Linear termographic cameras

The Pyroline series is the line of linear thermographic cameras of our brand represented by DIAS INFRARED for non-contact temperature measurement in continuous production processes.

Linear thermographic cameras are used in applications where the object to be measured is in motion and allows the camera to make the thermal map depending on the speed of the material to be measured.

  • Advantages of the linear camera with respect to the scanner:
  • The mechanical scanner is not used
  • Greater measurement speed More than 512 lines per second
  • Use of uncooled infrared sensors (uncooled sensor)
  • Simultaneous measurement for all measurement points.

PYROLINE linear thermal imaging cameras are available in different housings, temperature ranges, wavelengths and also the number of pixels in the detector. PYROLINE linear thermal imagers can offer a resolution of 128 pixels or 256. There are also different types of optics that allow cameras to be adjusted for different distances and fields of action. The working frequency of the PYROLINE cameras is 256 lines per second.

There are different types of wavelengths, each of them is specially designed for the measurement on a type of material or for certain ranges of temperature.

Below we detail the different linear thermographic cameras by temperature range and wavelength.

Compact + and protection housing

We have the Compact + housing for linear thermographic cameras, ideal for use in non-aggressive environments. The Compact + model is a compact and robust housing. You can know more about this case on this link.

For more aggressive environments or where the 60 ºC ambient temperature is exceeded we recommend the use of the Protection housing that allows linear thermal imaging cameras to withstand temperatures above 150 ºC. You can learn more about protection of PYROVIEW cameras in this link.

There is a wide range of different applications. In all applications where temperature is important, our remote temperature measurement systems can be used. The different housings, optics, temperature ranges, spectral ranges and mechanical accessories allow our linear thermographic cameras to offer the best solution for each application.

Fixed linear thermographic cameras can be used in this type of applications:
