Features
Applicable for kinds of blast furnace tuyere
Real time online monitoring on Blast furnace tuyere
Probe housing made of stainless steel with good corrosion resistance
Compact size of Blast furnace tuyere camera probe, easy maintenance and replacementProbe is installed at the back of small mirror, can be inspected by human through Beamsplitter.
The tuyere probes are interchangeable, that is, one camera probe can be installed behind multiple tuyere mirrors to monitor the required tuyere, thereby reducing cost
Lens: high temperature pin hole, long focal length
Camera: Miniature color camera, high definition, 720 line horizontal resolution
Beamsplitter: a beamsplitter is installed in front of the camera lens protectivecover, onsite inspectors can also observe the situation in the tuyere through the beamsplitter.
Easy installation: the front of the lens camera protective cover has a circular flange, which is directly screwed and fixed on the tuyere observation hole with3 M8 screws, no additional fixing bracket is required
Nitrogen cooling: The front end of the device is closely attached to the observation hole, the temperature is high, so it needs nitrogen to cool
