Thermal Imaging Cameras
Thermal imaging cameras, also known as thermographic cameras or infrared (IR) cameras, are handheld, non-contact devices used to capture images in low-light and hard-to-see areas. They do this by detecting infrared energy (heat) and converting it into an image. Typically, thermal imaging cameras are used for troubleshooting, identifying potential hotspots and ensuring machinery and equipment run correctly and efficiently.
How Does A Thermal Imaging Camera Work?
Thermal imaging cameras are point-and-shoot devices that enable the user to scan an area in an infrared spectrum, interpreting temperature as colour. Warmer areas appear as red and yellow, and cooler areas as purple or blue. Thermal imaging cameras use an external lens to focus infrared energy on an internal thermal sensor. The sensor, along with processing electronics, converts the heat and uses the captured data to create images. Images can be used for immediate diagnosis or can be stored and processed through dedicated software for further evaluation.
What Do Thermal Imaging Cameras Detect?
Any object with a temperature above zero will give off thermal energy. The hotter an object is, the more thermal energy will be emitted. So, essentially, thermographic cameras can detect anything that produces a heat signature.
Thermal Cameras for iPhone and Android
Thermal cameras are now available for integration with smartphones like iPhones and Android devices. These compact attachments turn your phone into a thermal imaging camera, providing portable, easy-to-use temperature detection for professionals. They are perfect for quick inspections, offering the flexibility of thermal imaging without the need for a standalone device.
Thermal Imaging Cameras Applications
The possibilities are endless! Thermal cameras were originally developed for military and surveillance operations, but now their useful technology enables the cameras to be used in a wide range of other applications. Some of the most common are:
- Electrical engineering – Used to identify hotspots in electrical enclosures. Engineers can detect potential equipment failures caused by equipment overheating.
- Fire Service – Firefighters use thermal imagers to see through smoke and localise fire hotspots.
- Automotive Industry – Mechanics use thermal imaging cameras for engine diagnostics
- Medical – Doctors, nurses and vets can also use these cameras as thermometers, detecting fevers in human temperature or identifying temperature differences in animals.
- Construction – Building inspectors use thermal imagers for checking insulation and for detecting leaks in heating systems.
How to Choose the Right Thermal Imaging Cameras
When selecting the right thermal imaging camera, it's important to match the features of the camera to the specific demands of your application. These are some of the factors you need to consider:
1. Temperature Range
The temperature range of a thermal camera defines the limits within which it can detect heat variations. If you're working in high-heat environments, such as industrial furnace inspections or engine diagnostics, you'll need a camera capable of handling extreme temperatures. For general maintenance or home inspections, a camera with a moderate range may be sufficient.
2. Resolution
The resolution of a thermal imaging camera determines the clarity and detail of the thermal images it produces. Higher resolution is critical for applications requiring precision, such as building inspections, where fine details like small insulation gaps or moisture spots need to be detected. A higher-resolution camera provides more pixels, meaning more detailed thermal images, which can be crucial for tasks requiring accuracy and clear visuals.
3. Field of View (FOV)
The camera’s field of view refers to the area the camera can capture in a single image. A wide FOV is useful when inspecting large areas, such as electrical panels or scanning building exteriors, as it allows you to cover more ground with each shot. On the other hand, a narrower FOV offers more focused detail and is beneficial for applications requiring close-up inspections, such as evaluating specific components in machinery.
4. Additional Features
Advanced thermal imaging cameras come with a range of additional features that can enhance their functionality. Some models offer data storage and analysis, allowing users to capture thermal images and process them later using specialised software. Other thermal imaging cameras may feature Wi-Fi or Bluetooth connectivity, enabling users to transmit images and data directly to a device or network of devices for real-time sharing.
By carefully considering these factors, you can ensure that your chosen thermal imager will meet the demands of your specific tasks.
