The innovative
Multi-Spectral Infrared (MSIR) FL4000
Flame Detector
from General Monitors is now available with HART® communications.
The FL4000, with its next-generation MSIR sensor that
incorporates neural network technology (NNT), provides
highly reliable flame monitoring with superior false
alarm immunity, an exceptionally wide field of view
(FOV) and the industry’s longest extended range.
HART is a field-proven instrumentation communications
protocol that is easy-to-use and provides reliable
two-way digital communication without disturbing the
integrity of the 4-20mA analog signal. HART communications
permit remote process variable interrogation, cyclical
access to process data, parameter setting and diagnostics.
Unlike other technologies, HART provides a unique communication
solution that is backward compatible with the installed
base of instrumentation in use today.
Setting a new industry standard for performance, reliability
and value, the FL4000 Flame Detector gives process
and plant engineers a powerful new tool in protecting
people, equipment and facilities from dangerous hydrocarbon
flame sources. It provides exceptional performance
and reliability while minimizing operational costs
associated with false alarms.
Designed with an exceptionally reliable NNT flame discrimination
algorithm, the FL4000 detector is highly immune to
false alarms while at the same time offering extended
range (up to 230 feet) and wide field-of-view (FOV)
characteristics (100° at 50 feet). For example,
the FL4000 MSIR flame detector provides false alarm
immunity to arc welding as close as 5-15 feet. Other
features include built-in COPM (Continuous Optical
Path Monitoring), a self-testing feature designed to
check the optical path integrity of the detector elements
and the related electronic circuitry once every two
minutes. Serial ports allow up to 128 units (247 using
repeaters) to be linked up to a host computer using
either HART or MODBUS® communications.
The advanced FL4000 combines an optical MSIR sensor
array with NNT processing. NNT is based on artificial
neural networks (ANN), which are mathematical models
of neurons in the human brain that correlate given
signal patterns with target flame conditions. The optical
IR sensor array and the neural network function together
as an adaptive and intuitive decision-making mechanism.
The resulting flame detector provides the industry’s
most reliable discrimination between actual flames
and costly false alarm sources.
The MSIR sensor array in the FL4000 allows the detector to sample different IR
spectral areas to detect a flame. Each sensor’s analog signal is sampled
and then converted into digital format for initial signal pre-processing to extract
time and frequency information. The time and frequency information are used by
the FL4000’s proprietary neural network classification algorithm to identify
if input IR signals are emitted from a flame or non-flame source. The flame or
non-flame decision is then reported as an output via LEDs, relays and MODBUS.
Because of its accurate and reliable flame detection scheme, the FL4000 sets
a new standard for performance, reliability, safety and value. Furthermore, the
FL4000’s ability to differentiate spectral radiation emitted by actual
flames from that emitted by background ambient radiation is exceptional. This
differentiation is extremely crucial, as failure to do so results in either undetected
fires, or more commonly, nuisance false alarms Links of interest FL4000
