Abstract:

A description of vacuum-measuring instruments is presented. The system based on the principle of using reversed magnetrons Redhead is recommended, because of their versatility, their ability to measure at low pressures in the range of 10 to the -5th power to 10 to the -12th power torr, and their logarithmic reading scale. Such a device known as a picalog, has been constructed by VEB Hochvakuum Dresden. However, it has scale readings distorted by the pump operation. This shortcoming can be eliminated by the installation of a measuring cell and a magnet open in the receiver. Leak detection methods are discussed. Heating problems and modern cost reduction techniques are cited. Various flanges and seals of different countries are compared. The different types of valves are discussed. Author
