1. The probe cap can be inserted into the neck for about 1 meter
2. Observe the movement direction of the workpiece through the wide-angle to high-temperature zoom pinhole lens, more intuitively and comprehensively reflect the specific situation of the neck water wrapped in the furnace
3. The probe cover is made of stainless steel with good temperature/corrosion resistance
4. Special dust proof design, the lens is not easy to accumulate dust
5. Special water cooling design for normal use under poor water quality conditions
6. The self-developed and produced high-temperature pinhole zoom lens has a horizontal resolution of more than 2 million pixels and can withstand temperature of 350 degrees without cooling.
7. Manual zoom high temperature pinhole lens can be selected to meet the observation requirements of different kilns and different production processes.

The Deep Card Neck Water Bag enhances glass production by increasing clarification temperature, extending clarification time, and improving clarification effectiveness. This helps reduce defects like bubbles and improves overall glass quality.
Unlike traditional round steel tube water bags (e.g., 76mm diameter, 160mm depth), the updated deep design addresses evolving glass technology and energy efficiency demands. The deep card neck is inserted deeper into the molten glass and is constructed with a rectangular seamless steel tube welded across its center.
A dedicated Card Neck Water Bag Water Level Monitoring System ensures safe operation: the stainless steel structure operates under prolonged high temperatures while water circulation and HD monitoring jointly detect potential leaks, enabling long-term reliable performance in high-temperature glass liquids.

Q1: What is the primary function of this system in glass production?
A: This system is specifically designed to monitor the water level inside the deep card neck water bag of glass melting furnaces. By providing real-time HD visual feedback, it enables early detection of potential water leaks, ensuring safe and uninterrupted furnace operation. Additionally, the deep card neck design helps increase clarification temperature and time, which significantly reduces defects like bubbles and improves overall glass quality and energy efficiency.
Q2: Can this monitoring system withstand the extreme heat inside a glass furnace?
A: Yes, it is engineered for harsh industrial environments. The probe cover is made of corrosion-resistant stainless steel and can be inserted approximately 1 meter into the furnace neck. The self-developed high-temperature pinhole zoom lens is capable of withstanding temperatures up to 350°C without active cooling, while the complete system is rated for continuous operation in furnaces reaching up to 1800°C. It also features a specialized dust-proof design to keep the lens clear in dirty conditions.
Q3: What optical clarity and cooling features does this system offer?
A: The system delivers high-definition imaging with a horizontal resolution of over 2 megapixels and a continuously adjustable focal length (F4-F20), allowing operators to clearly observe workpiece movement and water bag status. For thermal management, it utilizes a robust water cooling design that functions reliably even under poor water quality conditions, minimizing scaling and maintenance. Paired with a compressed air cleaning system, it ensures long-term, stable performance with minimal downtime.
