A Rechargeable Thermal Imager Can Detect Leaks of Sulfur Hexafluoride at Temperatures Up to 500degC
The thermal imager is an electronic device that enables the user to see temperature values in real-time. The temperature range of the device is from -4degF to 752degF, with an accuracy of two to three degrees. The device is capable of detecting hot spots in engines, wiring, and even behind walls and clogs. It comes with crosshairs for pinpointing specific temperatures and options for setting alarms. A rechargeable 1350mAh Li-ion battery powers the thermal imager. You can use this device with any computer or laptop, as it requires only a USB power source.
Detects gas leaks
A new device allows utility crews to perform a gas and infrared inspection whenever they need to. The portable, non-contact tool can detect leaks of sulfur hexafluoride (SF6). This technology eliminates the need for special annual leak inspections and reduces the risk of damage to equipment. One of the most attractive features of this thermal imaging camera is its ability to detect leaks at temperatures up to 500degC.
The device has a rugged, high-resolution tilt-able viewfinder and an intuitive user interface. The TI320+ also comes with SmartView(r) software, a modular suite of tools for thermal imaging. The device is easy to use and includes a user guide and material tables. With an easy-to-follow user manual and a Wi-Fi connection, the TI320+ is ideal for both indoor and outdoor use.
Detecting voids in roadways is a significant issue. Cracks, culvert failure, and drainage piping can cause voids in the soil below pavement. In order to find these problems, new non-destructive approaches are needed. Fortunately, new non-destructive approaches are emerging that will outperform current techniques. This project will develop a portable, rechargeable thermal imager for use in these applications.
Thermal imaging is an excellent technique to detect delamination in composite materials. This thermal imaging tool takes measurements of the heat output and patterns from the structure under investigation. It is a cost-effective way to detect defects in composites. In the event of delamination, it is possible to detect the damage early enough before it causes major consequences. This is where an IR-Thermography camera comes in handy.
The method can be described with reference to FIGS. 2 and 3. The blade 15 is first blackened with a paint spray gun 24 and then placed on the test part holder 3 of the turntable 17. The parameters are input to the personal computer 19 and then processed by the control unit 4. The test position faces the thermography camera and flash lamp units. It takes the measurements in real time and can be used to monitor the quality of concrete.
A 5-minute heating cycle for a 3 cm-deep delamination allows a good estimate of the size of the defect. More heating is needed for deeper defects, but this is impractical for most cases. We found that heating for five minutes is sufficient for detecting defects of one to two centimeters. A difference of 20% to 28% between the estimated and actual area is normal. When the delamination was three centimeters deep, we found that the contrast between the two areas was less than 0.1degC.
Detects voids in laminates
A rechargeable thermal imager can detect voids in a laminate by using a photoresistive detector (CRD) to measure heat transfer. Unlike other types of thermography, this method can accurately detect voids on composite surfaces. These materials are typically cured in an autoclave, so there is a risk of volatiles leaking into the laminate. Using a thermal imager is the most accurate method for identifying voids and avoiding costly scrap.
In addition to its high temperature and low-temperature resistance, a void-free laminate of polyimide film is useful for packaging and encapsulation of goods in high-temperature environments. Because Kapton(r) has poor through-the-thickness strength, its use in certain applications is restricted. Using a thermal imager to detect voids in a laminate allows the production of thick laminates without degrading individual layer strength.
Detects voids in wood
A rechargeable thermal imaging system for wood inspection is a highly effective tool for detecting knots and voids in wood. The system uses an infrared camera that scans a wood surface. After a wood surface has been heated using any method, the wood is moved in front of the infrared camera. Depending on the type of thermal imaging camera, it may be a line-scan camera or a field-view camera.
These tools have several advantages. They can accurately detect voids and knots in wood, and the image is displayed digitally. The thermal profile of a wood surface after it has been heated can help in controlling wood quality and programming lumber saws and treatment operations. Aside from this, the technology is also useful for determining the size of knots in a piece of wood. In addition to detecting voids, it can also help in determining the size and location of a knot.
Detects delamination in wood
A thermal imager is an important tool for detecting wood delamination. This tool detects changes in surface temperature, which is indicative of delamination. The more delamination a piece of wood has, the greater the surface temperature difference. Thermal images of delaminations are easier to distinguish if the depth of the delamination is less than 4 cm. If the depth of delamination is greater than 4 cm, the delamination may be a splinter.
The device detects defects at 1 and 2 cm depth with high accuracy. The longer the heating time, the deeper the defect appears. Unfortunately, this is not practical, and a five-minute heating time is sufficient for all delaminations that are at a depth of two centimeters. In one study, a 3 x 3 cm delamination was detected with a difference of 10% to 28% in absolute temperature contrast.
Using a thermal imager to detect delamination in wood, a wood inspector can determine if it is a problem with the structural integrity of a timber floor. The device shows the temperature of the delamination and its depth using a thermogram. The graph shows a delamination at both daytime and nighttime. Its WTDR can detect delaminations at any depth in a piece of wood as long as it is smaller than the average delamination.
