Method and device for monitoring the operation of an X-ray tube of an analysis apparatus, especially for cement raw meal

摘要

In order to be able to identify better and more reliably disturbances in the cooling water flow of the cooling circuit of an X-ray tube (2) which is integrated into an X-ray diffraction system or an X-ray fluorescent analysis test set for cement raw meal, and is equipped with a flow monitor (4) and a temperature monitor (5), the anode region (2') of the X-ray tube (2) is additionally equipped with a further temperature measuring device (7) which detects the surface temperature of the tube body directly. The temperature measuring device (7) is preferably designed as a bimetallic switch having a small heat capacity, so that rapid identification of unacceptable temperature changes and switching off of at least the X-ray tube (2) is ensured. <IMAGE>
