Description
1. At-A-Glance Executive Brief
- Model: C7012F1052
- Brand: Honeywell
- Part Type: Solid-State Ultraviolet (UV) “Purple Peeper” Flame Detector
- Lifecycle Status: Active / Hazardous Location Rated
- Weight: ~2.1 kg
2. Technical Introduction
A faulty ultraviolet flame detector trips burner safety interlocks on large industrial furnaces, halting production lines while maintenance crews wait for hard-to-source safety-rated components.
This explosion-proof optical sensor mounts directly onto burner observation housings via a standard threaded connection to monitor ultraviolet radiation emitted by gas and oil flames. Designed for continuous duty, it converts optical flicker patterns into reliable electronic signals for burner management systems, preventing unburned fuel accumulation.
- Best Suited For: Industrial process heaters, utility boilers, and hazardous-area gas burner assemblies.

4. Field Engineer’s Tech Notes
- Quartz Viewing Window Maintenance: Petroleum residue or soot buildup on the internal quartz window will severely attenuate UV signal transmission. Clean the glass periodically with a lint-free optical solvent; a degraded signal path causes nuisance flame-out trips under heavy firing conditions.
- Electrical Conduit Sealing: Because this unit operates in explosion-proof environments, ensure all threaded conduit entries use approved seal-off fittings packed with sealing compound to prevent vapor migration into control cabinets.
5. Adaptive QA & Testing Protocol
Each unit undergoes functional bench validation before leaving our warehouse. Testing involves exposing the UV phototube to a calibrated ultraviolet radiation source across regulated modulation frequencies to verify proper shutter operation and signal amplification. Insulation resistance and leakage current checks are performed on all internal circuitry. Comprehensive test reports are available upon request to satisfy plant insurance and safety compliance audits.
6. Buyer’s FAQ
- What is the standard warranty length for this flame detector?All units are backed by a comprehensive 12-month operational warranty from the date of invoice.
- Is expedited shipping available for unexpected plant outages?Yes. In-stock inventory ships same-day via priority air carriers to ensure your facility minimizes costly downtime.
- Is this a direct drop-in replacement for older C7012 series models?Yes. This unit retains exact dimensional and electrical connection profiles for legacy Honeywell burner management setups, though verifying amplifier compatibility is recommended.
