker external to the analyzer. The external switch or circuit breaker

shall be placed in close proximity to the analyzer and within easy reach of the operator.

Overload protection!

For compliance with the IEC 61010-1 (2003) safety requirements, the installation must

include a means of overcurrent protection to provide protection against excessive energy

being drawn from the power supply system in case of a fault in the analyzer.

Safety Aspects

Protective earth!

The analyzer must be connected to protective earth.

Installation and fault finding!

Electrical installation and fault finding on the analyzer should only be undertaken by a

suitably trained and qualified engineer.

EMC!

For compliance with the EMC product standard IEC 60533 (1999), the connection cables

for the main supply, relays, interface, and analog output signals should be shielded or

provided with equivalent protection.

Special precautions have to be taken in connection to "long" signals or control lines of

more than 30 meter.

Sensor!

The sensor must not be exposed to strong mechanical shocks. Otherwise the sensor ele-

ment may crack without visible damage.

The sensor must be connected to the analyzer before the analyzer is powered up (risk of

damage). As soon as the analyzer is under voltage, the connection to the sensor must not

be interrupted. Therefore, please disconnect the power when you need to connect or dis-

connect the sensor.

Connections!

All electrical connections and power supplies are placed inside the analyzer. To gain ac-

cess, unbolt the top cover of the analyzer using a standard 4-6 mm screwdriver.

Poisonous gases!

Both sensor types, SEN1 and SEN9, used for the G36 Oxygen Analyzer are not suitable

for installation in areas with a high concentration of methane (CH4).

Besides, a reduced life time can occur if the sensor is subjected to lead, phosphor, silicon,

halogens or high concentration of sulfur.

Recycling!

Please do not dispose the G36 Oxygen Analyzer with regular refuse. Disposal should be in

accordance with the requirements of the current statutory regulations.

Caution, risk of danger

Caution, hot surface

Caution, risk of electrical shock

Protective earth

The CE mark proves the compliance of the instrument with the requirements of

the relevant EU directives
