Fireye 85UVF1-1QD is a specialized ultraviolet (UV) flame detection probe for industrial combustion systems, belonging to the flame detection product line of Fireye (a brand under Honeywell) in the United States. It confirms the combustion status by detecting ultraviolet radiation in the flame, ensuring the safe operation of the burner.
1. Core Features
UV detection technology
Sensitive to ultraviolet radiation in flames (usually within the wavelength range of 180-260 nm), with strong anti-interference ability, avoiding misjudgment (such as furnace background light or infrared radiation).
High sensitivity and response speed
Quickly detect flame status (millisecond level response) to ensure safe ignition and operation of the burner.
Widely applicable fuels
Support flame detection of clean fuels such as natural gas, liquefied gas, and light oil.
Durable design
Resistant to high temperatures and corrosion, suitable for harsh industrial environments such as boilers, heating furnaces, incinerators, etc.
Modular compatibility
Can be seamlessly integrated with Fireye series combustion controllers (such as NXM series).
2. Technical parameters
Detection type: Ultraviolet (UV)
Applicable fuels: natural gas, liquefied petroleum gas (LPG), light oil
Detection distance: typical range of 30-60 cm (depending on flame intensity and installation angle)
Viewing angle range: approximately 80 ° conical viewing angle
Working voltage: 24 V AC/DC ± 10%
Output signal:
Passive contact (dry contact): Close in the presence of flames and disconnect in the absence of flames.
Load capacity: typically 2 A @ 120 V AC/1 A @ 240 V AC.
Environmental temperature:
Probe body: -40 ° C to+85 ° C (avoid direct contact with high-temperature flames).
Electronic components: -40 ° C to+70 ° C.
Protection level: IP65 (dustproof, anti low pressure spray).
3. Typical application scenarios
Industrial boilers: Monitor gas or fuel flames to prevent accidental flameout.
Hot air stove/heating furnace: Ensure successful ignition and continuous stable operation of the burner.
Incineration system: flame monitoring during the incineration process of garbage or waste.
Petrochemical equipment: safety protection for heating furnaces and cracking furnaces.
4. Key points for installation and debugging
Installation location:
Aim at the area of the flame with the strongest ultraviolet radiation (usually at the root of the flame) and avoid being obstructed by smoke or water mist.
Avoid probe mirror contamination (regular cleaning is required).
Wiring requirements:
Use shielded cables to reduce electromagnetic interference, and grounding must comply with industry standards.
Functional testing:
After ignition, confirm that the probe output signal is normal and trigger the safety interlock shutdown in a timely manner when there is no flame.
5. Maintenance and troubleshooting
Regular cleaning:
Wipe the quartz lens of the probe with a soft cloth to prevent dust or oil stains from affecting sensitivity.
Common faults:
False alarm: Check for lens contamination, flame stability, or probe angle deviation.
Continuous output of fire signal: It may be due to ultraviolet interference or probe circuit failure, and power off detection is required.
Suggested lifespan:
The typical lifespan is 5-10 years, depending on the usage environment. It is recommended to perform calibration checks every 2 years.
6. Compatibility and Accessories
Controller compatibility: Fireye NXM, UV10, UV20 series, etc.
Optional accessories:
Install brackets (such as Fireye QD series dedicated brackets).
Extend the cable (high-temperature shielded wire).
Protective casing (for high temperature or corrosive environments).
