Q1: How deep can this High Temperature Industrial Television be inserted into the tin tank?
A: This High Temperature Industrial Television is designed with a probe cover that can be inserted several meters directly into the tin tank. This deep insertion capability allows for comprehensive monitoring of the specific conditions and workpiece movement deep inside the furnace, providing a much more intuitive view than external cameras.
Q2: What is the image quality and zoom capability of this High Temperature Industrial Television?
A: The system delivers exceptional clarity with a horizontal resolution of more than 2 million pixels. It features a 90-degree turning high-temperature zoom pinhole lens with a variable focal length (continuously adjustable f4-f20). This allows operators to control the size range and sharpness of the image from a distance, ensuring detailed observation of the production process.
Q3: How does this High Temperature Industrial Television handle extreme heat and cooling requirements?
A: The system is engineered for harsh thermal environments. The self-developed lens can withstand temperatures of up to 350°C without any active cooling. For higher temperatures, it utilizes a special water coolingdesign that is robust enough to function normally even under poor water quality conditions. It is suitable for furnace temperatures up to 1500°C.
