Product Description
Cooled MWIR Thermal Imaging Detector 640×512/15μm for Visualizing VOCs in Petrochemical Industry
Volatile organic compounds (VOCs), widely distributed in industries such as petrochemicals, present significant safety risks due to their volatile, flammable, explosive, and toxic nature. Traditional detection methods often suffer from limitations including short detection distances, restricted search ranges, and lack of intuitive visualization.
The LFD615HZ3 infrared detector for gas leak detection leverages industry-leading T2SL technology and HOT device technology, offering superior SWaP³ performance advantages. This enables more precise leak detection, comprehensive coverage of common VOC gas types, and significant improvements in operational safety levels.
Key Features
  • SWaP³ Optimization: Smaller size, lighter weight, lower power consumption
  • Clear & Identifiable Leakage: 640×512 resolution with gas enhanced HSM algorithm support
  • High Reliability & Sensitivity: Superior detection performance
  • Easy Integration: Supports various interfaces and RAW/YUV image output
  • Full Scene Coverage: Suitable for handheld and long-term online applications

  • Enhanced Inspection Safety: Reduced accident risk and minimized operational losses
Frequently Asked Questions
What is NETD?
NETD refers to "Noise Equivalent Temperature Difference". It measures a thermal imaging detector's ability to distinguish between very small differences in thermal radiation. NETD is typically expressed in milli-Kelvin (mK), where lower values indicate higher thermal sensitivity.
What is SWaP³?
SWaP³ refers to size, weight, power, performance and price, representing the key technology trends in the infrared industry.
What is DRI?
DRI typically refers to detection, recognition and identification distance of a thermal imaging system, serving as a crucial performance parameter.
How to select the right pseudo color for thermal imaging?
  • Gray white is more suitable for targets with small temperature differences
  • Red and blue are more suitable for identifying problem points in scenes
  • Iron red serves as the standard color palette for the power industry
Note: The thermal temperature remains unchanged regardless of palette selection.
