- Fully microprocessor-based integrated flame scanners with electronic self-checking
- Two versions with solid-state detectors: 85UVF (295-340 nm) and 85IRF (830-1100 nm)
- For continuous operation on oil and gas power & industrial burners, in power, refinery and petrochem lowNOx applications, including Duct Burners, incinerators
-
High discrimination capabilities in difficult multi-burner and multi-fuel environment
-
Internal flame relay with automatically set ON/OFF thresholds
-
FFRT 1 - 4 sec.
-
The scanner setup procedure during Learning Mode:
- the amplitudes of the target flame are automatically measured and stored
- optimum flame relay ON/OFF criteria are set and stored
- the appropriate sensor gain is automatically selected -
Automatic aiming – function AIM
-
Advanced diagnostics: the Advanced Trip Diagnostic function allows detecting the cause of the scanner's termination, Trip Threshold Adjustment allows you to set thresholds for flame quality criteria: Average Amplitude, Power Spectrum Density, Best Fit, Peak-to-Median Ratio.
- User Interface Module is password protected: pushbutton keypad and informative LEDs. These provide a continuous indication of flame signal, flame relay status, scanner status as well as the selected mode of operation. The keypad is used for setup and changing operating parameters
-
In case of possible scanner overheating, long distance to flame or tilting burner the fiber optic assembly is available
-
