Explosion-Proof Peep Type Pinhole Furnace Camera

The Explosion-Proof Peep Type Pinhole Furnace Camera serves as a key visual component in machine vision-based flame observation systems for petrochemical heating furnaces. Certified for use in Group ⅡC explosive atmospheres (including hydrogen, acetylene, etc.), this furnace camera provides a safe, discreet view directly inside the furnace chamber. It captures smooth, real-time images of burner flames, furnace tubes, and nozzles, enabling operators to visually monitor combustion conditions and coking.

This visual feed is then analyzed by machine vision technology, which automatically detects critical events such as individual burner flame extinction or unexpected fire bursts. Upon detection, the system outputs alarm signals to the DCS or automatic control system for immediate intervention, ensuring safety and operational stability.

Explosion-Proof Peep Type Pinhole Camera

Explosion-Proof Peep Type Pinhole Furnace Camera Function Feature

● The furnace flame observation system adopts the industry standard service-oriented network architecture, and constructs the integrated management platform integrating video monitoring, image analysis, display and management

● The structure and C/S architecture can effectively reduce the complexity of system construction, improve the flexibility of distributed deployment, provide unified internal and external interface services, and facilitate system expansion and centralized management. The system supports ONVIF interface protocol and provides access ports for office network and CCTV throughout the factory.

● Flashover integrated high temperature camera is a monitoring device combined with digital HD industrial camera and machine vision technology. The high temperature resistant shield forced to be cooled by vortex wind can extend the camera into the furnace at 2000℃ for observation. Digital HD industrial camera automatically adjusts the output level according to the brightness change of flame to keep the image clear; Equipped with the axial cruise device, the camera can make ±180° axial patrol and realize the observation of the whole furnace.

● Image analysis server is a powerful analysis tool, which adopts machine vision technology to simulate the visual behavior of human eyes, can accurately identify the flame-out of burner and furnace tube leakage in the visual field, and output alarm signal, and constitute a complete monitoring system with flameproof high temperature integrated camera.
