Miniature IR camera
October 2005
Temperature Measurement
Temperature measurement in the plant has been made more convenient with the MobIR M4, believed to be the first mobile-like pocket IR camera in the world. Weighing a mere 265 g and shaped like a mobile phone, this portable camera is rugged.
Integrated into the camera's casing are both thermal and visible cameras, the former using a state-of-the art microbolometer FPA from French company, ULIS. With its 13 mm IR lens the system offers a field of view of 25 x 19 degrees. The MobIRM4 has a built-in flash memory of 8 Gb and stored file format includes the IR and visible images as well as voice annotation. The data collected is easily downloaded to a PC using a standard USB interface which can also charge the standard-issue Li-ion batteries if required (battery operating life is greater than two hours continuous operation).
The device has an integrated semiconductor laser locator that can be used to accurately associate a hot spot shown in the image with the real physical target. Auto indication of hot spot and image centre allows one cursor to automatically indicate the temperature and position of the hottest spot within the image while the other cursor stays at the image centre to show its temperature and provide a reference for inspection analysis. An audio alarm can also be set to trigger for a spot exceeding a preset value. Post processing software is also provided which is Windows-based and automates the process of reporting and archiving infrared images.
Performance
The camera will measure temperatures in the range of -20 to +150°C and is accurate to ±2°C or ±2% of the reading. Operating temperature is -20 to +60°C. Encapsulation meets IP54 while operational shock of 25 g (IEC 68-2-29) and vibration of 2 g (IEC 68-2-6) can be withstood. If a wider temperature range is a requirement, the larger IR928 from the same company and using the same technology, offers -25 to +400°C as standard with +1000°C as an option.
The MobIRM4 has been designed with a wide range of applications in mind, ranging from energy management, power generation, electronics and electrical manufacturing, as well as for the steel, glass, cement, plastics, injection moulding and other industries.
