Mesa de Calibración AT-03

AT-03AT-03 Automated calibration stand is designed for positioning of standard and calibrated dose rate and dose measuring instruments in X-ray field.








Operation principle

Calibration stand provides positioning of standard and calibrated equipment on the desktop and moving them to a specified working distance from the X-ray irradiators using a positioning system.
Stand coordinates are linked to the center of the irradiator and of the X-ray beam axis based on the alignment results using the measuring rods and laser systems.
Stand management functions are carried out by the software and a portable control panel.
The video surveillance system is used for remote reading of indications on the scales of calibrated devices. 



Metrological assurance of x-ray dosimetry:

  • Application in the reference and calibration dosimetric installations for X-ray
  • Metrology laboratories to graduate and verify dosimetry equipment
  • Second standard dosimetry laboratory (SSDL)



  • Precision positioning of the reference and calibrated equipment
  • Positioning of the moving tableto the coordinates X, Y, Z using digital servos
  • Centering the reference and calibrated equipment using stands, measuring rods and laser systems
  • Fixation of the coordinate X to the centre of irradiator
  • Automatic and manual positioning
  • Remote monitoring the indicated value of calibrated instruments using video surveillance system
  • Performing function of equipment protection:
    • control and limitation of movement range of  the platform and the desktop
    • feed and control circuit protection with automatic circuit breaker and quick-break fuse
  • Possibility to place one or two X-ray irradiators with filter system
