Working Principle Of Wall-mounted In-line Zirconia Probe Sensor

The wall-mounted zirconia oxygen sensor is a high-temperature electrolyte concentration battery. In a high-temperature environment of hundreds of degrees, it has conductive properties that can produce oxygen ion migration. Because the measured gas (flue gas or other gases) and the reference gas (air Or other gases) The oxygen partial pressure of the platinum electrodes on both sides of the In-line oxygen probe sensor is different. A certain number of oxygen ions migrate between the two electrodes to generate an oxygen concentration difference potential. The relationship between the potential value and the oxygen concentration can be used Nernst formula to express:

E=RT/4FxLnP1/P2

In the formula: E-- Oxygen concentration difference potential (V)

R--ideal gas constant (8.314J/moLK)

T--Absolute temperature value (K)

F--Faraday's constant (96500c/moL)

P1--Reference gas partial pressure (air)

P2 - measured gas partial pressure

The oxygen sensor wall mounted transmitter calculates and converts the measured data through the microcontroller, displays the oxygen content on the digital tube, and converts it into a current signal for use by a computer or recorder.

SOLIDAT wall mounted o2 sensor is not only used in high-energy-consuming industries such as steel, electric power, petroleum and petrochemicals, kilns, paper and pulp, food, fiber, etc., but is also used for combustion in various combustion equipment such as waste incinerators and small and medium-sized boilers. Management or control, it has a wide range of uses and has achieved fruitful results in energy saving. In addition, oxygen sensor wall mounted can also completely burn substances through oxygen concentration management and control, reducing emissions of carbon dioxide, SOx and NOx, and contributing to preventing global climate change and preventing air pollution.
