Lamtec FFS08 Flame Sensor for Burner Flame Monitoring
Overview
The Lamtec FFS08 is a non-compact flame sensor designed for safety-critical flame monitoring on industrial burners, mounted orthogonally to the flame axis for flexible installation on a wide range of firing systems. Available in ultraviolet (UV) and infrared (IR) spectral variants, the FFS08 detects the optical radiation emitted by a stable flame and passes this signal to the LAMTEC F152 evaluation unit or a compatible burner management system such as the CMS or ETAMATIC, which continuously verifies flame presence and initiates burner shutdown if the flame signal is lost.
Seven Star LLC supplies the Lamtec FFS08 as an authorized partner of Lamtec, supporting combustion safety and burner management upgrades for power plants, process heaters, and industrial boiler installations across Muscat, Sohar, Salalah, and the wider Sultanate of Oman. Genuine Lamtec flame sensors, evaluation units, and burner management components are available through Seven Star LLC for new-build and retrofit combustion safety projects throughout the GCC.
Measurement and Operating Principle
The FFS08 uses optical radiation detection to continuously verify that a burner flame is present and stable. UV-sensitive variants respond to the ultraviolet radiation characteristic of open flames from natural gas and light fuel oil, while IR-sensitive variants respond to infrared radiation and flicker frequency, suited to fuels and flame types where UV signal strength is weaker. The sensor’s optical signal is transmitted to the F152 evaluation unit, which analyzes signal strength and flicker characteristics against SIL 3 safety logic to distinguish a genuine flame from background radiation, hot refractory glow, or other false-positive sources.
Because the FFS08 operates in continuous mode, it is suited to applications requiring ongoing flame supervision throughout the burner firing cycle, rather than intermittent pilot-only monitoring. The evaluation unit’s SIL 3 safety rating, certified to DIN EN 61508 and DIN EN 298, ensures that a genuine loss-of-flame condition results in a rapid, fail-safe burner trip, protecting against unburned fuel accumulation and potential explosion hazards in the furnace or combustion chamber.
Each FFS08 variant is tuned to a specific optical acceptance angle to match the flame geometry it must reliably see: approximately 5° for the UV-1, 10° for the UV-4, 20° for the UV-6, and a wider 60° field of view for the IR variants, letting the specifying engineer match sensor selectivity to burner design and furnace geometry. Minimum usable signal output is specified at greater than 25 mVAC for UV variants and greater than 10 mVAC for IR variants, with a minimum flicker frequency of approximately 7 Hz used by the F152 evaluation unit to help distinguish a genuine modulating flame from steady background radiation. The sensor draws 24 to 42 VDC at no more than 20 mA and connects via a shielded six-conductor cable (6 x 0.34/0.5 mm²) that can run up to 300 meters to the evaluation unit, supporting flame sensors mounted well away from the control room on large boiler fronts.
Engineering Design of the Lamtec FFS08
The FFS08 is housed in a robust nickel-plated brass (EN CW614N) cylindrical body with a threaded optical viewing window at the sensing end and a cable gland connection at the mounting end, built to withstand the vibration, heat, and dust conditions typical of burner fronts in industrial boiler and process heater installations. The sensor is approved for safe-area use and is available in multiple spectral configurations (UV-1, UV-4, IR-1, IR-1 T, IR-1 T/S2) to match the flame characteristics of natural gas, light fuel oil, and other single- or multi-fuel combustion applications.
Mounting accessories, including the FS60-00 and FS60-10 brackets and the FS65 cooling air housing, allow the FFS08 to be positioned at the optimal viewing angle relative to the flame while protecting the sensor from excessive furnace radiant heat. The FFS08 pairs with LAMTEC’s F152 evaluation unit for standalone flame monitoring installations, or integrates directly with LAMTEC’s CMS combustion management system and ETAMATIC burner controls for fully integrated combustion safety and control architectures, simplifying wiring and commissioning on new burner management system projects.
The standard Lamtec FFS08 weighs approximately 0.40 kg complete with its 3 m connection cable and reaches a maximum immersion depth of 65 mm into the burner front, while the longer FFS08 L variant weighs approximately 0.55 kg, extends to a 150 mm immersion depth for recessed or refractory-lined mounting positions, and remains rated IP66/IP67 for both configurations. In addition to the F152 evaluation unit, CMS, and ETAMATIC systems already referenced, the FFS08 is also compatible with LAMTEC’s MCC BC400 burner control, broadening the range of combustion management architectures into which it can be specified without changing the sensor itself.

Industrial Applications
The FFS08 is specified for flame safety monitoring on heating plant boilers, process combustion systems, hydrogen-fired plants, and natural gas and light fuel oil burners across power generation, refining, petrochemical, and district heating facilities. Its continuous-operation design and SIL 3 safety integration make it a critical safety component wherever unsupervised loss of flame could result in unburned fuel accumulation and explosion risk.
