Detailed information on the German MESA in-line oxygen probe:

The German MESA zirconia probe is a measuring element that uses zirconia ceramic sensitive elements to measure the oxygen potential in various heating furnaces or exhaust pipes. The corresponding oxygen concentration is calculated based on the principle of chemical equilibrium, achieving monitoring and control of the combustion air-fuel ratio in the furnace, ensuring product quality and exhaust emissions standards. Through it, automatic control of the combustion process in industrial heating furnaces and product quality control of parts in controllable atmosphere furnaces for heat treatment can be achieved. It can be used for atmosphere control in industrial sectors such as metallurgy, chemical industry, power, ceramics, automotive, and environmental protection for the following occasions.
Boiler: Various forms of boilers that use various fuels such as coal, oil, gas, etc., such as power generation boilers, steam boilers, etc.
Heating furnace: Various forms of furnaces that use coal, oil, and gas as fuels, including heat treatment heating furnaces, glass firing furnaces, etc.
● Rotary kiln: including ore sintering kiln, cement firing kiln, aluminum ore processing sintering kiln, etc.
Incinerators: including industrial incinerators, civilian incinerators, toxic and harmful substance incinerators, etc.
It is currently the best combustion atmosphere measurement method, with advantages such as simple structure, rapid response, easy maintenance, convenient use, and accurate measurement. The use of this sensor for measuring and controlling combustion atmosphere can not only save fuel energy, but also stabilize and improve product quality, shorten production cycles, and enhance furnace safety.

MESA oxygen probes are divided into direct insertion oxygen probes and sampling oxygen probes.
The direct insertion oxygen probe (model: MF160.39.09.0) is a device that directly inserts zirconia into a high-temperature gas to detect the oxygen content in the gas. This detection method is applied to the temperature range of 700-1050 ℃ in the tested atmosphere, using the high temperature of the tested atmosphere to reach the working temperature of zirconia without the need for an additional heater. High detection accuracy, fast response speed, and minimal maintenance. In addition, MESA adopts the most advanced connection method internationally, which is to weld zirconia and alumina tubes together, successfully solving the high-temperature sealing problem of ceramic materials and achieving excellent sealing performance.

According to different cost prices, MESA oxygen probes have three different structures for users to choose from:

*The type is a zirconia element that is sealed on one side and bonded or welded to an alumina ceramic tube. The inside is the reference gas, the outside is the furnace atmosphere, and oxygen ions migrate through the ceramic.
The second type has a zirconia sphere
The third type is a continuous, enclosed, and compact zirconia tube, equipped with an S-type thermocouple.

The third type of oxygen probe is a unique product of MESA, with much higher accuracy and lifespan than the other two.

Several major application environments and their effectiveness:
1、 Industrial boilers and heating furnaces: By measuring the oxygen content in flue gas, the combustion system can be controlled to achieve low oxygen combustion, reducing heat loss and saving energy. Practice has proven that reducing the oxygen content in flue gas from 3% to 1% can reduce exhaust losses by 24% and save fuel by 8%.
2、 Controlled atmosphere furnace for heat treatment: The oxygen level in the atmosphere inside the heat treatment furnace is measured by an oxygen probe, and the corresponding carbon potential is calculated based on the chemical equilibrium principle of the atmosphere inside the heat treatment furnace to monitor or control the carbon potential inside the furnace. In this regard, the benefits brought by oxygen probes are significant.
Firstly, the improvement of product quality has essentially eliminated waste products; Secondly, it shortened the carburizing time, reduced the consumption of carburizing agents, and saved energy.
Practice has proven that using oxygen probes can shorten working hours by 20% and reduce the consumption of penetrating agents by 50-70%; And it can avoid the formation of carbon black, reducing the cleaning work.
3、 Ceramic kiln: Controlling the furnace atmosphere through an oxygen probe not only saves energy and reduces pollution, but also improves product quality. If a glaze containing a small amount of copper oxide is sintered in three different reducing atmospheres controlled by an oxygen probe, three different colors can be obtained: light green in a light reducing atmosphere; It appears light brown in a moderate reducing atmosphere and light red in a heavy reducing atmosphere. Practice has proven that using an oxygen probe to control the atmosphere is an important means of ensuring the quality of ceramics.
