Product Description
VOCs Gas Leak Detection Cooled MWIR Thermal Imaging Detector
High-performance 320×256 resolution cooled infrared detector with 30μm pixel size for precise VOCs gas leak detection in industrial applications.
Product Overview
The LFD330Z3 cooled infrared detector is specifically engineered for VOCs gas leak detection in the petrochemical industry. It converts infrared radiation in the 3.2~3.5μm wavelength range into electrical signals, enabling remote visual detection of minor leaks for gases including methane, benzene, and ethanol.
This advanced detector facilitates efficient gas operation monitoring and safety production warnings, with applications spanning atmospheric environment monitoring, pollutant discharge analysis, and chemical gas detection in petrochemical plants and refineries.
Key Features
  • Optical Gas Imaging: Long-range non-contact detection with high efficiency and security across wide detection ranges
  • High Sensitivity: Cooled infrared detector technology effective for low gas concentration and slow gas flow applications
  • Comprehensive Gas Detection: Effective for alkanes, alkenes, alcohols, benzenes, ketones, and other volatile organic compounds
  • User-Centric Design: Multiple cryocooler options available for lightweight, low-power, long-life, high-reliability operation

Frequently Asked Questions
Advantages of Optical Gas Imaging
  • Time-saving & Efficient: Supports large-scale real-time detection with rapid leak location without interrupting production
  • Long Range Detection: Operates from safe distances in dangerous and complex areas with non-contact, non-destructive testing
  • Easy to Analyze: Provides intuitive imaging with instant storage and convenient analysis capabilities
  • Multi-function Inspection: Detects multiple gas types with excellent remote temperature measurement functionality
Working Principle of Optical Gas Imaging
Optical gas imaging utilizes infrared technology to visualize invisible industrial gases. After absorbing infrared radiation at specific wavelengths, radiation differences occur between the gas and background. The gas leak detection infrared detector with built-in narrowband filter receives infrared bands near gas absorption peaks, converting gas presence into visible infrared images through radiation differentials.
