Have a critical process that demands accurate measurement of oxygen? 

Measuring oxygen for process control can help ensure that a process is operating efficiently, safely, and with consistent quality. Here are some reasons why measuring oxygen is important for process control:

• Efficiency: In many processes, oxygen plays a critical role in the chemical reactions or combustion processes that occur. By measuring oxygen levels, it is possible to optimize the process to achieve the desired output while minimizing waste or energy consumption.
• Safety: In some processes, the presence or absence of oxygen can pose a safety hazard. For example, in certain chemical reactions, too much oxygen can lead to explosive conditions, while too little oxygen can lead to the formation of toxic byproducts. Measuring oxygen levels can help ensure that the process is operating within safe parameters.
• Quality control: In some industries, the presence or absence of oxygen can affect the quality of the final product. For example, in the production of metals, the presence of oxygen can lead to the formation of impurities that affect the strength and durability of the material. By measuring oxygen levels, it is possible to control the production process and ensure consistent quality.
• Regulatory compliance: In some industries, regulatory bodies require the monitoring and reporting of oxygen levels as part of environmental or safety regulations. By measuring oxygen levels and documenting the results, companies can demonstrate compliance with these regulations.
• Environmental compliance: Oxygen monitoring is essential in industries where the discharge of pollutants into the environment is regulated. For example, in the pulp and paper industry, oxygen levels in wastewater can affect the levels of dissolved oxygen in nearby water bodies, which can have a detrimental effect on aquatic life. By monitoring and controlling oxygen levels, environmental compliance can be achieved, and potential fines and penalties can be avoided.

Our ALPHA OMEGA INSTRUMENTS™ trace and percent oxygen analyzers can measure oxygen for process control by using various measurement techniques such as zirconium oxide, paramagnetic, and electrochemical sensors. These sensors detect the partial pressure of oxygen in the gas or liquid stream and convert it into an electrical signal that is proportional to the oxygen concentration.

To use the analyzer for process control, it must be installed in the process stream, usually through a sample line or a flow cell. The sample is continuously drawn into the analyzer, and the oxygen concentration is measured in real-time. The analyzer provides a signal output, which can be used to control the oxygen concentration in the process by adjusting the flow rates or other process parameters.

In addition, ALPHA OMEGA INSTRUMENTS trace and percent oxygen analyzers can be integrated into control systems such as PLCs (Programmable Logic Controllers) or DCSs (Distributed Control Systems) to automate the process control. This allows for precise control of the oxygen concentration and ensures that the process operates within the desired parameters.

The presence or absence of oxygen can affect the quality of the final product.
