Well-designed High Precision Oxygen Sensor - Nernst N2032 oxygen analyzer – Litong

Application range

The Nernst N2032 oxygen analyzer can directly monitor the oxygen content in the flue gas during or after the combustion of boilers, furnaces, and kilns.

Application characteristics

After using the Nernst oxygen analyzer, users can reduce a lot of energy consumption, control environmental pollution, ensure safe production and extend the service life of the equipment, and recover all investment in a short time.

The process of controlling the peroxygen combustion can reduce a large amount of energy consumption. An oxygen analyzer can be used to control the ratio of fuel to air, so that the fuel is fully burned while avoiding the large amount of heat that is taken away by the peroxygen combustion and reducing COx, SOx, and NOx emissions produced by peroxygen combustion can effectively reduce environmental air pollution.At the same time, the damage of carbonic acid, sulfuric acid and nitric acid produced by the mixing of such harmful gases with water to boiler pipeline equipment can also be controlled.

The use of oxygen analyzer can generally save 8-10% of energy consumption.

Technical characteristics

• Two probes measurement: One analyzer with two probes can save installation costs and improve reliability.

• Multi-channel output control: The analyzer has two 4-20mA current output and computer communication interface RS232 or network communication interface RS485

• Measurement range: The oxygen measurement range is 10^-30 to 100% oxygen.

• Alarm setting: The analyzer has 1 general alarm output and 3 programmable alarm outputs.

• Automatic calibration: The analyzer will automatically monitor various functional systems and automatically calibrate to ensure the accuracy of the analyzer during measurement.

• Intelligent system: The analyzer can complete the functions of various settings according to the predetermined settings.

• Display output function: The analyzer has a strong function of displaying various parameters and a strong output and control function of various parameters.

• Safety function: When the furnace is out of use, the user can control to turn off the heater of the probe to ensure safety during use.

• Installation is simple and easy: the installation of the analyzer is very simple and there is a special cable to connect with the zirconia probe.
