In-Furnace Monitoring Camera System
Mounted on the furnace wall to observe material, equipment, molten material and flames. The camera and pinhole lens are installed in a specially designed high-temperature protective housing. The assembly automatically retracts from the furnace if compressed air or power is lost, or an overtemperature condition occurs. Applications include metallurgy, steel, power generation, glass, building materials and machinery.
For oil-, coal- and gas-fired furnaces, compressed-air cooling allows the lens to extend directly into the furnace below 2000°C for continuous observation of material heating, annealing, waste combustion and slag combustion flame patterns.
Engineered airflow creates a swirling protective air curtain in front of the lens to reduce dust contact and support stable, continuous operation with minimal maintenance.
- Monitor flames and material inside heating furnaces. The source lists conflicting temperature limits (below 2000°C / over 2000°C); confirm the rated operating limit and cooling requirements before selection.
- Automatic insertion and retraction using sensors and PLC control, with manual operation available
- Pressurized air forms a protective curtain at the lens tip to reduce dust accumulation
- Camera temperature sensor with on-screen readout and audible alarm output
