Selection Suggestions and Precautions
Selection Suggestions
Choose HONEYWELL EG1033AA / HONEYWELL EG1033AA01 for GE gas turbines or Honeywell FlameCurtain systems needing solar-blind UV detection and fast safety response.
Prioritize it for applications where sunlight/hot-surface false triggers risk production loss or safety incidents.
Precautions
Use Honeywell FlameView software to set response thresholds and test outputs for HONEYWELL EG1033AA / HONEYWELL EG1033AA01.
Ensure 20-35V DC power stability; voltage dips can cause false no-flame alarms in HONEYWELL EG1033AA / HONEYWELL EG1033AA01.
Match phototube type to HONEYWELL EG1033AA / HONEYWELL EG1033AA01 (Geiger Mueller) for reliable UV detection.
Avoid exceeding 330m (1000ft) sensor-to-amplifier cable length; this can degrade signal integrity.
Calibrate annually and replace phototubes every 10,000 hours to maintain HONEYWELL EG1033AA / HONEYWELL EG1033AA01 accuracy.
