Ready to ShipThere are many types of thermal cameras, each serving a specific industrial purpose. Here are the most common ones:
Longwave infrared cameras
These imaging cameras work best within the 8-14 mm wavelength range. They are used for capturing thermal images of structures and machinery with a temperature range of 0-600°C. Long-wave infrared cameras are ideal for detecting insulation defects in buildings, as they can see spots invisible to natural light. They are also suitable for fire safety checks in industrial areas.
Midwave infrared cameras
These devices operate within the 3-5 mm wavelength range. They are commonly used in the aerospace and military industries to capture images of thermal signatures from heat sources. Aviation maintenance crews can use mid-wave infrared cameras to inspect aircraft parts for overheating. Thermal imaging cameras for health checks of electrical components on construction sites are also ideal.
Shortwave infrared cameras
These cameras operate within the 0.9-2 mm wavelength range. With their ability to capture images in extreme temperature conditions, these cameras are commonly used in industrial inspections. These cameras are applicable for detecting thermal anomalies in areas with high heat.
Thermal imaging cameras
These are multispectral cameras that can detect and image temperature distributions on an object surface. By capturing thermal radiation across different infrared wavelengths, these cameras provide a comprehensive view of thermal patterns and anomalies. People use thermal imaging cameras in diverse applications such as building inspections, veterinary care, firefighting, and preventive maintenance in industrial environments.
It is necessary to understand some of the prominent features that these imaging cameras include:
Automatic calibration
Many infrared thermal cameras come with this advanced feature that allows automatic calibration of temperature measurements. These devices ensure precise readings and consistent performance by adjusting internal parameters based on reference points. Automatic calibration reduces user intervention, making the device easy to use in various environments.
Optical vs. Thermal Resolution
These resolutions refer to the detail captured in thermal images. The thermal resolution usually counts the number of infrared pixels, while the optical resolution pertains to the detail captured by the visual camera. Thermal resolution is vital for applications where small temperature variations need detection, such as on construction sites. At the same time, optical resolution is essential for correlating thermal and visual data accurately.
Thermal sensitivity
It is also called thermal resolution or the ability of a thermal camera to detect slight temperature differences. Cameras with high thermal sensitivity can spot temperature variations as small as 0.1°C. This feature enables users to identify potential issues before they become significant, making it essential for preventive maintenance, building inspections, and monitoring electrical equipment.
Image fusion
This feature is where a thermal imaging camera combines thermal and visual images to create a composite picture displaying both data types. Image fusion enhances the analysis by providing context to the thermal readings, making it easier for users to diagnose issues in various settings. This is especially useful in industries where accurately identifying heat patterns is crucial.
These are the steps on how to use these infrared thermal cameras:
Turning the camera on and adjusting settings
To get started, users have to turn on the thermal camera and adjust important settings such as thermal sensitivity, emissivity, and color palettes. These settings depend on the environment and the objects to be thermally imaged. Emissivity adjustment ensures accurate readings on different surfaces while thermal sensitivity helps detect temperature variations.
Scanning the target area
A user should slowly move the camera to scan the entire field of view. It is important not to rush the scanning process, as taking time lets the user capture detailed thermal images. Getting close up is not always necessary; maintaining a proper distance while adjusting focus can improve image clarity and detail.
Capturing images
Once the optimal angle and position for the image capture are found, users must press the capture button to store the image. Most thermal cameras allow users to capture multiple images for later analysis. So, if an incorrect picture is taken, don't worry; more can be retaken.
Analyzing the captured images
After capturing images, users should analyze them to identify thermal patterns and anomalies. Interpreting these images involves paying attention to color variations and heat signatures that may indicate underlying issues. Click here to consult an expert, as accurate analysis requires practice and experience.
Generating reports
After analyzing the thermal images, users need to create detailed reports for documentation and sharing with clients. These reports often include annotated images, temperature measurements, and corresponding observations. Reporting software linked to the camera can simplify this process.
Buyers should pay attention to these factors to choose the best thermal cameras:
Display and interface
A good camera has a bright display that enables users to see clear images, even in harsh lighting conditions. An intuitive interface with easy controls and menus ensures quick adjustments in the field. A user-friendly setup reduces the learning curve and allows for more efficient operations when analyzing and reporting.
Lens choices
The thermal imaging camera lens is responsible for focusing on the heat signature and creating a sharp image. The most common lens used is the standard lens, which is suitable for close-range imaging and capturing detailed fields of view. There are also wide-angle lenses that capture up to 90 degrees, making it easier to view large areas fast.
Focus options
Buyers should consider that there is a focus option: manual, auto, or intelligent. An autofocus or intelligent focus option quickly adjusts the focus while operating the camera, allowing users to capture sharp images despite rapid movement. This feature is particularly useful in dynamic environments where accuracy is crucial.
Testing and certifications
These factors ensure the cameras perform well in harsh conditions. Buyers should always go for cameras with IP67 ratings, as they protect the gadgets from water and dust. MIL-STD-810G certification means the camera can withstand drops, extreme temperatures, and shocks. Industries such as construction or oil and gas may require infrared mapping cameras to function reliably in adverse conditions.
Yes, they can, of course, since they capture the heat emitted by objects. This allows them to create clear images based on thermal radiation, even in complete absence of light.
Some of these cameras can provide this feature. At the same time, most of them operate primarily in the longwave infrared range. Midwave and shortwave cameras can capture images and heat signatures in different environments.
Users should regularly clean the lenses with a microfiber cloth to avoid a buildup of dust or smudges. They should also store the device in a protective case to prevent damage. Performing software updates will ensure peak performance for the camera and add new features.
Some of these cameras come equipped with rigorous IP ratings for exposure to water, dust, and even extreme temperatures. These thermal mapping cameras are ideal for construction, manufacturing, and outdoor inspections.
These cameras easily detect temperature variations from -20°C to 350°C. Those with more advanced features can detect up to 1500°C. Select the thermal camera based on the specific temperature range requirements of the intended application.
