The electrical, mechanical, temperature, and environmental specifications above are reported by a technical reference for the RS-FS-9001 / 362A1052P404 combination.

Functional Description

The flame detector continuously monitors optical radiation from the combustion zone. When a flame is present, the sensor generates a corresponding analog signal for the connected burner-management or turbine-control system.

Its fast response is particularly important for flame-out detection. If combustion is lost, the control system can use the detector signal to initiate the appropriate fuel shutoff or protective sequence.

The RS-FS-9001 is therefore a field flame sensor, not a PLC input card. The 4–20 mA signal allows it to interface with compatible control-system analog inputs.

Typical Applications

Gas turbine flame monitoring
Industrial burners
Boiler combustion systems
Furnace flame monitoring
Burner Management Systems (BMS)
Power-generation equipment
Process-heating systems
Industrial combustion control

Installation & Configuration

Verify RS-FS-9001 / 362A1052P404 against the existing detector.
Confirm the required hazardous-area certification.
Check the sensor mounting thread and mechanical installation.
Inspect the sapphire viewing window.
Connect the approved 5-pin electrical connector.
Verify 12–30 VDC supply, normally 24 VDC.
Connect the 4–20 mA output to the compatible control-system input.
Align the detector with the combustion/flame zone.
Perform flame-present and flame-out signal checks.
Confirm the BMS or turbine controller responds correctly.

Commissioning Checklist

Verify model and part number
Check sensor housing
