Fireye 95UVS2-1 Ruggedized UV Flame Scanner Harsh Environments

Product Overview

Fireye 95UVS2-1 Ruggedized UV Flame Scanner Harsh Environments

The Fireye 95UVS2-1 is a high-reliability ultraviolet flame scanner engineered for continuous, mission-critical combustion monitoring in the most demanding industrial environments. As part of the proven Fireye 95 Series integrated detector platform, the 95UVS2-1 delivers consistent flame signal detection under conditions of extreme heat, vibration, electromagnetic interference, and airborne particulates — conditions that routinely challenge conventional sensing equipment. Whether deployed in a gas-fired boiler room, a petrochemical furnace, or a heavy industrial kiln, this unit maintains stable UV detection performance where operational continuity is non-negotiable.

Designed to interface directly with Fireye burner management systems — including the Fireye E110 Flame Safeguard Control and the Fireye NX550 Nexus Burner Management System — the 95UVS2-1 provides a clean, reliable flame presence signal that feeds directly into the safety interlock chain. Its compact, ruggedized housing is rated for elevated ambient temperatures and resists the ingress of dust and moisture that is endemic to cement plants, steel mills, and power generation facilities. The integrated UV sensing element responds rapidly to flame ignition and extinction events, enabling the burner management controller to execute safe shutdown sequences within the required safety response time.

In control cabinet environments where the 95UVS2-1 signal is processed alongside Fireye EP160 or EP260 amplifier modules, the detector’s low-noise output ensures that flame status is accurately interpreted even in the presence of strong electromagnetic fields generated by variable frequency drives, high-current motor starters, and industrial power distribution equipment. This EMI resilience is critical in facilities where PLC racks — such as Siemens S7-300 or Allen-Bradley ControlLogix systems — share enclosure space with high-power switching equipment.

The 95UVS2-1 is a direct replacement and upgrade path for legacy Fireye UV scanner models, making it a preferred spare parts choice for maintenance engineers managing aging combustion control infrastructure. Its backward compatibility with existing Fireye 95 Series scanner bases and wiring harnesses eliminates the need for costly rewiring or control system reconfiguration during planned maintenance shutdowns. Procurement teams can source this unit with confidence, knowing that it ships fully tested and ready for immediate installation.

Comprehensive Protection Solutions

The 95UVS2-1 does not operate in isolation — it is one component in a layered combustion safety and process control architecture. In a typical heavy industrial installation, the scanner works in concert with the Fireye EP260 Flame Amplifier, which conditions and amplifies the UV signal before passing flame status to the burner management controller. The Fireye NX550 Nexus BMS then executes the full burner sequencing logic — pre-purge, ignition trial, run, and lockout — based on the scanner’s continuous feedback.

At the PLC level, flame status and burner interlock signals are typically wired into safety-rated digital input modules on platforms such as the Siemens ET 200SP distributed I/O system or the Allen-Bradley 1734 POINT I/O series. These I/O modules relay the signal to the main safety PLC — often a Siemens S7-1500F or Rockwell GuardLogix controller — where it is processed within the safety program to enforce burner interlock logic and emergency shutdown (ESD) sequences.

Power to the scanner and its associated control circuits is typically supplied through 24VDC industrial power supplies such as the Phoenix Contact QUINT series or Siemens SITOP PSU100S, which provide regulated, filtered DC power that is immune to the voltage transients common in heavy industrial facilities. Upstream, Schneider Electric Acti9 or iC60 circuit breakers provide overcurrent protection for the control panel circuits feeding the scanner and BMS equipment.

In facilities where the combustion system communicates with a DCS — such as a Honeywell Experion PKS or Emerson DeltaV — the burner management system’s Modbus RTU or hardwired I/O interface bridges the flame scanner status into the plant-wide process historian and alarm management system, ensuring that combustion events are logged, trended, and available for safety audit review.

Application in Critical Infrastructure

The Fireye 95UVS2-1 is deployed across a broad spectrum of critical industrial infrastructure where flame failure detection is a regulatory and operational imperative.

In oil and gas processing facilities, the scanner monitors pilot and main burner flames on process heaters and reboilers, where an undetected flame failure could result in fuel accumulation and catastrophic ignition. Offshore platforms and onshore gas plants rely on UV flame scanners of this class to meet IEC 61511 functional safety requirements for burner management SIL 2 loops.

In power generation — including coal-fired, gas-fired, and waste-to-energy plants — the 95UVS2-1 monitors individual burner flames on multi-burner boiler fronts, providing the boiler management system with the per-burner flame status needed to safely manage load changes, burner sequencing, and emergency trips. The scanner’s fast UV response time is essential for meeting NFPA 85 Boiler and Combustion Systems Hazards Code requirements.

In metallurgical and mining operations — including blast furnace hot blast stoves, ladle preheaters, and ore roasting kilns — the 95UVS2-1 operates in environments characterized by high radiant heat loads, heavy dust, and mechanical vibration. Its ruggedized construction and UV-specific detection (which ignores visible light and infrared radiation from hot refractory surfaces) make it uniquely suited to these high-interference environments.

In water treatment and municipal infrastructure, the scanner monitors biogas and natural gas burners on sludge dryers and thermal oxidizers, where reliable flame detection is essential for both process efficiency and environmental compliance.

Security & Quality FAQ

Q1: What does the 12-month warranty cover, and how is a warranty claim processed?
The 12-month warranty covers all manufacturing defects and functional failures under normal operating conditions from the date of shipment. If the unit fails to perform to its published specifications within the warranty period, TOPNLMS will arrange for replacement or repair at no additional cost. Claims are initiated by contacting [email protected] with the order reference and a description of the fault.

Q2: How is each unit tested before shipment?
Every Fireye 95UVS2-1 unit in our inventory undergoes functional verification prior to dispatch. Testing confirms UV sensing element response, signal output integrity, and connector condition. Units that do not pass functional verification are quarantined and not offered for sale. A test record is available upon request for quality-critical procurement processes.

Q3: Is the 95UVS2-1 compatible with my existing Fireye burner management system and scanner base?
Yes. The 95UVS2-1 is designed as a plug-in replacement for the Fireye 95 Series scanner base and is electrically compatible with Fireye amplifier modules including the EP160, EP260, and the NX550 Nexus BMS platform. No wiring modifications are required for like-for-like replacement. If you are integrating into a non-Fireye BMS, please contact our technical team to confirm signal compatibility before ordering.

Q4: Can TOPNLMS support long-term or repeat supply of this model?
Yes. TOPNLMS maintains ongoing stock of Fireye 95 Series components, including the 95UVS2-1, to support planned maintenance programs, annual turnaround schedules, and emergency spare parts requirements. We can provide volume pricing, scheduled delivery agreements, and advance reservation of stock for customers with predictable annual consumption.
