Honeywell P500 Series Processors

Understanding the Honeywell P500 Series Processor for Industrial Flame Monitoring


In today's industrial landscape, safety and efficiency are paramount. Whether you're operating a chemical plant, an oil refinery, or a power generation facility, maintaining a safe environment is non-negotiable. One critical aspect of ensuring safety is monitoring and controlling combustion processes, and this is where the Honeywell P500 Series Processors for industrial flame monitoring come into play.


What are the Honeywell P500 Series Processors?

The Honeywell P500 Series Processors are advanced industrial flame monitoring solutions designed to enhance safety and optimize combustion processes in various industrial settings. It's part of Honeywell's extensive portfolio of products focused on industrial automation and safety. The Series includes the P522, P531 and P532 Signal Processors, which use S55XBE Series viewing heads.


What are these processors used for?

  1. Flame Detection: The primary purpose of a Honeywell P500 Series Processor is to detect and monitor flames in industrial burners and furnaces. It utilizes advanced flame detection technology to provide real-time information about the presence, quality, and stability of the flame.
  2. Safety: Safety is paramount in industrial settings, especially those involving combustible materials. The P500 Series Processors ensures that burners and furnaces operate within safe parameters. If a processor detects an abnormal flame condition, it can trigger immediate safety shutdowns to prevent accidents and catastrophic incidents.
  3. Efficiency Optimization: Beyond safety, a P500 Series Processor can also contribute to operational efficiency. By continuously monitoring the flame, it helps plant operators make adjustments to optimize combustion, reduce fuel consumption and minimize emissions. This not only improves cost-effectiveness but also ensures compliance with environmental regulations.
  4. Data Logging and Analysis: A P500 Series Processor is equipped with data logging capabilities, allowing plant operators to record and analyze historical flame data. This information is invaluable for performance analysis, troubleshooting, and maintenance planning.


When Do You Need a Honeywell P500 Series Processor?

  1. Highly Combustible Processes: If your factory or plant involves highly combustible materials such as natural gas, coal, oil, or petrochemicals, a Honeywell P500 Series Processor is essential. It ensures that flames remain stable and within safe boundaries during combustion.
  2. Critical Processes: In industries where downtime can result in substantial financial losses or safety hazards, such as power generation, chemical manufacturing, and oil refining, a P500 Series Processor is a crucial tool for preventing unplanned shutdowns and ensuring uninterrupted operations.
  3. Stringent Safety Regulations: If your facility is subject to strict safety regulations and compliance requirements, the P500 Series Processor can help you meet these standards by providing reliable flame monitoring and safety shutdown capabilities.
  4. Emissions Control: If your plant is committed to reducing emissions and meeting environmental regulations, the P500 Series Processor can assist in optimizing combustion for minimal emissions while maintaining process efficiency.


In conclusion, the Honeywell P500 Series Processor is an indispensable tool for plant operators in various industrial settings. Its ability to monitor and control flames not only ensures safety but also contributes to operational efficiency and compliance with environmental regulations. If your factory deals with highly combustible materials, critical processes, stringent safety standards, or emissions control, you're probably using a Honeywell P500 Series Processor as a wise decision that can safeguard your operations and your reputation.

Honeywell P500 Series Processors

Honeywell P500 Series Processors, including the P522, P531 and P532 have dual capabilities; therefore, they are able to detect UV & IR (InfraRed).


  • UV is used for clean burns such as natural gas.
  • IR is used for dusty or smokey areas such as coal or oil.

Applications for Honeywell P500 Series Processors

Honeywell P500 Series Processors are often used in these types of situations:


  • Places where they have discrimination or flame detection issues
  • Places where dual capabilities are needed, such as a need for detecting both UV & IR (InfraRed)
  • Where a system is not adversely affected by X-ray and gamma rays
  • Multi-Fuel Applications such as a facility that wants to burn gas & oil or a facility that burns coal & gas

Why do you need a Scanner?

If there is no scanner and the flame goes away then an explosive environment can easily be created if the end user doesn’t turn off the fan.
