High-resolution low cost IR cameras

November 2016 Temperature Measurement

Cox has just released its latest low cost high-resolution thermal imaging camera fixed applications that need quality images at a cost effective price. Many ‘low cost’ imaging cameras have a resolution of 160x120 px or lower, but the new Cox units have two standards, 384x288 and 640x480 px resolution.

Radiometric application thermal cameras.

All CG series radiometric models are built with the latest version of thermal detectors from ULIS: the QVGA Gen2 and VGA Gen2 respectively. These detectors have better NETD (noise equivalent temperature difference) than detectors for former CX series models, and just a few cycles of NUC (non-uniformity correction) in a day is good enough because they are shutter-less compatible. Even though NUC is not performed every 5 minutes, image quality is better than former CX series models.

By increasing the processing capacity, CG series cameras have more detailed features such as alarm and ROI settings, which were previously only available in thermal imaging analysers.

CG series radiometric thermal cameras are fully controlled by a thermal imaging analyser on a PC. SDK for thermal imaging analysers, working in Windows and developed in C++, is provided for customers who wish to develop their own version of thermal imaging analyser.

Radiometric network thermal cameras

CG320-IP and CG640-IP are thermal network cameras transmitting video and temperature data simultaneously. The core is exactly same as the CG320 or CG640, with normal temperature detection mode (measure up to 120) or high temperature detection mode (measure up to 650) respectively.

CG320-IP and CG640-IP are unique thermal network cameras in that they transmit compressed video and temperature data, including temperature alarms, simultaneously via an IP network. The user can set an alarm temperature in each section (32x32 pixels), or in a group of sections in minimum, maximum or average temperature. If the temperature of any section or group of sections exceeds set temperature, the camera sends alarm data to the alarm management software.

Cox thermal cameras are supplied with a variety of lenses to suit customer requirements for projects. Focal lengths from 4,8 to 250 mm are available in manual or motorised lens.

Various continuous zoom lenses, 2FOV lenses, and thermalised lenses are also available.

These flexible low cost IR cameras provide real-time thermal images for process applications in a wide range of industries like petrochemical, iron and steel, automotive, food and beverage, and plastics. With the use of the provided software tools, users can interface with existing control systems either digitally or via single analog and digital outputs. Cox thermography cameras with macro-lenses to measure the temperature of very small parts like the pins of a chip on a PCB are also available.
