Honeywell S700 and S800 Flame Scanner Series Processors and Viewing Heads

The S700/S800 Platform at a Glance

The Honeywell S700 and S800 Self-Checking Series is the lowest-cost optical flame monitoring solution in the IFM product line, and for a wide range of single-burner and fixed-fuel multi-burner applications, it does exactly what you need at a price that fits a tight maintenance budget.

The platform combines 700 Series signal processors with the S70X and S80X Series viewing heads. The viewing head can be located up to 1,300 feet from the processor, which makes this platform well suited to installations where the control room is far from the burner front.

Processors

• 700ACSP — AC-powered signal processor for single-burner applications.
• 700DCSP — DC-powered equivalent, commonly used where plant power infrastructure favors 24VDC systems.

Viewing Heads

• S702 / S702PF — Standard UV viewing head for single-burner applications. PF variant adds purge-and-proving functionality.
• S706 / S706PF — Multi-spectral viewing head for more demanding sensing environments. PF variant includes purge-and-proving.
• S802 / S806 — The S800 Series heads add enhanced ambient temperature ratings and are the preferred choice in high-heat environments such as steam reformers or airgas plant applications.
  

When to Choose the S700/S800 Platform

Plant engineers typically reach for the S700/S800 platform in these situations:

• Single-burner configurations where a full P500 Series processor is more capability than the job requires.
• Multi-burner applications where fuel type is fixed and the flame envelope does not shift significantly between burners.
• Installations where budget is the primary constraint; this is the most cost-effective Honeywell IFM optical solution available.
• Locations with limited burner-front space; the bullet-type sensor requires minimal clearance.
• Environments with high ambient temperatures, wash-down exposure, or significant vibration.
• Premix gas and Lo-NOx burner applications, where UV sensing provides reliable flame detection.

Key Features

• Standard Modbus communications integrates cleanly with existing DCS and SCADA systems.
• Adjustable amplification and gain lets you tune sensitivity for low flame signal conditions.
• Redundant 24VDC power input; backup power keeps the system running if the primary supply drops.
• Single configuration file simplifies commissioning and ongoing maintenance.
• Intuitive interface: straightforward to operate even for technicians new to Honeywell IFM systems.
  

• Midstream oil and gas plants: storage, processing, and pipeline facilities
• Steam reformers operating at high ambient temperatures
• Airgas and industrial gas facilities requiring cost-effective, rugged solutions
• Tissue paper plants and other manufacturing facilities with air heater burners
• Duct burners inside combined cycle power plants:  compact footprint, remote interface, low cost
