Description
1. Product Overview
GE RS‑FSM‑1002‑002 is an industrial‑purpose flame‑scanner module manufactured by Reuter Stokes under GE (General Electric). It acts as a core supporting detection unit for combustion‑control systems of gas turbines and thermal‑power boilers, and is developed for combustion monitoring, flame‑status judgement and furnace‑safety‑supervision scenarios of large‑scale power equipment.
Integrating voltage‑to‑frequency conversion, adjustable‑comparator logic operation, signal shaping output and isolated signal transmission, this module is a critical hardware card of the Furnace Safety Supervision System (FSSS). It is mainly used to monitor the real‑time flame status inside boiler and gas‑turbine combustion chambers, accurately judge flame presence/absence and flame‑signal intensity, and prevent safety accidents caused by flame‑out‑induced deflagration and air‑fuel‑ratio imbalance.
Optimized for mainstream GE MK‑series gas‑turbine controllers, the hardware adopts a partition‑isolated power‑supply design: the input circuit is powered by isolated protective power while the output circuit uses grounded power supply, delivering excellent condition adaptability and operational stability. Validated under harsh industrial environments, the module is vibration‑proof and highly immune to electromagnetic interference. It supports 7×24‑hour non‑stop operation inside gas‑turbine and boiler control cabinets exposed to high temperature, dust and strong EMI. Widely deployed in combustion‑safety‑monitoring projects for thermal‑power plants, gas‑turbine units and combined‑heat‑and‑power facilities, it serves as an essential detection device for safety interlock, fault‑protection and stable operation of industrial combustion systems.
2. Core Functions
High‑precision real‑time flame‑status monitoring and judgement: Equipped with a dedicated flame‑signal acquisition and processing unit, the module precisely captures sensing signals from the combustion chamber. By comparing signal amplitudes against preset thresholds via its adjustable comparator, it reliably identifies flame‑on, flame‑off and abnormal‑flame conditions, achieving round‑the‑clock furnace‑flame monitoring and providing core decision‑making data for combustion‑system safety interlocks.
Dual‑mode standard‑signal output compatibility: A dual‑channel output architecture supports both logic‑level output and frequency‑signal output. The open‑collector grounded logic output provides discrete feedback of flame status: low‑level for Flame‑On and high‑level for Flame‑Off. The built‑in voltage‑to‑frequency converter generates standard frequency‑based signals to meet data‑acquisition requirements of different GE gas‑turbine controllers.
Seamless compatibility with full‑range GE gas‑turbine controllers: Natively compatible with GE MK I, MK II, MK IV and MK V gas‑turbine controllers. Direct connection to the unit’s main control system is possible without additional signal‑conversion hardware, enabling fast flame‑signal transmission, status feedback and interlock coordination with the complete GE gas‑turbine control architecture.
Adjustable‑threshold precision calibration: The core adjustable‑comparator circuit allows on‑site customization of detection thresholds. Flame‑sensitivity can be fine‑tuned according to combustion conditions, fuel types and furnace environments, effectively preventing false or missed judgements caused by ambient light interference, dust coverage and signal drift, thus ensuring reliable flame detection.
Partition‑isolated power‑supply anti‑interference design: Independent power‑supply circuits are deployed for input and output loops. The signal‑input side uses isolated protective power while the output side adopts a grounded power supply. This architecture eliminates power‑supply crosstalk, voltage transients and line‑borne noise, improves signal stability under complex electromagnetic conditions and prevents signal distortion and false detections.
Combustion‑system safety‑interlock protection support: Real‑time flame‑status and detection data are uploaded to cooperate with the FSSS furnace safety supervision system. Functions including flame‑trip interlock shutdown, abnormal‑flame alarm and combustion‑fault protection can be triggered in advance to mitigate major hazards such as furnace deflagration, fuel accumulation and fuel leakage, and safeguard gas‑turbine and boiler units.
- Long‑term maintenance‑free industrial‑grade stable operation: Reinforced circuitry and streamlined hardware with no moving wear‑prone components deliver high‑temperature resistance, vibration resistance and EMI immunity. The module adapts to harsh high‑temperature, dusty workshop environments, supports long‑term uninterrupted unit operation, features an extended maintenance‑free service cycle and reduces on‑site O&M costs.

4. Working Principle
The GE RS‑FSM‑1002‑002 flame‑scanner module operates under a closed‑loop workflow: flame‑signal acquisition → threshold comparison & calculation → signal conversion & conditioning → dual‑mode output → system interlock coordination.
Through its isolated‑power input circuit, the module continuously acquires raw detection signals transmitted by furnace flame sensors. An on‑board adjustable comparator compares the measured signal amplitude with the preset threshold to determine whether flame combustion is active inside the furnace.
After flame‑status evaluation, two parallel output channels send feedback signals simultaneously. The open‑collector grounded logic circuit outputs high‑/low‑level discrete signals indicating Flame‑On or Flame‑Off. Meanwhile, the voltage‑to‑frequency converter transforms analogue measurement data into standard frequency signals matching the signal‑acquisition logic of GE MK‑series main controllers. The independently‑powered grounded output circuit isolates upstream interference and guarantees clean, stable outgoing signals.
During unit operation, cyclic flame monitoring continues. Once flame loss, signal anomaly or flame interruption is detected, an alarm signal is immediately transmitted to the furnace safety supervision system and gas‑turbine main controller. Protection actions such as alarm triggering, fuel shut‑off and interlocked shutdown are activated to prevent furnace deflagration, fuel leakage and equipment damage, ensuring safe, compliant and stable combustion‑system performance.
5. System‑Architecture Compatibility
GE RS‑FSM‑1002‑002 is an OEM dedicated flame‑detection module for GE gas‑turbine control systems.

It seamlessly interfaces with flame sensors, unit main controllers, SCADA supervisory platforms and interlock‑protection loops, independently completing the full workflow of flame detection, signal transmission and status feedback. Its standard form factor fits original‑equipment cabinet slot layouts with simple, universal wiring. It can be integrated into new gas‑turbine and boiler projects or directly replace faulty legacy flame‑scanner modules during control‑system retrofits, delivering low replacement costs, broad interoperability and high post‑retrofit operational stability.
