The UV sensor has been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire.
Flame is detected typically within 3 sec. for a 1ft.2. (0.1m2) pan gasoline fire. A unique Fast UV Flame Detector Model (20/20FU) detects within several milliseconds a saturated UV signal caused by an explosion or a large fire.
The microprocessor design allows for unique field programmability making these flame detectors easily adaptable to all environments, applications and requirements.
The SharpEye UV Flame Detector incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.
Both U and UB models are self-contained, optical flame detectors that function as stand-alone units directly connected to external devices such as alarm systems or automatic fire extinguishing systems.
The UV detectors are particularly useful for detection of invisible flames from fuels such as: Hydrogen, Hydrides, Ammonia, Silane and other inorganic fuels.
* It is important to note that this detector must not be exposed to UV radiation sources such as: electrical arcs, sparks and welding, etc.

SharpEye 20/20L-LB UV/IR Flame Detector
The SharpEye UV/IR Optical Flame Detectors 20/20L and 20/20LB (which includes a BIT function) are an improved version of the well-proven Spectrex Ultra Violet/Infra Red (UV/IR) optical flame detectors featuring modern microprocessors and detection algorithms that provide excellent detection sensitivity combined with enhanced immunity to false alarms.
These enhanced models were developed in light of our highly successful experience in high-speed flame detection technology for both military and commercial industrial applications.
Both models are designed to detect hydrocarbon based fuel fires, hydroxy and hydrogen fires as well as metal and inorganic fires.
The UV/IR flame detector senses energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum.
The sensor band pass has been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire, and the lowest degree of matching to non-fire stimuli.
The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.
The IR sensor is sensitive to radiation over the range of 2.5 to 3.0 microns. The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous matching of radiant energy in both the UV and IR sensors triggers an alarm signal.
Features:
- UV/IR Dual-Sensor
- High-Speed Response
- 20 msec Response to Saturated Signal
- User Programmable Configuration
- Immune to False Alarms (solar blind)
- Automatic and Manual Built-In-Test (BIT) - LB
