Integrated Flame Scanners 95UV/95IR/95DS Insight

  • Fully microprocessor based integrated flame scanners
  • Solid state detectors: UV (295 – 320 nm), IR (700 – 1 700 nm), or both
  • 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 scanns 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 opticassembly is available
  • Flame Failure Response Time (FFRT): selectable 1 to 6 seconds
  • 8 character LED display and 4 push-button password protected keypad enable the user to view operating parameters and select setpoints
  • Supply 24 VDC
  • Outputs: flame relay NO, fault relay NC, analog 4 – 20 mA
  • Temperature rating -40 to +65C
  • in Model S2 available optional software for start-up or flame analyzis
  • 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
