Abstract

The lead-off probe is used in the power industry. It ensuresfaultless measuring of 02 without demanding compulsory switchingoff of the steam generator to clean the probe. It consists of atube (1) with leading off apertures (6). A device (7) forattaching instrument (13) for measuring 02 is fitted in tube (1).A cleaning device (4) for cleaning the apertues (6) and device (7)is introduced in tube (1).8 claims, 2 figures
