Industrial process cameras for kilns, furnaces and metal smelting

Cameras that look inside a cement kiln, a furnace or a casting line, where the temperature would destroy an ordinary camera in seconds, so operators can see the flame, the material and the equipment.

Seeing inside the process

High-temperature camera systems use a narrow lens tube through the furnace wall, a protective housing cooled by air or water, and a purge of clean air that keeps dust off the lens. They show the burner flame, the burning zone, the clinker cooler, slag and the charge, so operators adjust the process from what they see. Thermal versions add temperature measurement across the image, for example along a rotary kiln shell or inside a furnace.

The protection system is half the product

A process camera survives only while its cooling works. A properly engineered system monitors cooling air or water and lens temperature and automatically retracts the camera from the furnace if cooling or power fails. We design the cooling supply, the retraction unit, the cable route and the maintenance access together with the plant, because these decide how long the camera lasts.

From the picture to the control room

The video and temperature data go to the plant control room and can be tied into the process system, so an operator sees the flame beside the process values. We integrate with the plant's SCADA or control system over open protocols, and cameras in classified areas follow the rules for hazardous areas.

What we do on this kind of project

We select the equipment to fit your site, not to clear a stock list. We design the system, install and commission it, and keep it working.

Before you buy

Questions to settle first

These decide cost and performance more than the brand on the box. We work through them with you at survey stage.

What must the operator see or measure, and at which point of the process?
What are the temperature and dust conditions at the viewing port?
Is clean, dry compressed air or cooling water available?
Is there an existing port, or must one be made during a shutdown?
Should the image go into the control system or stay on its own screen?
When is the next planned shutdown?

Frequently asked questions

How does a camera survive inside a kiln or furnace?

It sits in a cooled protective housing with a narrow lens tube, with an air purge that keeps the lens clean. If cooling fails, the system withdraws the camera automatically.

Can these cameras measure temperature?

Yes. Thermal process cameras measure temperature across the image, which helps monitor the flame, the material and the refractory. The measurement range and accuracy depend on the model and the conditions.

Can installation be done while the plant is running?

Some work can, but creating or changing a viewing port in a furnace wall is normally planned for a shutdown. We prepare everything in advance so the installation fits the shutdown window.
