What is a zirconia oxygen analyzer?
AZ100. The zirconia oxygen analyzer AZ100 is designed primarily for small gas- and oil-fired boilers in industry, power, hospitals and ships. It is also used for inert gas generators and oxygen enrichment applications. Deriving combustion efficiency by monitoring flue gas emissions. …
How do you test a zirconia O2 sensor?
How to test an Oxygen Sensor with a Clamp-meter
- Make sure the engine exhaust system is cold.
- Switch the clamp-meter on, to ‘DC current/DC amperage’ mode.
- Put the clamp around either of the oxygen sensor heater power wires (but not both).
- Turn the engine on.
- Observe the reading, which should be between 0.25A and 1.5A.
Why is zirconia used for oxygen sensors?
At high temperatures, zirconia conducts oxygen ions, a characteristic that allows oxygen ions to flow from the high O2 concentration of air to the low O2 concentration on the exhaust side of the ceramic. Since these ions are negatively charged, an electromotive force is produced between the two electrodes.
How does a zirconia O2 sensor work?
Zirconia oxygen sensors are a type of electrochemical sensor. Zirconia dioxide is coated with a thin layer of platinum to form a solid‐state electrochemical fuel cell. Carbon monoxide, if present in the test gas, is oxidized by O2 to form CO2 and thereby triggers the flow of current.
What is an o2 analyzer?
What Is an Oxygen Analyzer? Oxygen analyzers measure the level of oxygen found in a given environment, improving both safety and efficiency in a wide range of industries. These important tools may either measure stack gas or inert gas.
What is the uses of zirconium?
Zirconium(IV) oxide is used in ultra-strong ceramics. It is used to make crucibles that will withstand heat-shock, furnace linings, foundry bricks, abrasives and by the glass and ceramics industries. It is so strong that even scissors and knives can be made from it.
How do o2 sensors work?
Oxygen sensors work by producing their own voltage when they get hot (approximately 600°F). When the outside of the bulb is exposed to the hot gases of the exhaust, the difference in oxygen levels between the bulb and the outside atmosphere within the sensor causes voltage to flow through the bulb.
What is an o2 sensor do?
Every new car, and most cars produced after 1980, has at least one oxygen sensor. Its job is to help the engine keep a certain air-to-fuel ratio that balances power, fuel economy and emissions. The O2 sensor checks the amount of oxygen in the exhaust, compared to the amount in the air.
How does an O2 analyzer work?
An oxygen analyzer measures the para-magnetism of air. The air being measured for oxygen is filtered by passing it through a diffuser before. Then it is passed through the two chambers. One chamber attracts oxygen via its magnetic field, while the other chamber attracts air.
