Oxygen Analyzers Introduction

Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. These are used in a variety of measurement scenarios including, but not limited to, boiler trimming in power plants, furnace optimization in refinery and petrochemical applications, process safety in vent headers, and product quality in ethylene production.

oxygen analyzer is a practical and reliable automatic analytical instrument. It can cooperate with various electric unit meters, conventional display recording instruments and DCS distributed control system to quickly and correctly detect and analyze the flue gas content generated by combustion equipment such as boilers, kiln and heating furnaces. . To achieve low-oxygen combustion control, to achieve energy-saving purposes, reduce environmental pollution.

Oxygen Analyzers Feature

• The built-in sensor is convenient for the users to install;

• The built-in sensor temperature-compensation circuit could avoid the influence from the temperature change on the measured accuracy;

• Altitude measurement module can be expanded to avoid the influence from atmospheric pressure change on the measured accuracy;

• The sensor is with no electricity on no consumption, long serving life and easy to maintain for features, etc;;

• No reference gas is needed and the analyzer will not be influenced by oxygen purity in work around atmosphere;

• Imported limiting current sensor is adopted with a rapid response speed, high accuracy and long calibration cycle for features, etc;

• With the functions of built-in compensation and sensor protection, the analyzer can be on power under 99.99% condition without affecting the sensor’s serving life;

• The frame mount installation mode makes it simple and convenient to install;

• With the function of built-in temperature compensation, the sample gas flow wouldn’t bring error to the measurement of the sensor;

• The measured accuracy of the whole range can be met by a random point calibrated, making the operation simple and convenient.

SC: the unit for the oxygen potential migration of the sensor is mV
dIL: 0 — +20.00, linear input zero display value
dIH: 0 — +20.00, linear input full scale display value
Corresponding to dIL~dIH, 7 and 8 pin output current 4~20mA
CC: Heating temperature setting value, when the temperature reaches the set value, the meter automatically stops heating and maintains this temperature.
