Theory of measurement
The cubic system solid solution prepared by adding calcia (CaO), yttria (Y2O3), etc. tozirconia (ZrO2) is a solid electrolyte (sensor cell) transmitting oxygen ion (O2-) athigh temperature. When electrodes (porous) are equipped both sides of the solid
electrolyte and gases of different oxygen concentrations are placed on each electrode,
oxygen ion transmission occurs and an electromotive force is generated between theelectrodes.

The relationship between the electromotive force of the sensor cell and oxygen concentration
is expressed by the following equation:

Oxygen concentration in sample gas, PO2(S), can be derived from this equation by measuring
the cell electromotive force (EMF).
The SH- Ⅳ D type O2 Analyzer includes this solid electrolyte (sensor cell) in the sensor
device of the transmitter and the cell is heated to a constant temperature (850 ℃ ) with aheater.

The sample gas is pressed into GAS IN and contacts to the sensor cell and generates

a cell electromotive force (EMF) corresponding to the oxygen concentration in the sample gas.
This electromotibe force is operated by the digital circuit in the Analyzer and displayed andoutput as the directly-readable oxgen concentration (vol%).

Method of installation
2-1

Condition of installation site
Since there is a fear of gas poisoning and oxygen deficiency,
pipes at the entrance and exit for the gas must be constructedwithout any leaks.
Route the gas outlet at a safe placeprovided with the atmospheric pressure.
・ Low in mechanical vibration.

!

CAUTION・ Low in concentration of corrosive gases (F, HF, C1, HC1, SO2, H2S, etc.).
・ Place where silicone rubber packing or silicone tube in not used.
・ Little temperature change and near ambient temperature.
・ No direct high radiation of heat.
・ Little effect of electric noise・ Low in moisture and dust.

Note the following points for measuring gas used with this analyzer.
・If the measuring gas contains corrosive gases (e.g. F, HF, C1, HC1, SO2, H2S), thesensor cell may deteriorate in a short time.

・

If the measuring gas contains toxic substances (e.g. Si, Pb, P, Zn, Sn, As), thesensor cell may deteriorate in a short time.

・ A large quantity of Si, in particular, can be generated when siliceous material(e.g. paint, mold removal aids, packing, piping material) is heated.
Before the initial start-up of the furnace or the first start-up after repair work,
detach the analyzer and heat the empty furnace sufficiently.
・If the analyzer is used in an environment that may generate corrosive gases or
toxic substances, the use of an activated carbon filter or the like is recommended.

PipingCAUTION!

Since there is a fear of gas poisoning and oxygen deficiency,
pipes at the entrance and exit for the gas must be constructedwithout any leaks.
Route the gas outlet at a safe placeprovided with the atmospheric pressure.

The piping is extremely important for obtaining a correct measurement. Note thefollowing before doing piping.
① Material of pipes
・Using the ppm range:

Use copper or stainless steel pipes.

・

Using the % range:

Organic material such as Teflon, Viton, vinyl, and nylon
can be used.

Note ） ・When organic material is used, select a material that will withstand thetemperature of the introduced measuring gas.

・

Silicon tube lets the oxygen in the air penetrate, thus increasing theindication value.
The use of siliceous piping or packing may cause the sensor to deteriorate
in a short time. Therefore, never use a silicon tube or silicon packing.

② Oil elimination from metal piping
・

Clean the inner surface of copper or stainless steel pipes of oil or organic
substances using a volatile cleaning solvent or the like, and then thoroughly
purge using N2 gas or air.

Note) Oil or organic substances attached in the inner surface of metal pipes gradually
mix into the measuring gas and burn in the vicinity of the heated sensor, thus
reducing the indication value.
③ Do not provide a gas pocket in the piping.
・ Do not provide a large container in the piping.
・ Make the piping as short as possible and with a simple structure.
Note) Having a large gas pocket (filter or activated carbon filter) or having a longpipe will prolong the time required to replace the measuring gas, thusincreasing wasted time and the response time.

Make the gas pocket as small as

possible and the pipes as short as possible.
④ Elimination of corrosive gas
・

For F, HF, C1, HC1, and SOx[A] Take note of the service life of activated carbon.
[B] Take note of the dissolved oxygen in water when washing in it.

⑤ Removal of liquid in piping
・ When the dew point of the gas to be measured is higher than the ambient
temperature:
Provide a trap or electronic cooler in the piping to remove the liquid.
Lay the draining pipe slanting downwards so that the liquid can flow smoothly.
⑥ Building a standard gas bottle into the piping will be convenient for gas calibration.

4-3 Gas calibration
Gas calibration is necessary for maintaining the measurement accuracy.
Perform gas calibration at the start of operation and then monthly after that.
Note) Gas calibration has been performed according to the customer’s range specifications
before shipping and that calibration gas concentration has been set as the initialvalue.
When the number of calibration gases and gas concentrations deviate from thecustomer’s specifications, it is necessary to change the calibration gas
concentration before performing calibration.
4-3-1 Selection of calibration gas
When gas is to be provided by the customer, refer to the following table forselection of the calibration gas concentration and the number of gas bottles.
For accuracy, ZERO and SPAN calibrations of each measuring range are desirable.
Refer to the following standard for the corresponding measuring range and ZERO gas
concentration or SPAN gas concentration.
ZERO gas concentration = Corresponding measuring range 5 - 20% FS
SPAN gas concentration = Corresponding measuring range 80 - 95% FS
When the SPAN gas concentration of the low concentration measuring range is very
close to the ZERO gas concentration of the high concentration measuring range, one
concentration can be used for both. In this case, use the SPAN gas concentration
setting of the low concentration measuring range and set NON as the ZERO gas
concentration setting of the high concentration measuring range.
Values in ( ) are recommended for more accurate calibration.

When the number of calibration points must be reduced with consideration for the gas
bottle (e.g. reducing the 4-point calibration to 3-point calibration), it isnecessary to cancel the setting for the unused calibration gas concentration andcorresponding memory data.
To cancel such a setting, set NON for the unused calibration gas concentration. When
you neglect this cancellation procedure and perform the calibration with the unusedsetting value, correct measurement may not be obtained.
The same operation must be performed when the customer’s number of calibration points
is different from the number of calibration points that have been set before shipping.
