Main Functions

Honeywell C7012A, C7012E1104, C7012E1112 Ultraviolet Flame Detector

Detects ultraviolet UV radiation emitted by combustion of natural gas, LPG, fuel oil and pulverized coal. Converts flame UV light intensity into electrical flame‑present signal and transmits it to burner flame‑safeguard amplifier/controller.
C7012A: Basic flame monitoring function. Outputs flame‑on / flame‑off status signal; no built‑in self‑test shutter. Relies on external test means to verify sensor health status霍尼韦尔中….
C7012E1104 / C7012E1112: Self‑checking design with built‑in oscillating mechanical shutter. Periodically blocks UV incoming path to automatically verify sensor function. Identifies sensor failure, window fouling or tube burnout, sends fault signal to burner control unit to avoid false flame indication

Honeywell C7012A, C7012E1104, C7012E1112 Ultraviolet Flame Detector

Quartz viewing window isolates high‑temperature combustion chamber environment, while permitting UV light transmission. Cast‑aluminum housing meets NEMA‑4 dust‑proof and rain‑proof requirementsHoneywell.
Supports parallel wiring of two detectors to reduce nuisance shutdown risk under difficult flame‑sight conditions.

Honeywell C7012A, C7012E1104, C7012E1112 Ultraviolet Flame Detector

Cooperates with flame safeguard controls: when flame is lost during burner operation, it sends loss‑of‑flame signal to trigger safety interlock, cuts fuel supply to prevent hazardous unburned‑fuel accumulation.

Honeywell C7012A, C7012E1104, C7012E1112 Ultraviolet Flame Detector

Applied for flame supervision of industrial combustion equipment: gas‑fired / oil‑fired industrial furnaces, boilers, heaters, thermal oxidizers, dryers and process burners in petrochemical, power plant and heating industries.More products: www.plcva.com

Honeywell C7012A, C7012E1104, C7012E1112 Ultraviolet Flame Detector

Installed on sight pipe penetrating combustion chamber wall; optical path faces burner flame. Matches Honeywell flame safeguard amplifiers to constitute complete burner safety monitoring loop.
C7012A applies to general‑purpose burner systems without mandatory sensor self‑check requirement. C7012E1104 (240VAC) and C7012E1112 (120VAC) are used for safety‑critical combustion systems requiring automatic self‑diagnosis of flame detector hardware faults
OEM spare replacement components. When original UV detector ages, UV tube degrades or housing is damaged, these units restore flame‑detection and burner safety‑interlock function, preventing furnace safety hazards caused by flame‑monitor failure.
