Applications
Oxygen is measured in a wide variety
of processes, to confirm its presence
or absence. The most common application
however is measuring oxygen as an 'impurity'
in other gases, e.g. nitrogen generators.
Oxygen is required in aerobic processes and
also in situations that require user intervention,
e.g. to ensure that it is safe to enter a chamber
for maintenance work. Some processes will
only run efficiently in the absence of oxygen,
e.g. furnace atmospheres; others just require
a low level of oxygen for safety reasons, e.g.
inert gas blanketing.

The G1010 oxygen analysers have
numerous applications in processes requiring
the precise measurement of oxygen level. In
ppm or % levels, safe areas or hazardous ones,
in various process conditions and in differing
backgrounds there is a G1010 configuration
right for your needs. Options include a choice
of outputs, AC or DC versions, alternative
oxygen cells or sample conditioning.
Different electrochemical cells are
available to suit the application. The
standard ‘N’ cell has a broad range from high
ppm to 50% oxygen. The ‘L’ cell is designed
for accuracy at low ppm levels, it will also work
at % levels (with a shorter lifetime). The ‘E’ cell
is designed for use in % levels of oxygen
in the presence of mildly acidic gases, e.g.
carbon dioxide, while the ‘H’ cell is perfect for
low ppm oxygen applications where hydrogen
is present. Hitech will be pleased to advise on
which cell is most suitable for an application.

A choice of configuration is available.
The most convenient and economic is a
standard analyser with the cell mounted on
the rear. Alternatively, there is a remote sensor
housing complete with flowmeter and valve.
Where cable lengths and/or hazardous area
conditions are an issue, the transmitter can be
located in the sensor housing.
Different sample conditioning systems
are available, standard or bespoke, according
to the process conditions. Filters, pumps and
regulators can all be incorporated to deliver
the sample in the correct condition. Bypass
flow systems enable longer distances from
process to analyser to be achieved. Hitech
engineers are ready to recommend the right
system for you on receipt of the full gas
stream specification.
For hazardous area applications the sensor
may be mounted remotely in the hazardous
area and safely connected via an MTL zener
barrier to the electronics unit in the safe
area. Alternatively the electronics unit can be
supplied in an EExd enclosure.
