Description
Honeywell C7012F1052 (Purple Peeper) Self‑Checking UV Flame Detector
Product Overview
C7012F1052 is Honeywell explosion‑proof self‑checking solid‑state ultraviolet flame detector, well‑known as Purple Peeper® series It detects ultraviolet UV radiation generated by fuel combustion. Designed for hazardous classified locations, it works together with Honeywell dynamic self‑check flame safeguard amplifiers (R7247C, R7747C, R7847C) to implement continuous flame supervision for industrial burners. This unit is widely applied for new burner projects, field maintenance and spare‑part replacement of existing combustion safety systemsfile.yizim….

Core Features
- Built‑in self‑diagnostic checking function: Periodically performs internal self‑test to verify detector health, avoids undetected sensor failure which could cause loss‑of‑flame protection failure.
- Explosion‑proof heavy‑duty enclosure: Designed for Class I Division 1 hazardous locations, suitable for explosive gas‑vapor workshop environments.
- Wide UV detection field‑of‑view: 110‑degree viewing angle, flexible aiming adjustment for different burner installation layouts. Supports mounting at any angle: horizontal, vertical or tilted position.
- High‑pressure‑rated quartz viewing window: 100 psi pressure resistance, adapts to furnace positive‑pressure operating conditions.
- Parallel redundant installation support: Two detectors can be wired in parallel to reduce nuisance safety shutdown risk for critical combustion loops霍尼韦尔中….
- Color‑coded pre‑wired cable: Simplifies field wiring and commissioning work.
- Robust industrial construction: Resists vibration, temperature cycling and dust contamination in heavy‑duty combustion site environment.
Main Functions
- Capture ultraviolet radiation emitted by gas / oil / coal combustion flame, convert flame optical signal into electrical signal and transmit to matched flame safeguard amplifier.
- Execute automatic periodic self‑check to validate internal detector circuit and sensor integrity; report fault condition to burner safety control system upon self‑check failure.
- Continuously monitor flame presence during burner running; send loss‑of‑flame signal to safeguard amplifier once flame extinguishes, trigger burner safety shutdown sequence.
- Support multi‑detector parallel configuration for enhanced safety reliability for high‑risk furnace and boiler applications.
- Cooperate with Honeywell flame safety amplifiers to complete full‑sequence burner flame supervision during ignition, stable burning and flame‑out conditions.
