Flame Scanner
System
overview
Design based on the ease of adjustment and use
Fully integrated, but small-dimension
No need of a controller or amplifier unit
Operates continuously with a minimum of attention
Advanced detection of IR and
UV radiations
Versatile flame scanner with two detectors, suitable for
oil, gas, coal and non-standard fuels
Detection of High flicker frequencies of
IR up to 5,000Hz
High-level technology with internal computer and data
recording on flash memories
Real-time innovative frequency decomposition of
IR flame
signal with programmable filters
Completely programmable IR software filters, over the entire
range for better flame discrimination. So, no predetermined
filtering values. If you need, with the mouse, place the
low-pass filter and/or the High-pass filter where you want

The
waveform of the IR signal as seen by the sensor is available

others, achieve the perfect alignment
Except for the FFRTs, there are no numerical data such as
values of gains, setpoints, thresholds, filters, etc.
modifiable by the operator. These are internal and automatic
processes that work according to the changes in the graphical
display with the computer mouse
8 minutes of graphical display of the flame responses,
allows to do the adjustments with the
PC mouse by
considering the history. The IR response reacts directly
with the addition of filters and their modifications
Any data, including those corresponding to the flame, can be
continuously recorded, for future reference
No complex programming sequence for the adjustments
No need for technician training
Analysis of the risk of flame failure for a given adjustment
A frequency spectrum based algorithm automatically rejects
artificial signals
Proven continuous self-checking system with shutter and
software integrity verification
Two independent fail-safe flame relay outputs, each having
his own adjustable FFRT (flame failure response time) and adjustable flame response (for
UV and
IR). The
No-Fault relay is also fail-safe
Records the number of different faults for to be view and
cancel later by operator
Measures the scanner temperature and records the maximum,
can be view and reset later by operator
Warns if the scanner temperature exceeds 85°C
Detects and warns if the flame is marginal
Supply 24 Volt
