Product Overview
The Honeywell C7012E1104 is a high-sensitivity, solid-state ultraviolet (UV) flame detector engineered for the continuous monitoring of industrial burner flames. It specifically identifies the UV radiation spectrum emitted during the combustion of carbon-based fuels, such as natural gas, oil, and coal. Designed for high-stakes environments, the C7012E1104 integrates dynamic self-checking circuitry to verify its own operational integrity 60 times per minute. This detector provides a critical safety layer for large-scale boiler and furnace operations, ensuring immediate fuel shut-off upon flame failure.

Engineering Advantages
-
Dynamic Self-Checking Integrity: The detector employs a mechanical shutter that periodically blocks the UV sensor's view. This allows the electronics to verify the "no-flame" state and confirm that the sensor has not failed in an "always-on" (shorted) condition—a common failure mode in standard UV tubes.
-
Explosion-Proof Reliability: The heavy-duty housing meets strict requirements for hazardous locations. This robust design eliminates the need for external protective shields in explosive atmospheres, simplifying installation in refineries and chemical processing plants.
-
High-Temperature Resilience: Unlike standard commercial sensors, the C7012E1104 operates effectively up to +125°C. This thermal durability allows for mounting closer to the burner sight pipe without requiring expensive external cooling accessories in most applications.
-
Superior Signal Discrimination: The solid-state UV sensor ignores IR radiation and "hot brick" glow from the furnace interior. It focuses exclusively on the high-energy UV signature of the actual flame, preventing false "flame-on" signals caused by background thermal noise.
FAQs
Q: Is the Honeywell C7012E1104 unit 100% Brand New?
A: Yes. We supply only 100% Brand New and original Honeywell factory hardware. Each detector ships in original packaging with its factory-verified serial number and a 12-month industrial warranty.
Q: Does this detector require a specific amplifier?
A: Yes. For proper operation, you must pair the C7012E1104 with a compatible Honeywell Flame Signal Amplifier (such as the R7847C) and a Burner Management System (BMS) like the 7800 SERIES.
Q: Can I use this detector for coal-fired burners?
A: Absolutely. The UV sensor detects the ultraviolet emissions present in coal combustion. However, ensure the sight pipe remains clear of heavy soot or ash buildup, as physical obstructions can block the UV light from reaching the sensor.
Q: What is the benefit of the NEMA 4 rating?
A: The NEMA 4 rating ensures the detector is completely protected against windblown dust, rain, and hose-directed water. This makes the C7012E1104 suitable for both indoor boiler rooms and outdoor industrial installations.
