PYROLINE WBS – Temperature measurement on gypsum wallboards

Infrared line camera system for gypsum application

The system solution PYROLINE WBS has been specially developed for non-contact temperature measurement on gypsym wallboards. The infrared line camera PYROLINE of DIAS measures temperatures up to 512 Hz in real time.

The providing of an equal temperature and humidity distribution during the drying process of the gypsum wallboards is important for their quality. Inhomogeneity can lead to deformations or the breaking of the plates. Specifically adjusted measurement systems are required to measure the temperature distribution without contact and to identify problem areas. The infrared measurement technology allows the fast acquisition of the surface temperature over the whole gypsum wallboard.

DIAS Infrared offers as a German manufacturer an appropriate infrared measurement system for the non-contact temperature measurement on gypsum wallboards: PYROLINE WBS (Wallboard System)

PYROLINE infrared line camera for the non-contact temperature measurement and detection of temperature profiles

The DIAS PYROLINE infrared line camera is an uncooled ir camera for the industrial use. It has 128 or 256 sensor elements and provides line frequencies up to 512 Hz.

The industry stainless steel housing (IP65) with air purge unit and optional water cooling guarantees the long-term operation in rough industrial environment.

The data transmission happens via Fast Ethernet in real-time over great distances.

Differences in temperature can be detected and processed for process control.

The DIAS PYROLINE infrared line camera is unique and offers a lot of advantages in contrast to the use of line scanners.

The infrared line camera PYROLINE serves to record temperature profiles with a resolution of 128 x 1 or 256 x 1 pixels (H x W)

The application specific thermal imaging software IR WBS allows the monitoring of the thermal images of gypsum wallboards, the display and storage of temperature profiles of single dryers as well as the display and storage of trend development. Digital inputs are used to assign current measured data to the appropriate dryer. Password protected user levels and simple touchscreen operation enable the immediate use in the production process.

Features of the thermal imaging software IR WBS:

  • Real-time thermal image of gypsum wallboards
  • Storage of profiles and trend developments
  • Profile view for up to 16 dryers (current and history)
  • Profile view of single gypsum wallboards
  • Trend development for process and gypsum wallboard temperature
  • Editable product list
