GE Reuter-Stokes RS-FS-9001 is a SiC (Silicon Carbide) UV flame sensor designed

Product Title & Description

Model: RS-FS-9001 The GE Reuter-Stokes RS-FS-9001 is a SiC (Silicon Carbide) UV flame sensor designed for GE Mark VI / Mark VIe gas turbine safety and combustion monitoring systems. It adopts silicon carbide photodiode technology to detect flame ultraviolet radiation, delivering 4–20mA two-wire analog output for flame presence detection. This rugged flame detector is widely installed on gas turbines, boilers and combustion furnaces in power generation, oil & gas and petrochemical industries for burner flame supervision and flame loss trip protection.

Core Product Overview

RS-FS-9001 is a high-performance flame sensor from Reuter-Stokes (GE / Baker Hughes), engineered specifically for harsh combustion environments. Different from traditional GM-tube UV detectors, its SiC photodiode can capture longer-wave UV signals, which can penetrate steam, fog and oil mist in low-NOx combustion applications, greatly reducing false flame loss alarms. The unit uses a hermetically sealed dry argon-filled package with a sapphire optical window resistant to high temperature and pressure. It is a 2-wire loop-powered device combining power supply and 4–20mA signal transmission over the same pair of wires. The sensor automatically adjusts internal gain for wide dynamic flame intensity range without saturation. It feeds real-time flame intensity value to the turbine control system for continuous flame supervision, providing critical safety interlock against flame-out and explosion risk. Optional air or water cooling kits are available for extreme high-temperature mounting positions.

Installation & Configuration Guide

7.1 Pre-installation Preparation

Verify model RS-FS-9001 and inspect sensor housing, sapphire window and threads for damage. Prepare shielded twisted pair 2-wire cable, fitting adapters, cooling accessories (if required) and turbine control system configuration tools. Isolate the burner and lock out power before installation. Avoid scratching the sapphire optical window.

7.2 Standard Installation Steps

Mount the sensor onto the burner viewing port using the correct threaded adapter. Align the optical axis for clear line-of-sight to the flame. Install air or water cooling jacket if operating temperature exceeds 150°C. Run shielded twisted pair cable from sensor to turbine I/O module; connect shield to single-point earth at control cabinet side. Tighten cable glands and fittings to maintain IP65 integrity. Confirm no mechanical stress on sensor body and cable.

7.3 System Configuration & Commissioning

In Mark VI/VIe control software, configure the analog input channel for 4–20mA flame signal. Set flame threshold, flame present / flame loss alarm and trip logic parameters. Perform pre-fire bench check to verify 4–20mA output response. Complete cold commissioning before burner ignition. During commissioning, record flame intensity baseline under normal firing condition. Test flame loss trip function as per turbine safety procedure.

7.4 Maintenance & Precautions

Periodically inspect the sapphire window for soot, dirt or scratches; clean carefully only with approved lens cleaning materials. Check cooling water/air supply and temperature at scheduled outages. Avoid mechanical impact to the sensor and optical window. Do not disassemble the sealed sensor housing, as this will void warranty and break hermetic protection. If false flame loss alarms occur, first inspect window contamination, cooling performance and wiring before sensor replacement.
