- Fully microprocessor-based integrated flame scanners
- Solid-state detectors: type 95UV UV (295 – 320 nm), type 95IR IR (700 – 1 700 nm), type 95DS utilizes both sensors
- Continuous operation, elctronic self-checking Fail-Safe
- High and very high discrimination capabilities - good for difficullt multi-burner applications
-
The S1 Model - offers manual selection and adjustment of three modulation frequencies, sensor gain, flame relay ON/OFF thresholds
-
The expanded S2 Model - allows automatic programming (AutoTune) with manual override capability, 21 choices of flame flicker frequency, four selectable programmable files to store setpoints, remote communication capability via RS MODBUS output
-
Model S2 AutoTune - scanner scans the flame flicker frequency spectrum in flame ON, and flame OFF (background radiation present) conditions and then selects the appropriate sensor gain, bandpass frequency, sensor range for optimum flame ON/OFF discrimination and selects also the optimum Flame Relay ON and OFF thresholds
- In case of possible scanner overheating, long distance to flame or tilting burner the fiber optic assembly is available
- Flame Failure Response Time (FFRT): selectable 1 to 6 seconds
-
8 character LED display and 4 push-button password-protected keypad to enable the user to view operating parameters and select setpoints
- Supply 24 VDC
- Outputs: flame relay NO, fault relay NC, analogue 4 – 20 mA
- Quick-disconnect: 12-pin of a screw type (basic scanner models)
- Temperature rating -40 to +65°C
- in Model S2 available optional software for start-up or flame analysis
- Housing is available in explosion-proof version ATEX Ex d IIC T6
- Approvals: DIN-DVGW, CE
- Designed to meet Safety Integrity Level SIL-3 according to EXIDA Report
- Low installation cost
