HWFST500-BRFLC Hot Blast Stove Radiation Pyrometer
Product Overview
The HWFST500-BRFLC Hot Blast Stove Radiation Pyrometer is a high-performance infrared temperature measurement system specifically designed for monitoring the temperature of hot blast stove domes and air ducts in ironmaking blast furnace operations. It uses non-contact infrared radiation measurement instead of conventional thermocouples, providing fast and accurate temperature data under conditions involving frequent temperature changes, pressure fluctuations, vibration, and difficult installation environments.
The system integrates optical sensing, electronic signal processing, cooling, air purging, and protection against water and dust. Its dedicated protective assembly enables reliable operation in high-temperature, high-pressure, and outdoor environments, helping maintain continuous temperature monitoring without requiring blast furnace shutdown for routine measurement maintenance.

Key Features
• Specifically designed for temperature measurement of hot blast stove domes and air ducts
• Non-contact infrared temperature measurement eliminates many limitations associated with thermocouples
• Fast response and high measurement accuracy
• Microcomputer-based data acquisition and signal processing
• Imported key electronic components for stable and reliable operation
• Adjustable slope and emissivity settings
• Slope adjustment range: 800–1200
• Emissivity adjustment range: 0.10–1.00
• Dedicated sealed viewing window with moisture removal, anti-condensation, and thermal insulation functions
• Flange connection for convenient installation on stove domes or air ducts
• Stainless-steel ball valve for opening and closing the sight tube
• Integrated cooling and air-purging system for improved measurement reliability
• IP33-rated protection against dust and water
• Designed for continuous operation in demanding blast furnace environments

Working Principle
The HWFST500-BRFLC measures the temperature of the hot blast stove dome or air duct through an opening perpendicular to the dome cover and connected to the regenerator, or through an existing thermocouple measurement port.
The optical receiving unit detects infrared radiation emitted by the measured surface. The temperature signal is transmitted through a dedicated cable to the secondary instrument installed in the measurement and control cabinet. After signal processing, the system displays the measured temperature and provides multiple output signals for connection to computers, recorders, or other control systems.
This non-contact measurement method avoids direct insertion of a temperature sensor into the high-temperature process, reducing the influence of installation depth, mechanical vibration, pressure fluctuations, and thermocouple response lag.
