High temperature furnace flame monitoring system

High Temperature Furnace Flame Monitoring System

A robust industrial monitoring solution engineered for extreme furnace environments up to 1800°C. The LM-NK800G features a durable stainless steel probe hood equipped with a sapphire heat-resisting lens and a special spiral air curtain to prevent dust accumulation. It delivers high-definition 1920×1080 resolution imaging with 27× optical zoom for detailed flame analysis. A critical safety feature is the automatic probe retraction system, which instantly withdraws the device from the furnace during power loss or cooling failure, protecting sensitive components from extreme heat. Ideal for nuclear energy facilities, blast furnaces, and industrial heating applications.

High Temperature Furnace Flame Monitoring System LM-NK800G

Product Feature

The LM-NK800G High Temperature Furnace Flame Monitoring System is a robust industrial monitoring solution engineered for extreme environments. It features a durable stainless steel probe hood and a sapphire heat-resisting lens capable of withstanding furnace temperatures up to 1800°C.

To ensure clear visibility, the system utilizes a special spiral air curtain that prevents dust accumulation on the lens. It is equipped with a high-definition camera (1920×1080 resolution) featuring 27× optical zoom for detailed flame analysis. A critical safety feature is the automatic probe retraction, which withdraws the device from the furnace in the event of power loss or cooling failure. Ideal for nuclear energy industry applications and other high-temperature furnace monitoring.

FAQs

Q1: How does the High Temperature Furnace Flame Monitoring System protect the equipment in case of failure?

A: The system is designed with an intelligent automatic protection mechanism. If there is a sudden power outage, or if the compressed air or cooling water supply fails, the probe hood will automatically exit the furnace. This ensures that the sensitive camera and lens are not damaged by the extreme heat of 1800°C.

Q2: Can the High Temperature Furnace Flame Monitoring System maintain a clear image in dusty furnace environments?

A: Yes. The system features a special spiral air curtain design that creates a barrier to prevent dust from gathering on the lens. Additionally, it uses a sapphire heat-resisting lens which is highly durable. Combined with a 27× optical zoom (and electronic zoom 3.6-78), it provides clear, high-definition (1920×1080) monitoring even in harsh conditions.

Q3: What are the installation requirements and operating temperature limits for the High Temperature Furnace Flame Monitoring System?

A: This system applies to all kinds of high-temperature furnaces, specifically designed for furnace walls with a thickness of around 500 mm. It can withstand furnace temperatures up to 1800°C. The control device operates in ambient temperatures from -5°C to 75°C, while the automatic exit device functions between -20°C and 100°C.
