The optimized detection angle delivers comprehensive coverage, fully satisfying full-area flame monitoring requirements for large-space furnaces such as large boilers, turbine combustion chambers and industrial incinerators.
A single unit can precisely monitor the flame status of one burner, reducing equipment quantity and simplifying on-site layout.
2.6 Built-In Intelligent Self-Diagnosis for Convenient and Efficient Maintenance
It supports power-on self-test and real-time operational self-diagnosis, automatically monitoring potential risks including contaminated optical probe, circuit fault, abnormal power supply and faulty signal loops.
Device faults can be indicated via output signal status, enabling maintenance personnel to rapidly locate fault points without frequent disassembly and inspection, greatly lowering daily maintenance workload and repair costs.
2.7 Standardized Mechanical Interface for Easy Installation and Replacement
The device adopts a standard 3/4-inch NPT stainless steel threaded interface with stable installation and strong vibration resistance, compatible with standard furnace mounting bases.
Thanks to standardized dimensions and interface definitions, faulty legacy units can be directly replaced in situ without modifying mounting bases or wiring. The unit can be commissioned and put into service after power-up, achieving high maintenance efficiency and low renovation cost.

Relying on built-in high-precision UV optical sensing components, the device selectively captures unique ultraviolet spectrum signals generated by furnace combustion flames, effectively shielding infrared radiation, ambient light and equipment reflection interference.
Raw optical signals are filtered, shaped, amplified and precisely conditioned before being transmitted to the core computing chip.
