  • All content is this presentation is protected - © 2014 Pelco Infrared Technology for Operational Video
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Fundamentals of Infrared Technology Unique Attributes of Infrared Technology Overview: Training Agenda – Session 1
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 FUNDAMENTALS OF INFRARED TECHNOLOGY Understanding the Technology
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 What is an Infrared Camera? A camera that sees part of the electromagnetic spectrum that is invisible to humans -- it sees heat, NOT light. Best at detecting humans and vehicles. Thermal Imaging: 8-12 m Visible light: .4 m - .7 m Infrared: 0.7m - 20m Cosmic Rays Gamma Rays X-rays Ultraviolet (UV) Infrared (IR) Microwaves Radar Radio Broadcast Band Ultraviolet (UV) Visible Light Infrared (IR) Short Wavelengths Long Wavelengths 1 Nanometer 1 Micron 1 Millimeter 1 Meter 1 Kilometer
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Infrared Spectrum Visible Cameras Visible Light Spectrum 400 – 750 nm (0.4 to 0.75 um) LWIR Thermal Camera 8 – 12 um The earths atmosphere only transmits some wavelengths of light, other wavelengths are absorbed. Visible Camera Night Mode operates out to 1000nm (1 um) Any object at a temperature > absolute zero will emit radiation but the wavelength of the emitted radiation depends on the temperature.
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Key difference: Thermal vs. Visible Visible Cameras Require Illumination Thermal Cameras Require NO Illumination Reflected Light Radiated Heat
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Long and Mid Wavelength Infrared • MWIR (Mid-Wave Infrared) cameras use the 3-5 m band – Known as MWIR (Mid-Wave Infra-Red) – Used to measure high temperatures (>250oC) – Much more sensitive, long range – Require cryogenic coolers (maintenance) – Are expensive by comparison • LWIR (Long-Wave Infrared) cameras use the 8-12 m band – No cooler, almost no maintenance – Used to measure temperatures from -10oC to 250oC – Much less expensive – Optimized for detecting people and vehicles
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Why Use Infrared Technology? • Accurate automated analytics for detecting people and vehicles – Perimeter detection – People and vehicle directional counting • Contactless temperature measurement – Process monitoring & Predictive maintenance – A large number of points need to be monitored – Problematic to instrument with point sensors • Ability to “see” normally invisible gases
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Infrared Imaging Works in Tough Environmental Conditions • Advantages over standard cameras include: – See in complete darkness – See through obscurants (smoke, dust, haze, etc.) – See through particulates (fog, rain, snow) – See beyond the glare of a bright light
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Thermal Advantage: Avoid Glare • Thermal imagers see heat, not light – This means they are not effected by bright lights like standard cameras – They work equally well day and night • Important: This is not just a night- time technology!
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 THERMAL VIDEO ANALYTICS Understanding the Technology
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Thermal Analytics Enables Many Applications People Counting Queue Management Occupancy/Space Utilization Thermal Excels at People and Vehicle Detection/Counting Due to High Image Contrast Thermal Integrated Analytics
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Thermal Video Analytics Behaviors • Analytics 1. Adaptive Motion 2. Loitering Detection 3. Object Counting 4. Stopped Vehicle • Analytics “At The Edge” – Reduces infrastructure / server burden
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Examples of Analytic Behaviors Auto Trip Left Count all trip wire People directional trip wire
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 THERMOGRAPHY Understanding the Technology
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 What is Thermography (very general description) Measure the temperature of any object in the camera’s field of view –Easily set alarm temperature –Send an alarm when the temperature of the object exceeds set point –Record or monitor temperature trend information
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Thermography Analytics Analytics built into the camera: 1. Absolute temperature – Measures the actual temperature of an object and alarms when the object exceeds, or drops below a temperature set in the analytic 2. Relative temperature – Measures the temperature of 2 or more objects and alarms when difference between the temperatures of objects exceeds the temperature set in the analytic. 3. Self Reference – Takes the initial temperature of an object during set up and alarms when the object’s self referenced temperature exceeds a specified temperature delta.
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Sarix TI Thermography “temperature specs” Temperature Measurement – Range: –20° to 120°C ( -4° to 248°F) – Reading Accuracy: ±2°C or ±2% of reading (whichever is larger) Target Distance Range: 2 to140m
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 INFRARED GAS LEAK DETECTION Understanding the Technology
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Key Concepts To Make The Cloud Visible • The gas must absorb infrared radiation in the waveband that the camera can see • The cloud must have a radiant contrast to the background • The apparent temperature of the cloud must be different to the background • Cloud motion assists the visibility of the gas Gas Cloud
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 How Infrared Gas Detection Works • The mid wave infrared (MWIR) gas detection camera has a detector response of 3-5 μm which is further spectrally limited to 3.3 μm using a filter. • This makes the camera responsive to many types of gases Gas Absorption Spectrum Camera Sensitivity
  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Gas Imaging Technology: Applicable Industries • Oil Refining – Infrared cameras have excellent sensitivity to the crude oil fractions from gasoline to kerosene. • Petrochemical and Chemical – An MWIR camera has excellent response to many of the chemicals used in these industries. • Power Generation - Gas fired power stations use natural gas as fuel. The mid wave camera is used for leak detection • Natural Gas – MWIR camera clearly sees methane and ethane and is used for leak detection from the gas production field right through the distribution network.

  • Pelco by Schneider Electric – Thermal Imaging – 5//21/2014 Handheld Thermography Limitations • Two Full Time Team Members take manual pictures of the cables and motors. • Over temperature condition it is logged • This method is only 30 percent effective • Most faults are found after a cable/motor has failed and production is impacted. • These failures create 30-60 minutes of downtime per event.
