Encapsulated magnetostrictive acceleration pick-up for high temperatures

摘要: The present invention relates to a magnetostrictive acceleration pick-up for temperatures of 600 DEG C or more and other difficult environmental conditions. is be particularly suitable signals in frequency range approximately 5 30 kHz suitable, example, acoustic monitoring large components power stations. For this purpose, the actual core (1, 2) arranged magnetic screen (6a, 6b, 6c, 6d) an outer protective housing (7a, 7b, 7c, 7d). A diamagnetic intermediate plate (5) separates 2), magnetically from 6d). (5), base (6a) (7a), are soldered one another planar fashion. additionally has damping member (4), preferably made tantalum, which on
