Key Features

  1. Simplicity series integrated UV flame scanner with ATEX Ex‑d IIC T6 flame‑proof housing, suitable for Zone 1 explosive hazardous‑area installation.
  2. Electromechanical shutter self‑check mechanism continuously validates UV sensor health, avoids false flame signal risk.
  3. Built‑in flame relay with fast 1‑second flame‑failure response for safety‑critical burner trip interlock.
  4. 4‑20 mA analog output delivers real‑time flame intensity for DCS trending and diagnostics.
  5. CEX housing uses internal terminal‑block wiring, must match ATEX‑approved cable glands for field installation.
  6. Requires continuous clean dry purge‑air to prevent lens contamination from furnace flue‑gas and dustFireye.
  7. Minimal configuration, out‑of‑box operation without complex programming.
  8. Manufactured in USA; EOL obsolete, only NOS or fully‑tested refurbished spare‑parts available.

 

Main Functions

  1. Detect ultraviolet radiation from natural‑gas / light‑oil flames, determine flame‑present or flame‑out status.
  2. Internal relay contact output for burner safety interlock; trigger fuel shut‑off within 1‑second upon flame loss.
  3. Convert flame‑signal strength into 4‑20 mA analog signal and transmit to upper‑level DCS/SCADA monitoring system.
  4. Mechanical shutter implements automatic sensor self‑test, reports sensor fault or lens fouling alarms.
  5. Ex‑d explosion‑proof enclosure permits direct installation inside Zone 1 hazardous process area.
  6. Purge‑air interface protects optical window against high‑temperature flue‑gas and soot deposition.
  7. Cooperate with Fireye burner safety controller to realize complete burner flame‑safeguard protection logic.
  8. Serve as UV flame‑detection sensing unit for industrial combustion safety system.
