Description
Product Introduction
Reliable flame detection is critical on gas turbines, especially with water or steam injection and liquid fuels that can obscure traditional UV signals. The GE RS-FS-9001 (GE part 362A1052P004) is a silicon-carbide (SiC) photodiode Flame Tracker sensor that delivers a continuous 4–20 mA signal proportional to flame intensity.
The SiC sensor detects longer-wavelength UV components that penetrate fuel, water and steam fog better than Geiger-Mueller tubes. It mounts via ¾-inch NPT, operates on 12–30 VDC, and withstands high vibration and process pressure. Optional water or air cooling extends ambient temperature capability.

Installation & Configuration Guide
Phase 1 — Pre-Installation (est. 10–15 min)
Isolate the turbine and follow lock-out/tag-out and hot-work procedures. Tools: appropriate wrenches, torque wrench, multimeter, ESD protection if handling electronics. Record existing sensor orientation, cooling arrangement and cable part number. Photograph the mounting location, cooling coil (if used) and connector.
Phase 2 — Removal (est. 10–15 min)
Disconnect the electrical connector (MIL-C-38999 style). If a water-cooling coil is fitted, isolate and drain the cooling circuit. Unscrew the sensor from the ¾-inch NPT port. Cap the process opening and protect the sapphire window.
Phase 3 — Installation (est. 10–15 min)
Inspect the new sensor window for cleanliness. Apply appropriate thread sealant, install the sensor (and cooling coil/can if required), and torque to specification. Reconnect the cable and cooling lines. Verify polarity on the 4–20 mA loop.
Phase 4 — Power-On & Testing (est. 15–20 min)
Apply 12–30 VDC. Confirm resting current is in the expected no-flame range (typically ~3.7–4.1 mA). Observe flame-on response during light-off or test flame. Check for open/short diagnostics and stable 4–20 mA signal at the controller. Log the change.
Troubleshooting quick-reference:
- Low or zero current → check power, polarity and cable continuity
- No response to flame → clean sapphire window or verify line-of-sight
- Over-temperature → confirm cooling flow or air velocity
