GAS 222.31 AMEX
1 Introduction
1.1 Intended Use
The sample gas probe is intended for installation into gas analysis systems in commercial applications.
Sample gas probes are among the main components in a gas conditioning system.
– Therefore also note the related drawing in the data sheet in the appendix.
– Before installing the device, verify the listed technical data meet the application parameters.
– Further verify all contents are complete.
Please refer to the type plate to identify your model. In addition to the job number/ID number, this also contains the article
number and model designation.
Please note the specific values of the device when connecting, and the correct versions when ordering spare parts.
Passing through gases
Flammable gases above the UEL may only be blown back with inert gases. Flammable gases from 25% LEL and up to the UEG
may be blown back provided the operator ensures the blown back gas is not and cannot be explosive. For safety reasons we re-
commend only using inert gases in these cases as well.
Blowing back explosive atmospheres (range from UEG to OEG) with the probes is prohibited due to possible adiabatic compres-
sion (high blowback pressure against contaminated filter). The operator is responsible for compliance with these conditions tak-
ing into account his risk assessment.

2.2 General Hazard Warnings
The maximum surface temperature of the probes solely varies by operating conditions (steam temperature, sample gas inlet
temperature, ambient temperature, fluid flow rate). For use in explosive areas please particularly note the related hazard warn-
ings.
The equipment must be installed by a professional familiar with the safety requirements and risks.
Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent
malfunctions and avoid personal injuries and property damage.
The operator of the system must ensure:
– Safety notices and operating instructions are available and observed,
– The respective national accident prevention regulations are observed,
– The permissible data and operational conditions are maintained,
– Safety guards are used and mandatory maintenance is performed,
– Legal regulations are observed during disposal,
– compliance with national installation regulations.
Maintenance, Repair
Please note during maintenance and repairs:
– Repairs to the unit must be performed by Bühler authorised personnel.
– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.
– Always use genuine spare parts.
– Do not install damaged or defective spare part. If necessary, visually inspect prior to installation to determine any obvious
damage to the spare parts.
Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.
DANGER Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
DANGER Toxic, corrosive gas/condensate
Sample gas/condensate may be hazardous to health.
a) If necessary, ensure a safe gas/condensate discharge.
b) Always disconnect the gas supply when performing maintenance or repairs.
c) Protect yourself from toxic/corrosive gasses/condensate when performing mainten-
ance. Wear appropriate protective equipment.
DANGER Explosion hazard
Life and explosion risk may result from gas leakage due to improper use.
a) Use the devices only as described in this manual.
b) Regard the process conditions.

GAS 222.31 AMEX
DANGER Danger to life and explosion during installation and maintenance
The unit must not be worked on (assembly, installation, maintenance) in explosive at-
mospheres.
DANGER
Use in explosive areas
Flammable gasses and dust could ignite or explode. Avoid the following hazard sources:
Application area!
Never operate the gas probe outside the specifications. Extracting gases or gas mixtures
which are also explosive in the absence of air is prohibited.
Electrostatic charge (sparking)!
The equipment may only be used where normal operating conditions do not frequently
produce flammable, electrostatic discharge.
Always clean plastic housing parts and decals with a damp cloth.
Sparking!
Protect the equipment from external blows.
Flame propagation!
If the process holds a risk of flame propagation, install a flame arrestor.
Adiabatic compression (explosion hazard)
Adiabatic compression may cause high gas temperatures during blowback. Never blow-
back if gases are explosive. Only use nitrogen (inert gas) to blowback flammable gas.
Dust:
If possible, take the electrical components which must be opened for repair to a dust-
free room. If unable to do so, prevent dust from entering the housing.
Ignition of dust layers!
When using the device in a dusty environment, routinely clean dust from all compon-
ents.
The ignition temperature resp. smouldering temperature of flammable dusts resp. dust
layers present must be considerably higher than the maximum surface temperature of
the probe (observe applicable standards and statutory regulations).

3 Transport and storage
Only transport the product inside the original packaging or a suitable alternative.
The equipment must be protected from moisture and heat when not in use. They must be stored in a covered, dry and dust-free
room at a temperature between -20°C to 50°C (-4°F to 122°F).

4 Installation and connection
4.1 Installation site requirements
Sample gas probes are intended for flange mounting.
– Installation site and installation position are determined based on requirements specific to the application.
– If necessary, the connection piece should be slightly tilted toward the centre of the channel.
– The installation site should be protected from the weather.
– In addition, adequate and safe access for installation and future maintenance work should be provided. Particularly follow
the uninstalled size of the probe tube!
If the probe is transported to the installation site in pieces, it will first need to be assembled.
4.2 Installation
DANGER Danger to life and explosion during installation and maintenance
The unit must not be worked on (assembly, installation, maintenance) in explosive at-
mospheres.
DANGER Explosion hazard
When used in explosive areas
Flammable gasses and dust could ignite or explode.
Never operate the gas probe outside the specifications. Extracting gases or gas mixtures
which are also explosive in the absence of air is prohibited.
DANGER Explosion hazard due to ignition of dust
When using the device in a dusty environment, routinely clean dust from all compon-
ents.
The ignition temperature resp. smouldering temperature of flammable dusts resp. dust
layers present must be considerably higher than the maximum surface temperature of
the device (observe applicable standards and statutory regulations).
If possible, take the electrical components which must be opened for repair to a dust-
free room. If unable to do so, prevent dust from entering the housing.
DANGER Explosion hazard due to flame propagation
Severe injuries and damage to the system
If the process holds a risk of flame propagation, install a flame arrestor.
4.3 Installing the Inlet Filter
The inlet filter, if necessary with matching extension, must be screwed in. The probe is then attached to the mating flange using
the included seals and screws.
4.4 Insulation
On heated probes completely insulate any exposed flange areas and, if applicable, the connection piece to absolutely prevent
thermal bridges. The insulating material must meet the application requirements and be weatherproof.
