Ther­mo­graphy in Plastics Industry

The 10 Gigabit Ethernet interface of the high-end camera series ImageIR® opens this extremely fast transmission standard with a NIC specially developed by InfraTec. This works with optical or electrical transceiver modules that are easy to change and are called SFP+.

Stationary camera systems are usually used PC-controlled. Alternatively, InfraTec offers a solution that makes the operation of the camera system even more versatile. An additional tablet PC is attached to the camera housing, which enables wireless control of all camera functions. The display solution allows access to all functions of the IRBIS® online control and acquisition software, delivered together with the camera.

The combination of a separate filter and aperture wheel, allowing a total of 35 freely selectable combinations, is prerequisite for a universal application in measurement tasks with high object temperatures and in the field of spectral thermography. The neutral density filters used for signal attenuation or the combination of spectral filters and apertures reliably prevent interference effects.

The multispectral feature makes it possible to record sequences with constantly changing spectral filters. Images are recorded synchronously with a rapidly rotating filter wheel equipped with the filters. It may be possible to switch between up to seven filters, depending on the version. Due to this the multispectral measurement can be optimised to suit the measuring task if the preset ranges are unsuitable. The integration times can be adapted within the limits calibrated for this filter.

Thanks to HighSense, ImageIR® users have the option of setting up individual measuring ranges based on the factory calibration that best suit the respective task. Depending on the measuring task, the required temperature range can be selected and the optimum integration time for this purpose is calculated – or one decides to proceed in reverse order. Thus, the calibration can be retained even in the case of changed integration times.

The Auto Calibration option expands the HighSense function to include automatic, dynamic adaptation of the integration time. This ensures the utmost temperature measuring accuracy and an optimised signal-to-noise ratio throughout the process. The wellfill of a detector is usually optimal in certain areas of the dynamic range. If the measured object signal is outside theses or user-specified limits, the integration time is readjusted.

With the innovative EverSharp function all objects of the image scene are displayed sharply, not depending on camera distance or lens. With the help of special algorithms thermal images with different focus positions are combined automatically, so that only the sharp object structures are displayed in the resulting thermal image. Thus, thermal images turn out very impressive as all objects are displayed in superb image quality.

Contactless measurement of temperature distributions and profiles with industrial thermographic cameras permits efficient monitoring and control of temperature-dependent processes and procedures within a system-integrated quality assurance programme in industry.

Check the microstructures of sheet metal parts during the stamping process and establish a uniform high strength and quality of all produced stampings safely and with a contact-free method.

Using pulse thermography, WELD-CHECK enables you a quantitative assessment of the inspected welds.

Detect inhomogeneous temperature distribution and local power loss during the production using the Lock-in Thermography.

Infrared cameras allow the non-destructive and process-synchronous monitoring of coating processes to ensure that the coatings are free of defects as soon as they are applied.
